Past (to present) Lives of Humans

Overview of humans over time

Eric Lee, A-SOCIATED PRESS

TOPICS: HISTORY, FROM THE WIRES, PREHISTORY

Abstract: An overview of the past ten million years of hominin happenings with a focus on the last ten thousand years of empire-building (complex societies exhibiting an expansion dynamic). Thousands of chiefdom level empires (expansionist complex societies exceeding Dunbar's number) have likely come and gone as unsustainable complex societies (aka civilizations), but were unnamed and may be unknown to history or archaeology and so will go unnoted. State level complex societies are the tip of a much larger iceberg of technology and typically agro-empowered empire-building dynamic more complex than we understand.

TUCSON (A-P) — And then there was:

[omitted are the last 300 years, or 0.03 pixels, of industrial/urban sprawl and behavioral sink]

10,000,000 BP to 6,000,000 BP: The forest dwelling common ancestor of humans and common chimpanzees may have had more in common with chimps than the bipeds that became adapted to the open savanna.

6,000,000 BP: Hominins speciate into multiple forms. Male dominance was selected against to allow the males, who sometimes bring home the bacon, to work more cooperatively together and share equitably.

4,000,000 BP: Human ancestors evolve serial monogamy based on infatuatory-sexual feelings that enable females "in love" to focus on their chosen one such that he "knows" that he is the likely father of resulting offspring and that preferential food (especially meat) gifts he bestows upon his true love, before birth and while nursing his likely child, are appropriate—have an evolutionary payoff. When the child is weaned after a few years, it is largely independent, without need of parental care. When the mother is fertile again, she may choose a different mate. Romance-based serial pair-bonds are programmed to end within a few years (2-4 years per Helen Fisher).

Compare the 2.5–3 million year presence of humans (genus Homo) on Earth to a 75 year human lifespan: a span that we can grasp intuitively. On this scale, we get the following analogous periods:

First 65 - 70 years: various species of humans evolve and coexist (sustainably) on the planet;
Last 5 -10 years: the age of Homo sapiens sapiens (about 200k-400k yrs; mostly sustainably);
Last 15 months: the age of expansion as Man the Hunter, an invasive species;
Last 4 months: the age of civilization (expansionist agriculture; then cities and empires) (11,000 yr);
Last 4 days: the age of science (400 yr);
Last 36 hours: the age of fossil fuels (150 yr of increasingly significant use and rapid expansion);
Last 12 hours: the age of rapid global ecological devastation (50 yr).
Next 12 hours post-climax...?

2,000,000 BP: Hominins roaming Africa may be pre-sapiens, but are close enough to be considered human. [If the past 2 million years of humanity's walk on this planet are compared to the life of a 50-year-old individual living today, almost their entire life would have been lived profoundly different than recent times. They lived nomadic lives in groups of maybe 20 to 50 others they trusted with their lives. The last 10,000 years, the coming of agriculture, cities, and empire-building, would have been in the last four months of their lives. The Industrial Revolution, starting with steam engines happened in the last day and a half and leading up to the last few hours of our so called lives of Facebook enabled cell phones that can take selfies. Few industrial society humans trust anyone with their lives and fortunes, even family, nor can they concern themselves with things more than five years in the future (or one hour), rendering them centered on Self and posterity blind "rats of NIMH".]

1,000,000 BP: Bigger brains require more time to program—there is more to learn and infants are born increasingly more immature to allow the head to pass through the birth canal. Childhood is extended beyond weaning. A woman may have more than one dependent offspring at a time and male support is valued as it may make the difference. Having multiple fathers of multiple dependent offspring doesn't work well. Pair bonding evolves to last more than two to four years based on oxytocin and vasopressin mediated feelings of commitment to allow for long-term monogamy, but the infatuatory-sexual propensity remains as does the promiscuous pattern that preceded the romantic infatuatory-sexual adaptation favoring serial monogamy. Old patterns are not erased before being overlaid with more adaptive patterns, leaving the atavistic patterns to remain or even be selected for among denizens of the human zoos that industrial society's urban growth selects for.

300,000 BP: Human lifespan becomes extended to allow for grandparents to help with child rearing, freeing the younger mothers to roam farther in gathering foods without children in tow. They can gather more food allowing them to feed their parents and extended family too. Grandfathers teach their grandsons to hunt small game and make tools. Women supply most of the food. Men bring home the bacon (sometimes). The social order is matriarchal, matrilineal, and matrilocal. Mythology emphasizes the Great Mother metaphor as in Gaia, Mother Nature, and Mother Earth. Males are exogamous, going to live with their wife's band—a small nomadic group of typically 20-60 people including grandparents and children. The bands of related women are on semi-friendly terms most of the time except during periods of scarcity. Human evolution selects for egalitarian tendencies that favor the gifting economy. Patriarchal alpha male inclinations among men remain but are moderated by cultural egalitarian norms that women favor.

60,000 to 50,000 BP: A single group of humans crossed the Red Sea to disperse globally, becoming the ancestors of all non Africans other than such Neanderthals, Denisovans, and as yet unidentified humans as they interbred with and displaced. Homo sapiens left Africa over 100,000 years ago and were living out of Africa when the single group we descended from came and 'displaced' them, interbreeding with some, but we non Africans descend only from those who made them go away however you may imagine that happening. One group rapidly crossed southern Asia to New Guinea and Australia. Others traveled north to Eurasia via the Middle East about 45,000 BP, spreading throughout Western Europe as hunter-gathers (WEH) about 43,000 BP. This expansion event was the first, followed by a second global expansion of Indo-Europeans and their language and culture 7,000 BP. Non Africans are the result.

Technology empowered animals, prior to evolving self-limiting controls if significant harm is possible, face extinction. Significant empowerment of an animal by technology began with fire making hominins who may have started out putting everything that would burn to the torch because doing so, burning forests and grasslands (at both ends) gives a lovely light!

Hominins, as K-strategists, must persist or go extinct, and using fire maximally for short-term self-interest (e.g. for pleasure or to kill game for one feast) would be selected against. Nomad foragers using fire to diversify a biome and prevent large-scale conflagrations by naturally occurring fires, would be adaptive (maximize empower of the system) and was selected for until modern times when insapient fire starting (arson) became common. Note: our ancestors limited their use of the awesome powers of fire, implying we have the potential to self-limit too.

Within Africa, hominin development of stone weapons was slow enough that prey species were able to adapt, so this technology did not lead to megafauna extinctions until humans went out of Africa and developed advanced technology (e.g. atlatl and Clovis point force-multiplier technology). This was humanity's first failure to limit their use of technology to avoid long term harm to themselves and the local ecosystem. Outside of Africa, fauna initially failed to recognize humans as a threat and were killed too easily. Assume 99% of nomadic bands recognized the potential of overhunting naïve prey to extinction, and limited their taking of any species to avoid any noticeable decrease in their population below optimum (e.g. under grazing) as the decades passed.

Oh, but initially 1% of bands view the animals as a resource for the taking, take, prosper, and easily support large families. And their offspring do likewise only more efficiently and with greater enthusiasm. Soon, all who are expanding out of Africa are enthusiastic expansionists whose culture celebrates taking. As one area is depopulated of fauna, no problem, they move on. This short term expansionism was selected for, for a time. We are their descendants. The pattern worked for millennia, and selected for humans who prospered greatly as an invasive species responding to short-term contingencies of reinforcement (short-term self interest). Eventually an invasive species, however, after overrunning a habitat (e.g. planet Earth) must re-adapt to a steady-state biophysical economy or face local to planetary extinction.

Into a world of nomadic foragers, some came to plant and select for desired traits to domesticate plants (e.g. bottle gourds and food plants), and others domesticated animals as commentalists which allowed the nomadic to settle in one camp and amass possessions far beyond what they could carry. Initially settlements of bands remained band-sized in population, 20 to 50 (range 5-85) trusted others, which was viable, but typically within a few millennia selected for larger populations which selected for hierarchy and the emergence of elites and commoners, the emergence of overcomplex society that selects for growth and expansion (empire building from chiefdom to nation-state), e.g. the global modern techno-industrial form of civilization we are products of, live in, and serve.

About seven thousand years ago a patriarchal culture, dominated by hunters (as on the steppes of Asia there were few plants to gather) acquired domesticated cattle and later horses, developed metallurgy and solid-wheel cattle-drawn cart technology the bovines could pull when not pulling plows (horses were hunted for meat and within two thousand years domestic horses were acquired, milked, ridden into battle and used to pull spoke-wheeled war chariots to aid expansion). The technology of the Proto-Indo-Europeans enabled them to both amass material goods and move them to become nomadic expansionists, expanding into a world of settled agrarians living in band-sized groups (typically not patriarchal) and remaining hunter-gatherers (also not patriarchal except where hunting was the basis of the biophysical economy). The Indo-European expansionists were initially stopped only by earlier high-intensity agriculture-based empire builders (e.g. Mesopotamian, Egyptians, Semites), though their more aggressive culture made steady inroads into these prior cultures even if not enough to replace their language (e.g. the Semitic religion was derived from Zoroastrianism, an Indo-European hierarchical priesthood dominated belief-based religion).

Will modern humans understand their predicament, renomalize... or die?

As the glaciers retreated 19,000 to 14,000 years ago, a new wave of migrants spread into Europe, and about 9,000 years ago, farmers from northwestern Anatolia moved in to spread, interbreed with and displace the hunter-gatherers. The third major migration began about 5,000 years ago when Indo-European herders swept in from the steppe north of the Black Sea in what is now Russia. Those Yamnaya pastoralists herded cattle and sheep, and some rode newly domesticated horses. Unlike the hunter-gatherers and agrarians, they were patriarchal and celebrated conquest which their livestock (especially horses) enabled. Little or no male hunter-gatherer/agrarian DNA survived, achieved by killing all males and breeding the women who persisted among the agrarians though their language and culture was largely replaced by the Indo-European invaders. Joseph Campbell found evidence of a goddess culture in the fragments of pre-Indo-European mythology. Descendants of the original populations served their overlords as a peasant, serf, commoner, or slave class (prey-like population to elite predator-like population). Prior to this, the Indo-European culture was not the norm as it is today worldwide.

Descent into Empire-building

10,000 BCE (11,950 BP, BP=Before Present=before 1950=BA, Before Acceleration, 1950 CE = start of the Great Acceleration and so 2016 = 66 AA or 66 years After Acceleration kicked in): Agriculture begins to transform human life in the Neolithic. Hunter-gatherer cultures tend to be matriarchal, as are Early and many Middle non-empire-building Neolithic societies whose mythologies (narratives) are Great Mother/goddess based as Joseph Campbell noted. The social systems tend towards the egalitarian and the economic system is based on sharing.

Early settlements in the Fertile Crescent were by foragers within high productivity wetlands having a high diversity of resources that were not subject to long-term storage. Settlements remained relatively small and egalitarian. For empire-building, later grain production was selected for as it could be taxed, stored, and stolen. Payment in grain served to create the early monetary culture we are all products of. "Civilization" could be viewed as a pathology enabled by grain production, but we products of civilization do not like that story. We remain for, and not "Against the Grain".

From small agricultural village beginnings, it took about four thousand years to transition to ever larger-scale chiefdoms and empire-building that was being selected for, which lead to city-states and then state-level complex societies or "true empires" such as we descendants of empire-builders might admire. A state-level complex society that does not engage in empire-building is possible, has been done (e.g. Tairona, Muisca), but without a means to make the world safe from empire-builders like us, then empire-building is selected for. Alternative is the proposed United Federation of Watersheds as without limits to conquest of Nature and other humans, manageable sized complex societies and their watershed-based life-support system appear to not persist for long (>1,000 years).

23,000 BA: Early Agriculture and the transition from hunting-gathering life may have begun 13,000 years earlier than its use became widespread enough to be noticeable in the archaeological record about 12,000 BA, which transformed human societies as hunter-gatherers could not compete with the high populations that agriculture supported.

Notes:

69,784 total empire years, 134 named empires = 520 years average lifespan.
Human ecology, when empowered by agriculture or by fossil fuels/industrial agriculture in an unmanaged commons, appears to follow a pulsing paradigm independent of changes in climate or variation in environmental resources or services. The repeating over-pulsing paradigm pattern is one of unmanaged growth exceeding sustainable limits unto overshoot followed by forced descent. A sustainable system, a managed commons—one managed to maintain a viable equilibrium between Man’s demands and Nature’s resources, would oscillate with environmental variations, but could avoid the boom and bust pattern.
Unsustainable system pulsing maximizes empower in the short term (as does cancerous growth), hence the empire-building pulses appear dramatic and often are. A managed system, such as a complex society that self-imposes limits, maximizes empower over a long-term period and so will be selected for if humans learn to understand and live with the planet properly as determined by Nature's laws.
1st millennium BA, 950 CE to 1950 CE, Holy Roman Empire to Soviet Empire, 31 complex societies, 6,967/31= 225 years average lifespan.
2nd millennium BA, 50 BCE to 950 CE, Imperial Roman Empire to Tuʻi Tonga Empire, 43 complex societies, 17,364/43= 404 years average lifespan.
3rd millennium BA, 1050 BCE to 50 BCE, Kingdom of Israel and Judah to Three Kingdoms of Korea, 41 complex societies, 20,969/41= 511 years average lifespan.
4th millennium BA, 2050 BCE to 1050 BCE, Middle Kingdom of Egypt to Zhou Empire, 13 complex societies, 7,957/13= 612 years average lifespan.
5th millennium BA, 3050 BCE to 2050 BCE, Stonehenge to Xia Dynasty, 9 complex societies, 9,077/9= 1,009 years average lifespan.
6th millennium BA, 4050 BCE to 3050 BCE, Uruk to Indus Valley Civilization, 4 complex societies, 6,800/4= 1,700 years average lifespan.
The Tairona lifespan shows the 200 year phase 1 pulse, 400 year phase 2 pulse, and the phase 3 steady-state economy that pulsed within boundaries to avoided overshoot while managing “sustainable development” as environmental resources (e.g. soil, forests) recovered following the degradation of prior unmanaged pulsing, until 1650 CE when the Spanish genocide and assimilation eliminated all but the Kogi. The nearby and later Muisca were also non-empire-builders whose managed steady-state society was conquered by the Spanish, but no remnant population survived.
The typical curve is a Seneca curve, a pulsing dynamic that better represents the rise and fall of empires than a line, as there are limits to the rate of growth but the rate of descent can be, often is, "rapid." "Increases are of sluggish growth, but the way to ruin is rapid." Letters to Lucilius #91, Lucius Annaeus Seneca, 64 CE. One definition of "civilization" is "a complex society large enough to leave ruins."
A modified Seneca curve is common as in descent an empire/kingdom/dynasty/state is increasingly subject to conquest by neighboring upstart empire-builders. The Indus Valley Civilization had no near-enough empires to allow conquest, so as it weakened, descent was forced by failure of environmental and human (commoner) services, which takes longer than conquest, but the outcome is similar. Rome wasn't conquered by barbarians at the height of its power, but as Orwell noted, the "fall" part (that may involve conquest or revolution) is usually the "kicking in of a rotten door." Conquest and revolution may be incidental. The American Revolution was to see who would take a continent, while more often revolt and civil war is merely to see who will (for a time) inherit the rubble.
Alternative to collapse/conquest/revolt is being subsumed into an emerging dynamic, an if-you-can't-beat'm-join'm option. The Portuguese, Spanish, British, Russian, American, French, Japanese, and Soviet empires/economies were subsumed into the emerging global Euro-Sino Empire of commerce that won over nation-state political control SYSTEMs, especially following WWII, because that was what was selected for along with the spread of democracy (e.g. The Democratic People's Republic of Korea). The Sino/SE Asian region had been a land for the taking by Portuguese, Spanish, British, Russian, American, French and Japanese empire-builders, but China has ended up, by embracing (as Japan had before it) the Euro Empire of commerce. China now consumes half of the planet's coal burned per year, along with many other resources, to manufacture products for the world's consumers (for a time), hence the Euro-Sino. After the Sino region climaxes, there is nowhere else to go but up, as there is a solar system for the taking, so to continue growing we'll have to build a Dyson Sphere before spreading to other solar systems to turn the galaxy into an infrared emitter. Or maybe we won't.
Another view of longivity over time; from The vulnerability of aging states: A survival analysis across premodern societies.

13050–9550 BCE (15,000–11,500 BA, a 3,500 year period): Natufian culture was a Late Epipaleolithic archaeological culture of a hunter-gatherer form of civilization in the Levant that was displaced by agrarian pastoral cultures, a different form of civilization. They were preceded by the Kebaran culture (18,000 to 10,500 BCE) who used the bow and arrow, and had dogs, who were preceded by the Levantine Aurignacian culture (35,000-29,000 BA) who were preceded by the Emiran culture who were preceded by the Ahmarian culture (46,000–42,000 BA) who were preceded by the Boker Tachtit culture (50,000 BA) who as 'Man the Hunter' expansionists had come out of Africa to replace the Neanderthals (60,000 BA) in the area who had replaced the first Homo sapiens sapiens in the area (90,000 BA) who had replaced the Mousterians (160,000 to 40,000 BA) who evolved from Homo sapiens (heidelbergensis) from whose African branch H. sapiens sapiens evolved about 350,000 to 400,000 BA. H. s. heidelbergensis occupied the Levant 700,000 years ago after evolving from Homo erectus ergaster in Africa about 1.3 million years ago. H. s. heidelbergensis, on leaving Africa, displaced H. erectus, the first hominin in the Levant, who had come to the Levant about 2 million years ago.

In chronological order:

We evolved from Homo erectus ergaster, the African form of H. erectus (the first hominin to leave Africa 2 million years ago), about 1.3 million years ago to become Homo sapiens (aka H. sapiens heidelbergensis).
As H. sapiens (heidelbergensis) we left Africa slowly about 700k years ago as adaptive K-strategists to gradually displace H. erectus in the Levant.
While H. sapiens adapted in Europe to become H. sapiens neanderthalensis and in Asia to become H. sapiens. denisova, we evolved from the East African population of Heidelbergensis (Homo sapiens) about 375k years ago to become a subspecies, H. sapiens sapiens, the last hominin standing.
As H. s. sapiens we had slowly left Africa about 150k years ago and were living in the Levant about 90k years ago as adaptive K-strategists who had displaced H. sapiens neanderthalensis in the Levant.
H. sapiens neanderthalensis, as adaptive K-strategists, pushed H. s. sapiens back out of the Levant about 60k years ago.
An expansionist form of H. s. sapiens evolved in East Africa 60k to 50k years ago to rapidly spread to the Levant about 50k years ago (and globally) as a technology and culturally enabled aggressive invasive species to displace H. s. neanderthalensis in the Levant, elsewhere, and all other hominins on the planet (and many other forms of megafauna) including the non-expansionist forms of Homo sapiens sapiens with the exception of the last true humans, the San, Hadza, and Pygmy in Africa.
Based on behavioral differences, we expansionist moderns could be considered a new subspecies, H. sapiens insapient who has prospered greatly for a time (50k+ years), but expansion is only for a time (likely ending this century in a Great Selection).
Among early agrarian/pastoral expansionists who had displaced Man the Hunter expansionists in the Levant about 11k years ago (on their way back to Africa from the Fertile Crescent region), the to-the-north-and-west Indo-European cattle expansion began 7k-9k years ago, reaching the Levant about 3.5k years ago while the Austronesian/Polynesian expansion, beginning about 5k years ago, completed the taking of the planet, ending in Zealandia bout 500 years ago while the Indo-Europeans were taking the planet from prior takers (expansionists).

Pick any region on the planet and the prehistory will not differ in kind from that of the Levant. Hominins left Africa about two million years ago, and Homo sapiens 120k to 185k years ago. All hominins and H. sapiens out of Africa were replaced/displaced by the second out of Africa wave of H. sapiens starting 50k to 60k years ago. They were aggressive (successful) expansionists. All modern humans outside of Africa are descended from a small population of expansionists who left Africa by crossing the Red Sea to spread east to Australia, and north through the Levant to Europe and Asia, and on to the Americas. The east spreading group eventually occupied the Pacific islands (Polynesian expansion). The north then west spreading population meet the east spreading population in 1021 CE when Indo-Europeans sailed across the Atlantic to build a settlement on Newfoundland occupied by those who had spread across Asia and the Americas.

The Natufian culture was unusual in that it supported a sedentary or semi-sedentary population (90 settlements have been excavated) even before the introduction of agriculture. Natufians exploited wild cereals and hunted animals, and may have engaged in early low-intensity agriculture (planting of seeds). Archaeogenetic analysis has revealed derivation of later (Neolithic to Bronze Age) Levantines primarily from Natufians, besides substantial admixture from Chalcolithic Anatolians from the northern part of the Fertile Crescent. At the time, the region was woodlands. DNA analysis of Natufian skeletal remains (2016) found that the specimens were a mix of 50% Basal Eurasian ancestral component and 50% Western Eurasian Unknown Hunter Gatherer (UHG) population related to European Western Hunter-Gatherers.

By 8500–7500 BCE, the Pre-Pottery Neolithic A (PPNA) culture developed out of the earlier local tradition of Natufian (dwelling in round houses), and building the first defensive site at Tell es-Sultan (ancient Jericho, guarding a valuable fresh water spring). This was replaced in 7500 BCE by Pre-Pottery Neolithic B (PPNB), dwelling in square houses, coming from Northern Syria and the Euphrates bend. During the period of 8500–7500 BCE, another hunter-gatherer group, showing clear affinities with the cultures of Egypt, was in Sinai. This Harifian culture may have adopted the use of pottery from the Isnan culture and Helwan culture of Egypt (which lasted from 9000 to 4500 BCE), and subsequently fused with elements from the PPNB culture during the climatic crisis of 6000 BCE to form a Syro-Arabian pastoral technocomplex [goat herding], which saw the spread of the first Nomadic pastoralists in the Ancient Near East. These extended southwards along the Red Sea coast and penetrated the Arabian bifacial cultures, which became progressively more Neolithic and pastoral, and extending north and eastwards, to lay the foundations for the tent-dwelling Martu and Akkadian peoples of Mesopotamia. In the Amuq valley of Syria, PPNB culture seems to have survived, influencing further cultural developments further south. Nomadic elements fused with PPNB to form the Minhata Culture and Yarmukian Culture, which were to spread southwards, beginning the development of the classic mixed farming Mediterranean culture, and from 5600 BCE were associated with the Ghassulian culture of the region, the first Chalcolithic [copper age] culture of the Levant. This period also witnessed the development of megalithic structures, which continued into the Bronze Age.

--------------------------------------------------------

As an artful prelude to the next 11 millennia, watch This Land Is Mine (A brief history of the land called Israel/Palestine/Canaan/the Levant;.watch video, but scroll down first to see who the players are), an animated short by Nina Paley.

The first character to strut their stuff is ‘Early Man’, but from the above, with a focus on the Levant, the first three and a half minutes should feature competitive displacement, no slaughter implied, starting with Homo erectus, displaced by Heidelbergensis, then Neanderthal, then H. sapiens sapiens pre-expansionist form of us that displaced Neanderthal, who 60k years ago competitively displaces us.

But then about 50k years ago the expansionist, invasive species form of us spread out of Africa to and beyond the Levant to take it and the planet by conquest, typically involving killing the adult males and breeding the females whose offspring learn the conqueror's language and expansionist (patriarchal) culture, and the expansion by conquest continues for 50k years within the Levant as competing groups kill adult males and breed the females (not shown in video) and worldwide until Planet A has been taken.

Beyond the Early Man character in the video, all of the characters contending are from the last 4k years of an area having a 2 million year history of hominin habitation, and so they should get only the last second of the video, or if their predecessors where given equal time, the video would be 21 hours long.

We expansionist humans, we Anthropocene humans, are time blind. We barely can notice the last 4k years of history in the Levant, while being blind to 99.8% of the regions human past. Welcome to the Anthropocene, which proximally started about 50k years ago.

--------------------------------------------------------

9130–7370 BCE (11,080-9320 BA, a 1,760 year period): Göbekli Tepe and older sister site Karahan Tepe (10550 BCE, 12,500 BA) are archaeological sites in the Southeastern Anatolia Region of modern-day Turkey featuring the earliest known massive monument building that was begun by hunter-gatherer nomads. As they were not united by force of arms, and the site is for ceremonial use on special occasions when the nomadic bands meet up, the site is evidence for the first Empire of Belief that enabled super-tribalism, the exceeding of Dunbar's number, created by a priest/storyteller whose narrative spreads to the storytellers in other bands who come to tell the viral tale.

Believing priests, former storytellers, turn humans into true believers and thereby prosper. The High Priestess or Priest can direct monument building during the regional gathering to hear the Word from on High. Priests and/or priestesses are elites lording over the minds of commoners, teaching them to believe in belief from early childhood. Elite religious hierarchies form before military empires are made possible by agricultural surplus. When chiefs come to rule chiefdoms, the priests are natural fellow elites who tend to support the armed empire builders by mixing the political this-worldly narrative with their own other-worldly religious narrative.

7500-5700 BCE (1,800 years, 9,450-7,650 BA): Çatalhöyük, a proto-city settlement in southern Anatolia, based on early agriculture. Peak development 7000 BCE with 18 successive layers of buildings signifying various stages of the settlement and long decline as there were no outlying empire-builders to conquer the region. The failure of the agricultural production system may have been enabled by the adoption of the newly invented plow that enabled overproduction and increase in soil erosion.

6500–3800 BCE (2,700 years, 8450-5750 BA): The Ubaid period is a prehistoric period of early state level empire-building among Mesopotamian agriculturalists living in complex societies above the chiefdom or cty-state level of empire-building. In South Mesopotamia the period is the earliest known period on the alluvial plain. In North Mesopotamia the period runs only between about 5300 and 4300 BCE (a 1,000 year northern pulse). Agriculture allows for chiefdoms, trial runs for later more expansive empire-building that favor alpha male chiefs and warriors along with their verbal defenders.

6500-5400 BCE (1100 years, 8450-7350 BA): The Siberian taiga culture developed the first fortified settlements based on fish, elk, waterfowl, and reindeer harvests stored by smoking and in permafrost. The lived in pit houses surrounded by forest near rivers. At some point they came to view each other as a needed resource for the taking. Descent to local extinction.

5950-4850 BCE (1100 years, 7900-6800 BA): The early Korean hunter-gatherer culture formed long-term settlements on the coast by exploiting abundant marine resourses, for a time.

5900-2500 BCE (3400 years, 7850-4450 BA): The early Malta inhabitants came from Sicily (inhabited about 10k BCE) about 5900 BCE, 80 km (50 mi) by sea to the north. The settlers were renormalizing Neolithic hunter-forager-farmers whose expansionist ancestors had left Africa 50k years earlier to take Eurasia from prior hominins, The renormalizing Maltese persisted for 1900 years before transitioning to a complex society that proved itself to be overcomplex after 1500 years, 60 generations, of denormalization (if renormalizing is possible for us, could it be achieved in less time?). The islands of Malta are nearly twice the area of Easter Island, and were, like Rapa Nui, well forested when the first humans came ashore with crops and livestock. The dwarf hippos, giant swans and dwarf elephants were soon extinct. From 4000 BCE to 2500 BCE, complex society arose, megalithic temples with a fertility goddess theme were built prior to Egyptian pyramids. The Ġgantija megalithic temples [e.g. below and take a walking tour] built 3600-2500 BCE are the world's second oldest existing man made religious structures after Göbekli Tepe/Karahan Tepe.

A human ecology view suggests that the first human inhabitants, as an invasive species, may have caused megafauna extinctions as usual (but correlation may not be causation), but transitioned to maintaining a stable population as K-strategists bumping up against the island's carrying capacity for about 1900 years (unlike Easter Islanders) by living in small band size (20 to 50) groups as hunters and low-intensity forager-gardeners who do not build monuments, likely matriarchal. These early Maltese had crops and livestock, but may have lived like Calhoun's first rats, wild rats who maintained a stable population regulated by overdensity stress, and so did not overpopulate their habitat. They could have, but did not, overshoot carrying capacity by deforesting the island for short-term maximizing of agricultural productivity, a dynamic that requires elites and commoners (i.e. complex society lacking Mothers, a band-sized population's control system replaced in complex societies). Later waves of migrants from Sicily likely lead to crowded overexploitation of island resources (e.g. forests and soils).

By about 4000 BCE the population was large enough to form unsustainable complex clan societies that select for hierarchies, as at Göbekli Tepe, lead by priests/priestesses with an interest in temple building. The first modest temple building began about 4000 BCE and had become widespread and immodest by 3500 BCE, climaxing some time after 3000 BCE as prosperity gave way to multiple economic and environmental stressors.

Their complex society had no regional enemies and empire building was confined to remorseless expansion of ever increasing extent and intensity empowered by unsustainable farming, however slow the pace. It was in the short-term self interest of island elites (as predator population exploiting belief-based cognition) to pressure commoners (as true believing prey population) to produce more offerings to provision the temple (and keepers of the temple). There was, near the end, a great acceleration in prosperous (not remotely sustainable) development.

The population peaked some time after 3000 BCE with temple building reaching a feverish pitch in the final phases of religious control system activity about 2500 BCE when complex society collapsed throughout the islands (all temple building ends and not because everybody decided to move back to Sicily). Expansion by conquest was not possible, even if there had been a warrior class, as was leaving a deforested island by wooden ships. The peak population before die-off is unknown, but would have been in the tens of thousands. Fertility cults, priestesses, and perhaps even Mother, gave way to death cults likely dominated by priests.

By 2000 BCE the island was, or nearly was, uninhabited/uninhabitable, i.e. had experienced an Easter Island deforestation/overshoot/depopulation event caused by the slow emergence of 'civilization' pathology. Like rats in a Calhoun experiment, they seem to have undergone a self-extinction event. [This is of interest as humans are now doing an overshoot event globally for the first time, and though a remnant population is likely, they may fail to reboot to live in viable societies, as happened with the Indus Valley Civilization. A near extinction event, if not extinction, of humans is of concern, and if a remnant population passes through the bottleneck, will it ever recover lost functionality if no functional humans also pass through it? If there are still humans on the planet in five thousand years, what sort of humans will they be?]

Malta was eventually resettled by Bronze Age warriors, a patriarchal culture who built the fortified settlement of Borg in-Nadur about 1500 BCE after partial environmental restoration/recovery of island resources (in one sense or another, we are all descendants of Borg). If there was a remnant population of prior inhabitants, they had lost or failed to pass on any elements of their culture, i.e. there was also a loss of information event approaching or equaling 100 percent as usual. If they had developed a writing system, no literate temple builders survived the overshoot and collapse event.

Today Malta has a population of over 500k. The agriculture, with less than 600 mm (24 in,) of mostly winter rain, is modern agribusiness/irrigation production, dependent on fossil fuel inputs. Transitioning back to sustainable low intensity swidden agriculture would support far less than the 4,000 people in prehistoric times prior to the extensive environmental degradation of today that began with over exploitation 4000-2500 BCE. If (when) the planes stop landing and ferries stop bringing tourists, and ships stop importing supplies, Malta will undergo a 99+ percent depopulation event even if no one votes for it.

The end of modern techno-industrial (MTI) production and consumption is the condition that will come anyway. If modern Malta ended all imports this year, 99+ percent of the population would leave the islands (mostly peacefully with enthusiasm) to live elsewhere until they and/or their descendants couldn't. I would advise the people of Malta having foresight intelligence to "seek out the condition now that will come anyway" [H.T. Odum]. I would also advise the frog in the pot of warming water to get out, even though it feels so good (for a time).

But pick any other place on the planet..., the same advice would be in the resident's long term best interest. MTIed (modern techno-industrialized) humans may consider Malta a better example of what happens when a culture overshoots environmental productivity than Easter Island or St. Matthew Island. Those living in Malta now, lacking foresight intelligence, will not act because they cannot.

We are all living on a Malta the size of a planet, but we will leave more impressive ruins. We are now, for a time, a 'superorganism'. The basic unit of society is not a band of related mothers. The basic unit of modern techno-industrial society is the corporation, an amoeboid like dissipative structure that must keep on keeping on (to 'for a beautiful moment in time' create a lot of value for shareholders) until it can't. We who are dependent on it, must serve it until we can't. And those who are not too dependent on it, who do not believe in it, may be too few (<0.01%, including dependents, maybe 50 at most on Malta) to matter.

Note to posterity: sorry about that.

From Malta past to present, the question of what 50 Maltese might do leads to The Malta Solution that is unthinkable to MTI humans, almost as unthinkable as thinking that we are not just animals, but dysfunctional animals whose only hope is to renormalize as mere animals, i.e. stand down from our hubris heights. The amygdalas of all MTI humans react to the obvious truth of their being by shouting in unanimous consensus: NO! The solution thus becomes viewed as worse than going extinct. Lord Man be gone.

5800-3000 BCE BCE (3000 years, 7750-4750 BA): Cucuteni–Trypillia culture,one of the first Old European cultures invaded by Indo-Europeans. A Neolithic–Chalcolithic archaeological (Linear Pottery) culture of shifting agriculture and settlements mostly self-sufficient with very little need for trade and with low levels of social stratification (inequality), but no evidence they were able to limit their expansion.

Early period Cucuteni pre-Indo-European expansion (5800-4050 BCE) inhabitants were agrarians with cattle, sheep, goats from Fertile Crescent region having a matrifocal culture. Early homes were pit-houses, then wood and clay-daub structures.

Middle period (5000–3500 BC) was one of expansion and population growth as more land was put under cultivation/grazing.

Late period (3500–3000 BC). Towards the end, 600-700 small settlements were abandoned as they would have no defense against a greater number of raiders on horses, and the culture/adult male population was replaced by Indo-Europeans with horses who imposed their language and cultural norms (and bred the females). The Old Europeans had displaced the partially renormalized hunter-gather indigenous expansionists while rarely interbreeding with or adopting their orphans.

Some giant-settlements or mega-sites (>150 hectares/370 acres and of more than 1000 houses each) developed, lasting up to 150 years, the largest (Talianki) reaching 340 ha (840 acres). Settlements average lifespan was 60 to 80 years up to 150 years for mega-sites. One site had 13 levels of habitation between periods of abandonment.

Early Indo-Europeans may have domesticated cattle 9 thousand years ago on the northern margins of the Fertile Crescent, and prior to developing wheeled cart technology, slowly moved north into the region of today's Moldova and covering substantial parts of western Ukraine and northeastern Romania. The majority of Cucuteni–Trypillia settlements were of small size (<150), high density (spaced 3 to 4 kilometers [1.9-2.5 miles] apart), concentrated mainly in the Siret, Prut and Dniester river valleys. During its middle phase (c. 4000 to 3500 BC), populations belonging to the Cucuteni–Trypillia culture built the largest settlements in Neolithic Europe, some of which contained as many as three thousand structures (3.4 burnt:1 unburnt) and were possibly inhabited by estimated >12,000 people (7-15 people/structure) at Maidanetske assuming all structures were occupied (settlements only lasted about 150 years and if houses lasted 30 years, they may have been burnt and a new one build near it, so total population may have been 5000).

Average house size of 77m² (829 ft sq) known space requirements for persons in sedentary societies if 5-15m²/person in a house, averaging 6.97m²/person (75 sq ft/person, 10 persons/household) in prosperous settled communities.

There is no evidence of an Indo-European Kurgan blitzkrieg (that took 5k years to perfect). The taking of the Cucuteni–Trypillia region may have taken a century or two to complete as the Indo-European conquest culture learned what works and how to do the vin, vidi, vici thing faster. That 64% of today's European males descend from just three Info-Eurpean paternal ancestors is "proof" of their metastatic superiority at they would view it—rapid growth also being the ideology of the cancer cell.

With a better understanding of agroecology, however, the Trypillia culture of shifting agriculture was sustainable at a low density, as is Swidden agriculture in the tropics. But recovering r-cultures are not renormalized K-cultures able to know their limits. The Trypillians were no match to the Indo-European aggressive expansionism on horse with bronze weapons.

At one point the Old Europeans out numbered the agressive expansionists 100:1 or greater. If they had recognized the existential threat of the Indo-Europeans (most of you reading this), and each community of 20 to 50 sent 1-2 Guardians to the east to confront them when they first started their expansion about 6000 BCE, then 100k vs 1k warriors would likely have had a different outcome, but likely waiting until 3000 BCE was too late. As an outcome, our global condition of overshoot may be game over for the last hominin standing.

5250-4500 BCE (750 years, 7200-6450 BA): The Hamangia culture, to the east of the Cucuteni–Trypillia culture, was late Neolithic settlements having mixed horticultural economies between the Danube and the Black Sea that was absorbed/conquered by the expanding Indo-Europeans making them the first Old European complex society to be conquered by another empire-building culture. The Hamangians celebrated the Goddess, but those who 'displaced' them did not. Hamangian cultural links with Anatolia suggest that it was the result of a recent settlement by people from Anatolia, unlike the neighboring cultures, whom the Hamangians displaced/conquered.

5200 BCE (7150 BA): The Indo-European expansion of language and culture that selects for rapid empire-building spread in several stages from the Pontic steppes into western Europe, central Asia and India. This process started with the introduction of cattle at the Eurasian steppes, which led to the rise of a new culture, to a kind of cowboy culture. Between 5000 and 2000 BCE, they spread-out with their cattle first and later horses over the Pontic steppes, and outside into Europe and Asia. Use of force was involved in displacing hunter-gatherers, but the expansion was based on cattle as the basis of the economic system that empowered them. Much as plant-based agriculture supported empires in Mesopotamia, Egypt, India, China, coastal Andes, and Mesoamerica, animal-based agriculture supported the spread of the Indo-Europeans. The first Indo-European speakers to build empire based on military force are the Hittites who had spread into central Turkey fighting with chariots and iron weapons. Linguistics has allowed the reliable reconstruction of a large number of words relating to kinship relations. These all agree in exhibiting a patriarchal, patrilocal and patrilineal social fabric that opposes the Paleolithic hunter-gatherer and Early and Middle Neolithic egalitarian norms. In patriarchies women are exogamous, joining their husband's (their overlord's) family. The mythology focuses on supreme beings, on really Big Gods with strongly alpha male natures who are intolerant of matriarchal narratives. Empire-building favors patriarchal values and the conquered become patriarchal. Wanting to be an alpha male is a biological atavism as is the capacity to fear and submit to alpha male elites, real or imagined, that goes with empire-building.

4000–3100 BCE (900 years, 5950-5050 BA): The Uruk period existed in the protohistoric Early Bronze Age period in the history of Mesopotamia and was the first state-level overcomplex, stratified, hierarchical society with an appreciable division of labor (weavers, artisans, priests, prostitutes, metalworkers, clerks, soldiers, cultivators) supported by taxes collected in the form of grain and labor to serve elite interests (priests and potentates). War was needed to acquire resources/slaves from outliers as there was as yet no nearby competing empire builders to threaten their taking. This period saw the emergence of urban life in Mesopotamia. It was followed by the Sumerian civilization. The late Uruk period (34th to 32nd centuries) saw the gradual emergence of the cuneiform script and corresponds to the Early Bronze Age; it may also be called the Protoliterate period.

4000–3800 BCE (200 years, 5950-5750 BA): Nebelivka, located in Ukraine, north of Black Sea, is the site of an ancient mega-settlement likely occupied for a part of each year as a ritual, ceremonial or defensive gathering place. Artefacts include female or Venus figurines. Perhaps 3,000 to 4,000 people inhabited Nebelivka for around one month each year. During that time, people who assembled at the megasite made new contacts, shared knowledge and goods, and conducted communal activities such as house building and burning. Perhaps 100 to 150 guardians lived at and maintained Nebelivka year-round. That bands of forager-hunters periodically meet up to exchange genes and memes was the hominid norm for millions of years. That the gatherings were so large, enabled by large wild grain harvest/storage then planted crops, left ruins from lithic construction, and allowed a permanent population to occupy the site, was not.

3900–2300 BCE (1600 years, 5850-4250 BA): Sannai Maruyama site in Japan, abundant marine life supported long term settlements of hunter-gatherers, for a time. Rapid growth in complexity to climax followed by decline to local extinction.

3850–3700 BCE (150 years, 5800-5650 BA): Talianki, is an archaeological site near the village of the same name in Ukraine, about 34 km walking distance from Nebelivka, currently the largest known settlement of the time in Neolithic Europe before the coming of the Indo-Europeans. At its height, Talianki could have been occupied by over 6k-15k inhabitants supported by cereal agriculture. Early settlements by matriarchal cultures followed egalitarian norms of the forager-hunters who added gardening to their culture until overcomplexity selected for hierarchy/inequality and high intensity farming over the centuries to support developing elite populations initially of priestesses/priests. Conquest by patriarchal Indo-Europeans tended to displace such cultures across Europe and Central Asia, then worldwide.

3650–1450 BCE (2,200 years, 5,600-3,400 BA): Minoan civilization (mature period 2000–1450 BCE) was an Aegean Bronze Age civilization that arose on the island of Crete and other Aegean islands. Homer recorded that Crete once had 90 cities. The Minoan writing system remains unreadable, so 100% of information recorded in it was lost.

3500–1800 BCE (1,700 years, 5450-3750 BA): The Norte Chico civilization (also Caral or Caral-Supe civilization) was a complex pre-Columbian society that included as many as 30 major population centers in what is now the Norte Chico region of north-central coastal Peru. Since the early 21st century, it has been established as the oldest known civilization in the Americas.

3500–2500 BCE (1,000 years, 5450-4550 BA): Two Ġgantija temples on the Mediterranean island of Gozo, Malta, are late Neolithic, which makes them the world's second oldest existing man made religious structures after Göbekli Tepe. The temples are elements of a ceremonial site with numerous figurines and statues associated with fertility rites.

c. 3400–2900 BCE (500 years, 5350-4850 BA): Oued Beht, Morocco, a recently (2024) reported farming culture, a a mixed population ancestry of local hunter-gatherers, Neolithic Iberian farmers and Saharan pastoralists, the earliest and largest agricultural complex in Africa beyond the Nile corridor, that cultivated barley, wheat, peas, pistachios and olives, and grazed sheep, goats, pigs and cattle with reliance on livestock on an area of 9–10ha (25 acres). The experiment in civilization building was brief for this time period. Agropastoralist practices likely not sustainable, part of the degrading of North Africa by livestock history.

3400–2250 BCE (1,200 years, 5350-4450 BA): The Liangzhu culture was the last Neolithic jade culture in the Yangtze River Delta of China. The culture was highly stratified, as jade, silk, ivory and lacquer artifacts were found exclusively in elite burials, while pottery was more commonly found in the burial plots of poorer individuals. This division of class indicates that the Liangzhu period was an early state, symbolized by the clear distinction drawn between social classes in funeral structures.

3300–3000 BCE (300 years, 5250-4950 BA): Start of Bronze Age. Weapons "improve," which facilitates empire-building. Technology becomes as a vat of wine to an alcoholic. Both feel good but have lamentable side effects. Imagine giving a hundred five year olds a machete and turning them loose on your Mother's Garden unsupervised for five hours. They would lay waste to the Garden, injure one another, and there would likely be fatalities—the story of Man's last five thousand years in the Great Mother's Garden Earth.

3300–1300 BCE (2,000 years, 5250-3250 BA): The Indus Valley Civilization (IVC) was a Bronze Age civilization (mature period 2600–1600 BCE) mainly in northwest South Asia, extending from what today is northeast Afghanistan to Pakistan and northwest India. Along with ancient Egypt and Mesopotamia it was one of three early civilizations of the Old World, and of the three the most widespread. It flourished in the basins of the Indus River and along a system of perennial, mostly monsoon-fed, rivers. The late Harappan phase, weakened but with no outside force to conquer it, witnessed large scale de-urbanization, population decrease, abandonment of many established settlements, lack of basic amenities, interpersonal violence and disappearance of the Harappan script (loss of two thousand years of information as what writing survived is unreadable–no literate Harappans survived or left a Rosetta book). Indo-European Aryans moved in the area to become the Brahmans of India.

Per Wikipedia: 'Around 1900 BCE signs of a gradual decline began to emerge, and by around 1700 BCE most of the cities had been abandoned. Recent examination of human skeletons from the site of Harappa has demonstrated that the end of the Indus civilisation saw an increase in inter-personal violence and in infectious diseases like leprosy and tuberculosis. According to historian Upinder Singh, "the general picture presented by the late Harappan phase is one of a breakdown of urban networks and an expansion of rural ones."... there was a general decrease of long-distance trade.... Stone sculptures were deliberately vandalised, valuables were sometimes concealed in hoards, suggesting unrest, and the corpses of animals and even humans were left unburied in the streets and in abandoned buildings. During the later half of the 2nd millennium BCE [1500–1300 BCE], most of the post-urban Late Harappan settlements were abandoned altogether. Subsequent material culture was typically characterised by temporary occupation, "the campsites of a population which was nomadic and mainly pastoralist" and which used "crude handmade pottery."'

3000–2000 BCE (1,000 years, 4950-3950 BA): Stonehenge is a prehistoric monument in England. Stonehenge's ring of standing stones are set within earthworks in the middle of the most dense complex of Neolithic and Bronze Age monuments in England. The ceremonial site, like that of Göbekli Tepe, suggests an early empire of belief.

2700 – 539 BCE (2,161 years, 4650-2489 BA): Elam Empire western Iran region. Preceded by Proto-Elamite: c. 3200 – c. 2700 BCE period of small scale empire-building east of the Tigris and Euphrates alluvial plains, and divided into three periods: Old Elamite period: c. 2700 – c. 1500 BCE, Middle Elamite period: c. 1500 – c. 1100 BC (Anzanite Dynasty until the Babylonian invasion), Neo-Elamite period: c. 1100 – 540 BCE (characterized Assyrian and Median influence). Elam traded with the Indus Valley Civilization and the cities of Mesopotamia.

2686–2181 BCE (505 years, 4636-4131 BA): Egyptian Nile Empire, Ancient Egypt, Old Kingdom. The earliest known large-scale empire appears in Egypt when King Narmer of the Upper Valley conquered the lower Valley and laid the foundations for the Old Kingdom. Empire-building requires warriors and an agricultural surplus to support them, as well as the elites who command them. Alpha males favoring patriarchy prosper, though some empire-builders are matriarchal. New narratives as told by priests and the intelligentcia develop to normalize male and/or female elite dominance, inequality, and empire-building.

2500-1500 BCE (1,000 years, 4450-3450 BA): Kerma Kingdom. A sizable, populous empire in Upper Egypt and northern Sudan region rivaling Ancient Egypt. Around 1500 BCE, it was absorbed into the New Kingdom of Egypt, but rebellions continued for centuries.

2500–539 BCE (1,961 years, 4450-2489 BA): Phoenicia, a thalassocratic seaborne empire, ancient Semitic-speaking Mediterranean civilization that originated in the Levant, specifically Lebanon, in the west of the Fertile Crescent. The high point of Phoenician culture and sea power is usually placed c. 1200–800 BCE. Persian King Cyrus the Great conquered Phoenicia in 539 BCE.

2400–1200 BCE (1200 years, 4350-3150 BA): Hurrian Kingdom of Urkesh, emerged around the city of Urkesh in modern Iraq, during the third millennium BC. It was a major stop on trade routes between Anatolia, Syria, Mesopotamia, and the Mediterranean. Disassociated during the Late Bronze Age collapse.

2400–1900 BCE (500 years, 4350-3850 BA): Bactria–Margiana Archaeological Complex (short BMAC), also known as the Oxus civilization, numerous monumental structures in many sites, fortified by impressive walls and gates. Reports on the BMAC were mostly confined to Soviet journals beginning with excavations in the late 1970s, not well known in the West.

2025–609 BCE (1,416 years, 3975-2559 BA): Assyria, a major Mesopotamian East Semitic-speaking kingdom and empire of the ancient Near East, existed as an independent state from perhaps as early as the 25th century BCE, until its collapse between 612 BCE and 599 BCE, spanning the mid to Early Bronze Age through to the late Iron Age. Weakened by resource depletion, the fading empire was conquered by upstart empire builders on the outskirts.

2334–2154 BCE (180 years, 4284-4104 BA): The Akkadian Empire, established by Sargon of Akkad 24th century BCE, was an early all-Mesopotamian empire. Collapse followed by a 42 year "Dark Age" of famine and chaos with no prominent imperial authority until the Third Dynasty of Ur.

2112–2004 BCE (108 years, 4062-3954 BA): Third Dynasty of Ur. The last Sumerian Dynasty which came to preeminent power in Mesopotamia.

2070-1600 BCE (470 years, 4020-3550 BA): Xia Dynasty. The first dynasty in traditional Chinese history. Preceded by small scale empire-building. With size, large construction projects attempted to control flooding of Yellow River and eventually succeeded increasing agricultural output. Corruption lead to overthrow, creating the Shang Dynasty.

2050-1710 BCE (340 years, 4000-3660 BA): Middle Kingdom of Egypt. After the collapse of the Old Kingdom, Egypt entered a period of weak Pharaonic power and decentralization called the First Intermediate Period. Towards the end of this period, two rival dynasties fought for power over the entire country leading to the Middle Kingdom.

1900 BCE – 900 CE (2800 years, 3850 – 1050 BA): The Izapa, a pre-Columbian civilization on the Pacific coast plain of Central America, a huge temple centre near modern Tapachula, Chiapas. Its approximately 80 pyramidal mounds were built from earth and clay faced with river boulders. Climax cities 100 BCE– 400 CE, Terminal Formative (100 BCE – 250 CE), Early Classic (250–500 CE), Middle Classic (500–700 CE), Late Classic (700–900 CE). PostClassic period extending from A.D. 900–1521 CE. No conquest of the weakened empire until the Spanish take over of the remnant population living amid ruins. Geographically between Olmec (1500– 400 BCE) and Mayan Classic period of monument building (250 – 900 CE), Collapse of one overcomplex society leads to mass migration that can trigger the collapse of nearby complex societies as may have happened about 900 CE.

1900–1500 BCE (400 years, 3850-3450 BA): The Erlitou culture is an early Bronze Age urban society and first recorded dynasty of China. Considered the first state level society of East Asia. The earliest bronze knife dated 3000 BCE and the Yellow River was used for irrigation around 2205 BCE.

1894–1595 BCE (300 years, 3844-3545 BA): Old Babylon Empire was an ancient Akkadian-speaking state and cultural region based in central-southern Mesopotamia (present-day Iraq). Babylon greatly expanded during the reign of Hammurabi in the first half of the 18th century BCE. Babylon was then attacked by the Indo-European speaking and Asia Minor based Hittite Empire in 1595 BCE. Shamshu-Ditana was overthrown following the "sack of Babylon" by the Hittite king Mursili I. The Hittites did not remain for long.

1700–1027 BCE (673 years, 3650-1977 BA): In China rose the Shang Empire which conquered the Xia Dynasty to eventually weaken and fall to conquest by nearby empire builders.

1600 — c. 1260 BCE, (340 years, 3500-3160 BA): Mitanni Kingdom, a Hurrian-speaking state in northern Syria and southeast Anatolia (modern-day Turkey) with Indo-Aryan linguistic and political influences. Since no histories, royal annals or chronicles have yet been found in its excavated sites, knowledge about Mitanni is sparse compared to the other powers in the area, and dependent on what its neighbors commented in their texts.

1600–1180 BCE (420 years, 3500-3130 BA): The Hittites were an Ancient Anatolian people who established an empire centered on Hattusa in north-central Anatolia who spread, using horse and chariot tactics, and they were early iron workers. This empire reached its height during the mid-14th century BCE, when it encompassed an area that included most of Asia Minor as well as parts of the northern Levant and Upper Mesopotamia. The empire came to an end during the Bronze Age collapse, splintering into several independent "Neo-Hittite" city-states, some of which survived until the 8th century BCE (700 BCE).

1600–1100 BCE (500 years, 3500-3050 BA): Mycenaean Greece (or Mycenaean civilization) was the last phase of the Bronze Age in Ancient Greece. As with the later Roman Empire, the collapse of Mycenaean Greece was followed by a Dark Age which lacked a Holy Roman Empire type of institution to preserve some level of literacy. Mycenaeans developed Linear A script, which remains undeciphered, and Linear B script which the Classical Greeks came to base their written language on. During the Dark Age, information was passed on orally. Classical Greek thought was based on Homer's Dark Age narratives as they were eventually written down before being lost.

1595–1155 BCE (440 years, 3545-3105 BA): Middle Babylonian period, also known as the Kassite period, assumed political control over the region. Akkadian-speaking, their language was the lingua-franca of the Late Bronze Age societies of the eastern Mediterranean.

1570–1070 BCE (400 years, 3470-3020 BA): New Kingdom of Ancient Egypt, ruled by Thutmose III, was ancient Africa's major force upon incorporating Nubia and the ancient city-states of the Levant.

1500-500 BCE (1,000 years, 3400-2400 BA): Vedic Civilization. The period in the history of the northern Indian subcontinent following the end of the urban Indus Valley Civilization when Indo-European Aryans moved into the vacuum to bring Indo-European patriarchy and empire-building to India. The Aryans became the Brahmans at the top of the caste system that arose.

1500 BCE — 1523 CE (3022 years, 3400-427 BA): Mixtec Empire, a pre-hispanic archaeological culture, corresponding to the ancestors of the Mixtec people; they called themselves ñuu Savi, which means “people or nation of the rain”. It had its first manifestations in the Mesoamerican Middle Preclassic period (12th century BC — 10th century BC) and ended with the Spanish conquest in the first decades of the 16th century. When the Spaniards arrived in La Mixteca, many lords voluntarily submitted as vassals of Spain and retained some privileges. Other lordships tried to resist but were militarily defeated.

1500–400 BCE (1,100 years, 3400-2350 BA): Olmecs were the first major civilization in Mexico. They lived in the tropical lowlands of south-central Mexico, in the present-day states of Veracruz and Tabasco.

1200-300 BCE (900 years, 3150-2250 BA): Late Bronze Age collapse, a broad area wide collapse. Survivors of failed complex societies migrate (some becoming the People of the Sea and Land People) to exploit resources elsewhere which includes other complex societies. During collapse, conflict merely serves to see who inherits the rubble. History does not record the details, but a passage from Herodotus portrays the wandering and migration of Lydians from Anatolia because of famine: 'In the days of Atys, the [legendary] son of Manes, there was great scarcity through the whole land of Lydia ... So the king determined to divide the nation in half ... the one to stay, the other to leave the land. ... the emigrants should have his son Tyrrhenus for their leader ... they went down to Smyrna, and built themselves ships ... after sailing past many countries they came to Umbria ... and called themselves ... Tyrrhenians'. Migrants, aka Land Peoples, increased the human footprint elsewhere leading to collapse and more migrants. The increase in the number of migrants in the 21st century is exponential.

Video mentions the Hekla 3 Icelandic volcano eruption as possible cause, and 1100 BC as a date, which is too late to be a cause. Best guess current date is 1021 BC ±130, but some Egyptologists are certain 1159 BC is the exact date. Embrace ignorance and believe no one. Data says that for centuries steady and reliable rainfall had irrigated vast areas, increasing all human populations... until it didn't, carrying capacity for humans fell, and the human populations were in overshoot.

Another story is that Dorian pressure on the Mycenaean overcomplex society (one Indo-European conqueror invading another) as environmental productivity ebbed (perhaps beginning within the Dorian region in northern Greece) lead to regional collapses in northern Greece and populations of iron slashing sword armed migrant refugees (there was a late Bronze Age bronze shortage) who did what they had to do to persist short term. As already stress neighboring communities were taken, those who couldn't beat 'em joined 'em to move on to other settlements where some adaptive survivors joined them. Within a century Mycenae had collapsed (followed by Minoans...) and the Sea and Land Peoples spread to seriously threaten even Egypt. Assyrians persisted only by withdrawing away from the Mediterranean region back to their stronghold. The Phoenicians were already a sea people and expanded their empire while avoiding the newcomers who, as a dissipative structure, came to pass away with few remnant populations (e.g. Philistines) forming a non-marauding culture of would-be conquerors.

A 2020 video presentation by Eric Cline, archaeologist, offers a systems view of the Late Bronze Age collapse, i.e. 'it's complicated'. Systems collapse of complex interconnected societies has no one cause even if there is one trigger. In hindsight, collapse looks more like a perfect storm of negative feedback loops. This happening may be history's best preview of what is a happening now.

1200–675 BCE (525 years, 3150-2625 BA): Phrygian Kingdom, a kingdom in the west-central part of Anatolia, in what is now Asian Turkey, centered on the Sangarios River. After its conquest, it became a region of the great empires of the time. According to Homer’s Iliad, the Phrygians participated in the Trojan War as close allies of the Trojans. Phrygian power reached its peak in the late 8th century BC under another historical king, Midas, who dominated most of western and central Anatolia and rivaled Assyria and Urartu for power in eastern Anatolia. Over time Phrygians became Christian and Greek-speaking, assimilating into the Byzantine state; after the Turkish conquest of Byzantine Anatolia in the late Middle Ages, the name “Phrygia” passed out of usage as a territorial designation.

1200–546 BCE (654 years, 3150-2496 BA): Kingdom of Lydia, covered all of western Anatolia. Coins appear to have been invented in Lydia around the 7th century BCE and was the first to establish retail shops in permanent locations (first money and malls, what's not to like? They were also the first to debase their coinage.). A considerable building program during the 6th century BCE weakened the wealth of the kingdom. In 547 BC, the Lydians, seeking to enrich themselves as usual, besieged and captured the Persian city of Pteria and enslaved its inhabitants. The Persian king Cyrus The Great's army marched against the Lydians whose empire became a province of the Persian Empire per empire-building as usual.

1180-700 BCE (480 years, 3130-2650 BA): Phrygia. The Phrygians participated in the Trojan War as close allies of the Trojans. Phrygian power reached its peak in the late 8th century BCE when they dominated most of western and central Anatolia and rivaled Assyria and Urartu for power in eastern Anatolia. They gradually weakened and became assimilated into other cultures.

1046–256 BCE (790 years, 2996-2206 BA): The Zhou Empire replaced the Shang Empire. Both surpassed in territory their contemporary Near Eastern empires. The Zhou Empire dissolved in 770 BCE into a feudal multi-state system which lasted for five and a half centuries until the universal conquest of Qin in 221 BCE.

Agro-empowered Sino empire building expansionists were preceded by Man the Hunter expansionists.

1,020 - 722 BCE (298 years, 2970-2672 BA): Kingdom of Israel and Judah. The Kingdom of Israel existed as an independent state until 722 BCE when it was conquered by the Assyrian Empire, while the Kingdom of Judah (or Southern Kingdom) existed as an independent state until 586 BCE when it was conquered by the Neo-Babylonian Empire.

916–612 BCE (304 years, 2866-2562 BA): Neo-Assyrian Empire, the first empire comparable to Rome in organization.

900–200 BCE (700 years, 2850-2150 BA): The Chavín culture is an extinct prehistoric civilization that developed in the northern Andean highlands of Peru. The end was preceded by a large increase in population.

900–100 BCE (800 years, 2850-2050 BA): Etruscan Civilization. The decline was gradual, but by 500 BCE the political destiny of Italy had passed out of Etruscan hands. The last Etruscan cities were formally absorbed by Rome around 100 BCE.

900s–192 BCE (700 years, 2850-2150 BA): Spartan Empire, a prominent city-state in Laconia in ancient Greece. In antiquity, the city-state was known as Lacedaemon, while the name Sparta referred to its main settlement on the banks of the Eurotas River in the Eurotas valley of Laconia, in south-eastern Peloponnese. Around 650 BC, it rose to become the dominant military land-power in ancient Greece. Given its military pre-eminence, Sparta was recognized as the leading force of the unified Greek military during the Greco-Persian Wars, in rivalry with the rising naval power of Athens. Sparta was the principal enemy of Athens during the Peloponnesian War (431–404 BC), from which it emerged victorious after the Battle of Aegospotami. The decisive Battle of Leuctra against Thebes in 371 BC ended the Spartan hegemony, although the city-state maintained its political independence until its forced integration into the Achaean League in 192 BC. The city nevertheless recovered much autonomy after the Roman conquest of Greece in 146 BC and prospered during the Roman Empire, as its antiquarian customs attracted many Roman tourists. However, Sparta was sacked in 396 AD by the Visigothic king Alaric, and underwent a long period of decline, especially in the Middle Ages, when many of its citizens moved to Mystras.

860-590 BCE (248 years, 2810-2540 BA): Kingdom of Urartu. The kingdom rose to power in the mid-9th century BC, but went into gradual decline and was eventually conquered by the Iranian Medes in the early 6th century BCE. The geopolitical region would re-emerge as Armenia shortly after.

814–146 BCE (668 years, 2764-2096 BA): In the western Mediterranean the Empire of Carthage arises and falls. An ancient Semitic civilisation based in North Africa. Initially a settlement in present-day Tunisia, it later became a city-state and then an empire. Founded by the Phoenicians in the ninth century BC, Carthage reached its height in the fourth century BC as one of the largest metropolises in the world. It was the centre of the Carthaginian Empire, a major power led by the Punic people who dominated the ancient western and central Mediterranean Sea. Following the Punic Wars, Carthage was destroyed by the Romans in 146 BC.

808–146 BCE (662 years, 2758-2096 BA): Macedonian Empire or Macedon was an ancient kingdom on the northern periphery of Classical Greece and later the dominant state of Hellenistic Greece. The 7th century legendary foundation to 5th century. Before the 4th century BCE, Macedonia was a small kingdom outside of the area dominated by the great city-states of Athens, Sparta and Thebes. King Philip II (359–336 BC) subdued mainland Greece, and son Alexander, conquered the rest of the known to him world. For a brief period, his Macedonian Empire was the most powerful in the world - the definitive Hellenistic state, inaugurating the transition to a new period of Ancient Greek civilization. After Alexander's death in 323 BC, the ensuing wars led to the partitioning of Alexander's short-lived empire and ended ended with the establishment of the Roman province of Macedonia.

800-100 BCE (700 years, 2750-2050 BA): The Paracas culture was an Andean society with an extensive knowledge of irrigation and water management and significant contributions in the textile arts.

800-250 BCE (550 years, 2750-2200 BA): Scythian Empire, an ancient Eastern Iranic equestrian nomadic people who had migrated during the 9th to 8th centuries BCE from Central Asia to the Pontic Steppe in modern-day Ukraine and Southern Russia, where they remained established from the 7th century BCE until the 3rd century BCE. After being expelled from West Asia by the Medes, the Scythians retreated back into the Pontic Steppe and were gradually conquered by the Sarmatians.

785 BCE–350 CE (1,135 years, 2735-1600 BA): Kingdom of Kush, an ancient kingdom in Nubia, centered along the Nile Valley in what is now northern Sudan and southern Egypt. The region of Nubia was an early cradle of civilization, producing several complex societies that engaged in trade and industry. The Egyptians were the first to identify Kerma as “Kush” and over the next several centuries the two civilizations engaged in intermittent warfare, trade, and cultural exchange. The Kushite king Kashta (c. 750 BCE) was the first to establish himself on the Egyptian throne. He was followed by other great Kushite kings who reigned until the Assyrian invasion of Egypt by Ashurbanipal in 666 BCE. The Kingdom of Kush continued on with Meroe as its capital until an invasion by the Aksumites c. 330 CE which destroyed the city and toppled the kingdom. Overuse of the land, however, had already depleted the resources of Kush and the cities would most likely have been abandoned even without the Aksumite invasion.

753-27 BCE (726 years, 2703-1977 BA): Ancient Rome or Roman Kingdom was founded by Romulus, first of the seven Roman kings. 509 BCE Rome becomes a Republic, ruled by senators following a constitution and laws. 218E BCE Hannibal invades. Carthage was decisively defeated in 202 BCE. Rome defeated Macedonia in 200 BCE and the Seleucids in 190/189 BCE. In 45 BCE Julius Caesar becomes the first dictator of Rome. In 30 BCE, Rome annexed Ptolemaic Egypt. Caesar's assassination ends of the Roman Republic which reorganizes into the Roman empire in 27 BCE to continue expansion.

728–549 BCE (179 years, 2678-2499 BA): Median Empire. The Median Empire was the first empire within the territory of Persia, a political entity centered in Ecbatana [Iran] that existed from the 7th century BCE until the mid-6th century BCE and is believed to have dominated a significant portion of the Iranian plateau, preceding the powerful Achaemenid Empire. The frequent interference of the Assyrians in the Zagros region led to the process of unifying the Median tribes. By 612 BCE, the Medes became strong enough to overthrow the declining Assyrian Empire in alliance with the Babylonians. However, contemporary scholarship tends to be skeptical about the existence of a united Median “kingdom” or “state”, at least for most of the 7th century BCE.

700 BCE – 415 CE (1,115 years, 2650-1535 BA): Ancient Greece was a civilization that flourished from Central Asia to the western end of the Mediterranean Sea. Included in ancient Greece is the period of Classical Greece, which flourished during the 5th to 4th centuries BCE. Classical Greece began with the repelling of a Persian invasion by Athenian leadership. Because of conquests by Alexander the Great of Macedonia, Hellenistic civilization flourished from Central Asia to the western end of the Mediterranean Sea. Classical Greek culture, especially philosophy, had a powerful influence on the Roman Empire, which carried a version of it to many parts of the Mediterranean Basin and Europe. For this reason Classical Greece is generally considered to be the seminal culture which provided the foundation of modern Western non-Christian culture and is considered as the cradle of Western civilization. Vestiges lingered, but the end of Classical Greek culture can be marked by the burning of the Library of Alexandria or death by mob of Hypatia in 415 CE.

700 BCE – 700 CE (1,400 years, 2650-1250 BA): The Zapotec civilization was an indigenous pre-Columbian civilization that flourished in the Valley of Oaxaca in Mexico. The Zapotec left archaeological evidence at the ancient city of Monte Albán in the form of buildings, ball courts, magnificent tombs and grave goods including finely worked gold jewelry. Monte Albán was one of the first major cities in Mesoamerica and the center of a Zapotec state.

678–549 BCE (129 years, 2628-2499 BA): The Medes or Medean Empire, after having allied with the Babylonians to defeat the Neo-Assyrian Empire, the Medes were able to establish their own empire, which was the largest of its day.

626-539 BCE (87 years, 2576-2489 BA): Neo-Babylonian Empire (also Chaldean Empire). The period witnessed a general improvement in economic life and agricultural production, and a great flourishing of architectural projects, the arts and science. The Neo-Babylonian period ended when Cyrus the Great conquered the empire.

612 BCE-72 CE (540 years, 2562-1878 BA): Orontid Dynasty, a hereditary Armenian Dynasty and the rulers of the successor state to the Iron Age kingdom of Urartu. The Orontids established their supremacy over Armenia around the time of the Scythian and Median invasion in the 6th century BCE. It ends in 72 AD when it becomes part of the Roman Empire.

600 BCE to 200 CE (800 years, 2550-1750 BA): Scythia. Steppes of Central Asia to Southern Russia. They formed a loose kingdom called Scythia around 600 BC. Their kingdom lasted until 200 AD when they were defeated by the Sarmatians.

600– 345 BCE (265 years, 2550-2295 BA): Mahajanapadas, India. A set of sixteen kingdoms or oligarchic republics that began when the tribes of the late Vedic period decided to form their own territorial communities, which eventually gave rise to new and permanent areas of settlements as states. It saw the emergence of India's first large cities after the collapse of the Indus Valley Civilization.

600–150 BCE (450 years, 2550-2050 BA): Dong Hu tribal confederation, a tribal confederation of “Hu” nomadic people that was first recorded from the 7th century BCE and was conquered by the Xiongnu in 150 BCE.

550 BCE-1550 CE (2100 years, 2500-400 BA): Sao culture, a civilization that lived in Central Africa from the 6th century BCE to the 16th century AD. They occupied the Lake Chad basin and the Adamawa Plateau in Cameroon, and lived by the Chari River basin in territory that is now part of Cameroon and Chad. The Sao were Sudanic-speaking people who were made up of several patrilineal clans united into a single polity with one language, race, and religion. The city-states of the Sao reached their apex sometime between the ninth and fifteenth centuries CE, and cease to exist after the expansion of the Bornu Empire.

550–330 BCE (220 years, 2500-2280 BA): The Achaemenid Empire, also known as the first Persian Empire, covered Mesopotamia, Egypt, parts of Greece, Thrace, the Middle East, much of Central Asia, and Pakistan. It is considered the first great empire of Ancient History. It was overthrown and replaced by the short-lived empire of Alexander the Great. His Empire was succeeded by three Empires ruled by the Diadochi—the Seleucid, Ptolemaic, and Macedonian, which, despite being independent, are called the "Hellenistic Empire" by virtue of their similarities in culture and administration.

544 BCE-1162 CE (1,706 years, 2496-788 BA): Magadha Empire in eastern India. Following the invasion of India by Indo-European Ayarians after the collapse of the Indus Valley Harappan civilization, empire-building became the norm. Gautama Buddha lived much of his life in the kingdom of Magadha. The Magadha region hosted many nominal and actual empires. Some were empires in name but some were merely regime changes, so each and every empire will not be listed separately.

544–492 BCE (52 years): Haryanka Empire (Bimbisara Dynasty)
492–413 BCE (79 years): Udayin Empire (Udayin Dynasty)
413-344 BCE (79 years): Shishunaga Empire
344-321 BCE (23 years): Nanda Empire
321-185 BCE (136 years): Maurya Empire
185-75 BCE (110 years): Shunga Empire
75-30 BCE (45 years): Kanva Empire
30 BCE-320 CE (350 years): Satavahana Empire
321-550 CE (229 years): Gupta Empire
750-1162 CE (412 years): Pala Empire

500-BCE to 600 CE (1100 years, 2450-1150 BA): West Amazonia ‘Garden Urbanism’ culture, Sangay, Kilamope and Upano cultures, discovered by LiDAR, 6,000 earthworks in what is now eastern Ecuador. Corn based, three crops/year dispersed agrarian urban populations in 15 urban centers, houses and communal buildings, set amid vast tracts of carefully drained farmland and linked by a network of roads. A dispersed and extensive form of city compared to those in Eurasia. Decline from 300 - 600 BCE, no occupation for 200-600 years. After 200 years of environmental recovery, the Huapula culture began to move into the area to reuse remaining infrastructure, i.e. the Kilamope and Upano cultures collapsed to regional extinction.

453-221 BCE (232 years, 2403-2171 BA): Warring States Period, Sino region. Different scholars point toward different dates ranging from 481 BC to 403 BC as the "true" beginning of the Warring States period. Scholars are divided into five schools of thought as to the true beginning of the Warring States era, and all are wrong as there was no one event/incident beginning the period. The Warring States era overlaps with the dissolution of the Zhou Dynasty when the king of Zhou ruled merely as a figurehead during descent.

Over 100 smaller states, who had been "united" by conquest under the Zhou Dynasty, contended for dominance and were in due time assimilated/subsumed/consolidated by conquest into seven major states large enough to contend with one another. This was the period of Zhuangzi and the Hundred Schools of Thought, of which all but one sought to serve their state (e.g. Confucius and Mencius).

What once looked like a near consensus narrative to the Western mind (that growth is good—in the 20th century global academics were mostly singing the same song, the one of the globalizing monetary culture of the Modern Techno-industrial socioeconomic-political world system whose bread they ate) is now fragmenting into another ideological battle ground within which another Hundred (to Thousands) of Schools of Thought are and will increasingly contend to see which can deny that they are wrong the longest. Laozi may have lived in the early Warring States period or the dissolution preceding it. This period may resemble the dissolution of the Euro-Sino Empire in the 21st century, but without a global reunification. O Laozi/Zhuangzi, the voices not serving empire, where art thou?

323-31 BCE (292 years, 2273-1986 BA): Hellenist Period, Greece. Starts with the death of Alexander the Great in 323 BC and ends with the conquest by the Roman Empire as signified by the Battle of Actium in 31 BCE and fall of the Ptolemaic Kingdom in 30 BCE. At this time, Greek cultural influence and power was at its peak in Europe, North Africa and Western Asia, experiencing prosperity and progress in the arts, exploration, literature, theatre, architecture, music, mathematics, philosophy, and science (for a time).

321–185 BCE (136 years, 2271-2135 BA): Maurya Empire, in India during the Axial Age appeared a geographically extensive and powerful empire, ruled by the Mauryan Dynasty. The empire rapidly expanded westward across central and western India, taking advantage of the disruptions of local powers following the withdrawal by Alexander the Great. By 320 BC, the Maurya Empire had fully occupied northwestern India as well as defeating and conquering the satraps left by Alexander. Under Emperor Asoka the Great, the Maurya Empire became the first Indian empire to conquer all of the Indian Peninsula—an achievement repeated only twice, by the Gupta and Mughal Empires. In the reign of Asoka Buddhism spread to become the dominant religion in ancient India. It has been estimated that the Maurya Dynasty controlled an unprecedented one-third of the world's entire economy, was home to one-third of the world's population at the time (an estimated 50 million out of 150 million humans), contained the world's largest city of the time (Pataliputra, estimated to be larger than Rome under Emperor Trajan) and according to Megasthenes, the empire wielded a military of 600,000 infantry, 30,000 cavalry, and 9,000 war elephants.

331 BCE to 428 CE (442 years, 2271-1522 BA): Kingdom of Armenia. Originally inhabited by Proto-Armenian tribes which committed empire on the chiefdom level before becoming a unitary state or nation. The highlands were first united by tribes in the vicinity of Lake Van into the Kingdom of Van. The kingdom competed with Assyria over supremacy in the highlands of Ararat and the Fertile Crescent. The Armenian kingdom was the first state to embrace Christianity officially. Ideological belief-based systems compete for minds instead of energy and material resources.

312–63 BCE (249 years, 2269-2013 BA): The Seleucid Empire was a Hellenistic state ruled by the Seleucid Dynasty. It was founded by Seleucus I Nicator following the division of the Macedonian empire vastly expanded by Alexander the Great.

305–30 BC (275 years, 2255-1980 BA): Ptolemaic Kingdom, Egypt. Started with Ptolemy I Soter who declared himself pharaoh of Egypt and created a powerful Macedonian Greek Dynasty after the death of Alexander the Great in 323 BC and which ended with the death of Cleopatra and the Roman conquest in 30 BC.

300s BCE–1279 CE (1,570 years, 2250-671 BA): Chola Dynasty, India, one of the longest-ruling dynasties in history. The Chola fleet represented the zenith of ancient Indian sea power.

281 BCE–62 CE (343 years, 2231-1888 BA): Pontic (Pontus) Empire, kingdom was proclaimed by Mithridates I in 281 BCE and lasted until its conquest by the Roman Republic in 63 CE. The Kingdom of Pontus reached its largest extent under Mithridates VI the Great, who conquered Colchis, Cappadocia, Bithynia, the Greek colonies of the Tauric Chersonesos, and for a brief time the Roman province of Asia. After a long struggle with Rome in the Mithridatic Wars, Pontus was defeated. The western part of it was incorporated into the Roman Republic as the province Bithynia et Pontus; the eastern half survived as a client kingdom until 62 AD.

256–125 BCE (131 years, 2206-2075 BA): Greco-Bactrian Kingdom, north of present-day Afghanistan. Formed when it seceded from the Seleucid Empire. Highly expansionistic in strength, weakened by excess, Bactria was invaded by nomadic tribes from the North and destroyed not unlike Rome was later to be.

247 BCE – 224 CE (445 years, 2197-1726 BA): Parthian Empire, also known as the Arsacid Empire, was a major Iranian political and cultural power in ancient Iran and Iraq.

230 BCE-220 CE (450 years, 2180-1730): Satavahana Empire, an ancient Indian Brahmin dynasty based in the Deccan region. The Satavahanas were early issuers of Indian state coinage struck with images of their rulers. They formed a cultural bridge and played a vital role in trade and the transfer of ideas and culture to and from the Indo-Gangetic Plain to the southern tip of India. The dynasty was extinguished following the rise of its feudatories, perhaps on account of a decline in central power.

221–207 BCE (14 years, 2171-2157 BA): Qin Dynasty in China, the era of the Warring States ended with the universal conquest of Qin. The King of Qin, Ying Zheng, became China's First Emperor and began the pattern of successive dynasties. Ying Zheng connected all the existing defense walls of northern China into what is known today as the Great Wall of China which marked the northern frontier of China. The Qin Dynasty was short lived and in 207 BCE was overthrown by the Han Dynasty.

209-25 BCE (184 years, 2159-1975 BA): Xiongnu Empire, China. A tribal confederation of nomadic peoples who, according to ancient Chinese sources, inhabited the eastern Eurasian Steppe. After their previous overlords migrated into Central Asia during the 2nd century BC, the Xiongnu became a dominant power on the steppes of north-east Central Asia later called Mongolia.

207 BCE – 220 CE (457 years, 2157-1730 BA): Han Dynasty became one of East Asia's most long-lived dynasties. In the Second century CE the Han Empire expanded into Central Asia. By this time only three Empires stretched between the Pacific and the Atlantic—China, Parthia, and Rome. The Roman Empire came later, but existed during the Han Empire, lasting not quite as long.

202-40 BCE (162 years, 2152-1990 BA): Numidia, North Africa. It is considered to be one of the first major states in the history of Algeria and the Berber world. After the death of the last king, Numidia became the Roman province.

200 BCE to 200 CE (400 years, 2150-1700 BA): Chera Dynasty, India. The Chera people of southern India owed their importance to exchange of spices, especially black pepper, with Middle Eastern and Graeco-Roman merchants.

185–75 BCE (110 years, 2135-2025 BA): Shunga Empire, eastern India, noted for its numerous wars with both foreign and indigenous powers. The dynasty rapidly discorporated after the death of its second king.

100 BCE – 800 CE (900 years, 2050-1100 BA): The Nazca culture (also Nasca) was the archaeological culture that flourished from beside the arid, southern coast of Peru in the river valleys of the Rio Grande de Nazca drainage and the Ica Valley. The Nazca produced an array of crafts and technologies such as ceramics, textiles, and geoglyphs—specifically the Nazca Lines. They also built an impressive system of underground aqueducts, known as puquios, that still function today. From 500 CE, the civilization started to decline and by 750 CE the civilization had fallen completely. This is thought to have occurred when an El Niño triggered widespread and destructive flooding. Evidence also suggests that the Nazca people may have exacerbated the effects of these floods by gradually cutting down trees to make room for maize and cotton agriculture. These trees play an extremely important role as the ecological keystone of this landscape: in particular preventing river and wind erosion. Gradual removal of trees would have exposed the landscape to the effects of climate perturbations such as El Niño, leading to erosion and failure of irrigation systems.

100 BCE-550 CE (650 years, 2050-1400 BA): Teotihuacan, central Mexico. Teotihuacan was the largest city in the pre-Columbian Americas, with a population estimated at 125,000 or more, making it the sixth largest city in the world during its epoch. Its major monuments were sacked and systematically burned around 550 CE.

100 BCE – 900 CE: (1000 years, 2050-1050 BA): The Quimbaya civilization was a South American civilization in Columbia, noted for spectacular gold work characterized by technical accuracy and detailed designs. The Quimbaya reached their zenith during the 4th to 7th century CE period. Around the 10th century the Quimbaya culture disappeared entirely due to unknown circumstances.

100 BCE-c. 200 CE (300 years, 2050-1750 BA): Satavahana Dynasty, India. They conquered predecessors and the kingdom fragmented into smaller states by the early 3rd century CE.

75-30 BCE (45 years, 2025-1980 BA): Kanva Empire, eastern India. The last ruler of the Shunga Dynasty was overthrown by his minister who founded the Kanva Dynasty in 75 BC, so more of a regime change than a new empire as was the Satavahana Empire that followed.

57 BCE-668 CE (725 years, 2007-1282 BA): Three Kingdoms of Korea, The three kingdoms occupied the entire Korean Peninsula and most of Manchuria. Frequent warfare, here as elsewhere, played a major role in the development of peninsular states.

57 BCE — 935 CE (992 years, 2007-1015 BA): Silla, Kingdom of, 57 BCE — 935 CE, a Korean kingdom located on the southern and central parts of the Korean Peninsula. Silla, along with Baekje and Goguryeo, formed the Three Kingdoms of Korea. Silla had the lowest population of approximately 850,000 people (170,000 households), which was significantly smaller than those of Baekje (3,800,000 people) and Goguryeo (3,500,000 people). After nearly 1,000 years of rule, Silla fragmented into the brief Later Three Kingdoms of Silla, Later Baekje, and Taebong, handing over power to Goryeo in 935.

37 BCE - 668 CE (705 years, 1987-1282 BA): Goguryeo Kingdom, a Korean kingdom, one of the three, located in the northern and central parts of the Korean Peninsula and the southern and central parts of modern day Northeast China. At its peak of power, Goguryeo controlled most of the Korean Peninsula, large parts of Manchuria and parts of eastern Mongolia and Inner Mongolia as well as Russia. It was an active participant in the power struggle for control of the Korean peninsula and was also associated with the foreign affairs of neighboring polities in China and Japan. Internal strife (531 to 551) lead to wars and decline, and a Chinese army invaded, ending the Kingdom in 668.

27 BCE – 395 CE (422 years, 1977-1555 BA): The Imperial Roman Empire was the first nation to invent and embody the concept of empire in their two mandates: to wage war and to make and execute laws. They were the most extensive Western empire until the early modern period, and left a lasting impact on Western Europe. The empire split in 395 CE and the Western Roman Empire fell in 476 CE. Many languages, cultural values, religious institutions, political divisions, urban centers, and legal systems can trace their origins to the Roman Empire. The Roman Empire governed and rested on exploitative actions, but for two hundred years they didn't have to conquer anyone (Pax Romana). They took slaves and money from the peripheries to support the imperial center. However, the absolute reliance on conquered peoples to carry out the empire's fortune, sustain wealth, and fight wars would ultimately lead to the collapse of the Roman Empire. The Romans were strong believers in what they called their "civilizing mission". This term was legitimized and justified by writers like Cicero who wrote that only under Roman rule could the world flourish and prosper. This ideology, that was envisioned to bring a new world order, was eventually spread across the Mediterranean world and beyond. People started to build houses like Romans, eat the same food, wear the same clothes and engage in the same cruel games. Even rights of citizenship and authority to rule were granted to people not of Roman or Italian birth. This authority given to people outside of Roman culture is an example of how its empire collapsed, with a strong dependence on "foreign" rulers.

18 BCE–660 CE (678 years, 1968-1290 BA): Baekje (Paekche) Kingdom, a Korean kingdom, one of the Three Kindoms, located in southwestern Korea. It was one of the Three Kingdoms of Korea, together with Goguryeo and Silla. While the three kingdoms were in separate existence, Baekje had the highest population of approximately 3,800,000 people (760,000 households), which was similar to that of Goguryeo (3,500,000 people) and much larger than that of Silla (850,000 people).

19–226 CE (208 years, 1932-1724 BA): Indo-Parthian Kingdom, ruled an area covering parts of eastern Iran, various parts of Afghanistan and the northwest regions of the Indian subcontinent (most of modern Pakistan and parts of northwestern India). The rulers may have been members of the House of Suren, and the kingdom has even been called the “Suren Kingdom” by some authors. The governor declared independence from the Parthian Empire, leading expeditions to the east, conquering territory from the Indo-Scythians and Indo-Greeks, thus transforming the kingdom into an empire. Conquest by the Sasanian Empire.

30–375 CE (205 years, 1920-1575 BA): Kushan Empire, spread to encompass much of Afghanistan and then the northern parts of the Indian subcontinent. The Kushan Dynasty had diplomatic contacts with the Roman Empire, Sasanian Persia, the Aksumite Empire and the Han Dynasty of China. While much philosophy, art, and science was created within its borders, the only textual record of the empire's history today comes from inscriptions and accounts in other languages, particularly Chinese.

35–415 CE (380 years, 1915-1535 BA): Western Satrap (Western Kshatrapa) Kingdom, were Indo-Scythian (Saka) rulers of the western and central parts of India (extending from Saurashtra in the south and Malwa in the east, covering modern-day Sindh, Gujarat, Maharashtra, Rajasthan and Madhya Pradesh states), between 35 and 415 CE. Called “Western Satraps” in modern historiography in order to differentiate them from the “Northern Satraps”, who ruled in Punjab and Mathura until the 2nd century CE. The Western Satraps, having been defeated by the Abhiras/Ahirs, declined rapidly during the second half of the third century.

50–1650 CE (1,160 years, 1900-300 BA): Tairona civilization was a group of chiefdoms in the region of Sierra Nevada de Santa Marta, Colombia, South America, which goes back at least to the 1st century CE and had significant demographic growth around the 11th century. In the post population peak recovery, the Tairona 3 phase, the Tairona lived sustainably until all Taironans, except the highland Kogi, were eliminated by determined Spanish efforts at genocide (1600–1650 CE). A remnant population, the Kogi, retain an intact culture and complex society, the only one to have resisted assimilation into the industrial society collective.

68–550 CE (482 years, 1832-1400 BA): Funan, Kingdom of, an ancient Indianized state — or, rather a loose network of states (Mandala) — located in mainland Southeast Asia centered on the Mekong Delta. Extensive human settlement in the region may go back as far as the 4th century BCE. Funan may have been a collection of city-states that sometimes warred with one another and at other times constituted a political unity. The Funanese established a strong system of mercantilism and commercial monopolies that would become a pattern for empires in the region. Funan was superseded and absorbed in the 6th century by the Khmer polity.

100–800 CE (700 years, 1850-1150 BA): The Moche or Mochica culture, Early Chimu flourished in northern Peru with its capital near present-day Moche and Trujillo. They were likely a group of autonomous polities that shared a common elite culture, as seen in the rich iconography and monumental architecture that survived. Moche history may be broadly divided into three periods – the emergence of the Moche culture in Early Moche (100–300 CE), its expansion and florescence during Middle Moche (300–600 CE), and the urban nucleation and subsequent collapse in Late Moche (500–750 CE). The defensive works suggest social unrest, possibly the result of climatic changes, as factions fought for control over increasingly scarce resources.

100 – c. 940 CE (840 years, 1850-1010 BA) Aksumite Empire, Kingdom of Aksum also known as the Kingdom of Axum, northern Ethiopia. Emperors were powerful sovereigns, styling themselves as King of kings, and became a major player on the commercial trade route between the Roman Empire and Ancient India.

100–650 CE (550 years, 1850-1300 BA): The Lima culture was an indigenous civilization which existed in modern-day Lima, Peru. This pre-Incan culture, which overlaps with surrounding Paracas, Moche, and Nazca civilizations, was located in the desert coastal strip of Peru. Starting around 600, climatic and environmental changes in the Andean region were brought about by cycles of droughts and El Niño phenomenon. The Lima underwent radical reorganizations and shifting populations in order to compensate for the change in rainfall and water availability. Lima culture was steadily disbanded, and new culture groups developed and dominated Coastal Peru.

150 BCE–400 CE (250 years, 1800-820 BA): Indo-Scythian (Saka) Kingdom, a group of nomadic Iranian peoples of Scythian origin who migrated from Central Asia southward into the northwestern Indian subcontinent, precisely into the modern-day South Asian regions of Afghanistan, Pakistan and northern India. The migrations persisted from the middle of the 2nd century BCE to the 4th century CE. The Indo-Scythians extended their supremacy over north-western subcontinent, conquering the Indo-Greeks and other local kingdoms. The Indo-Scythians were apparently subjugated by the Kushan Empire.

200–1130 CE (930 years, 1750-820 BA): Mimbres culture, Southwest USA culture known only by pottery style/ruins. Pottery production ended 1130 CE suggesting collapse of complex society. Some farming persisted in a declining population to 1450 CE when all agriculture in the region ended.

220–1911 CE (1691 years, 1730-39 BA): Imperial China: May be considered to include Han dynasty that ended in 220. Han dark age, 220–c.580; Sui, Tang, and Five dynasties periods, c.581–960; Song dynasty period, 960–1279; Yuan dynasty period, 1279–1368; Ming dynasty period, 1368–1644; Qing or Manchu dynasty period, 1636–1911.

224–651 CE (427 years, 1726-1299 BA): Sasanian Empire, also called the "Empire of Empires," was the last Iranian empire before the rise of Islam.

250–900 CE (650 years, 1700-1050 BA): Mayan Classic period is largely defined as the period during which the lowland Maya raised dated monuments using the Long Count calendar. This period marked the peak of large-scale construction and urbanism, the recording of monumental inscriptions, and demonstrated significant intellectual and artistic development, particularly in the southern lowland regions. The Classic period Maya political landscape has been likened to that of Renaissance Italy or Classical Greece, with multiple city-states engaged in a complex network of alliances and enmities.

300 and 1500 CE (1200 years, 1650-450 BA): The Hohokam was a culture in the North American Southwest in what is now part of Arizona, United States, and Sonora, Mexico. Extensive canals supported agriculture and a large population, for a time, and was the most complex in the pre-contact north of Mesoamerica. It had collapsed prior to Spanish conquest, but after the Pueblo collapse, some of whom emigrated to Hohokam territory and persisted for a time before being assemilated into Hohokam culture or otherwise failing to persist.

319–c. 550 CE (231 years, 1669-1400 BA): Gupta Empire, an ancient Indian empire. At its zenith, from approximately 319 to 467 CE, it covered much of the Indian subcontinent. This period has been considered as the Golden Age of India by some historians, although this characterisation has been disputed by other historians. The ruling dynasty of the empire was founded by Gupta. The 5th-century CE Sanskrit poet Kalidasa credits the Guptas with having conquered about twenty-one kingdoms, both in and outside India. Decline and Hun invasion, disestablished 550.

320–550 CE (230 years, 1630-1400 BA): The Gupta Empire was an ancient Indian empire, founded by Sri Gupta, and covered much of the Indian subcontinent.

330–555 CE (225 years, 1620-1395 BA): Rouran (Juan Juan) Khaganate, a tribal confederation and later state founded by a people of Proto-Mongolic Donghu origin. The Rouran supreme rulers used the title of “khagan”, a popular title borrowed from the Xianbei. The Rouran Khaganate lasted from the late 4th century until the middle 6th century, when they were defeated by a Göktürk rebellion at the peak of their power, which subsequently led to the rise of the Turks in world history.

330–1453 CE (1,123 years, 1620-497 BA): Byzantine Empire, Eastern Roman remnant of empire persisted by intentionally reducing complexity, scaling back to avoid, for a time, collapse. The weakening, slowly declining Byzantine Empire, fell to the expanding Islamic Caliphate. Some scholars and their books were able to emigrate to Europe to join the rebirth of learning that served expanding empires.

370–469 CE (99 years, 1580-1481 BA): Huns, pastoral nomadic people who lived in Central Asia, the Caucasus, and Eastern Europe. The Huns established a vast, if short-lived, dominion in Europe, conquering the Goths and many other Germanic peoples living outside of Roman borders, and causing many others to flee into Roman territory. The Huns, especially under their King Attila, made frequent and devastating raids into the Eastern Roman Empire. In 451, the Huns invaded the Western Roman province of Gaul, where they fought a combined army of Romans and Visigoths, and in 452 they invaded Italy. After Attila's death in 453, the Huns ceased to be a major threat to Rome and lost much of their empire.

418–c. 720 CE (302 years-, 1532-1230 BA): Visigothic Kingdom, occupied what is now southwestern France and the Iberian Peninsula. The Visigoths were romanized central Europeans who had moved west from the Danube Valley. When Western Roman Empire fell in 476 AD, the Visigoths believed they had the right to take the territories that Rome had promised in Hispania in exchange for attempting to restore the Roman order. By 716, most of the Iberian Peninsula was under Islamic rule.

435–534 CE (99 years-, 1515-1416 BA): Vandals, Kingdom of the, a confederation of Vandals and Alans, which is one of the barbarian kingdoms established under Gaiseric, a Vandal warrior. It ruled in North Africa and the Mediterranean from 435 to 534 AD. In 429 AD, the Vandals, estimated to number 80,000 people, had crossed by boat from Hispania to North Africa. They advanced eastward, conquering the coastal regions of what is now Tunisia, and Algeria. In 435, the Western Roman Empire, then ruling North Africa, allowed the Vandals to settle in the provinces of Numidia and Mauretania when it became clear that the Vandal army could not be defeated by Roman military forces. In 439 the Vandals renewed their advance eastward and captured Carthage, the most important city of North Africa. The fledgling kingdom then conquered the Roman-ruled islands of Mallorca, Sicily, Sardinia, and Corsica in the western Mediterranean. In the 460s, the Romans launched two unsuccessful military expeditions by sea in an attempt to overthrow the Vandals and reclaim North Africa. The conquest of North Africa by the Vandals was a blow to the beleaguered Western Roman Empire as North Africa was a major source of revenue and a supplier of grain (mostly wheat) to the city of Rome. The Vandal Kingdom ended in 534, when it was conquered by Belisarius in the Vandalic War and incorporated into the Eastern Roman Empire (or Byzantine Empire). The surviving Vandals either assimilated into the indigenous African population or were dispersed among the Byzantine territories.

440s–560 CE (120 years, 1510-1390 BA): Hephthalites or Whte Huns, were a people of Central Asia who were militarily important circa 450–560. They were based in Bactria and expanded east to the Tarim Basin, west to Sogdia and south through Afghanistan to northern India. They were a tribal confederation and included both nomadic and settled urban communities. They have often been linked to the Huns who invaded Eastern Europe during the same period, and/or have been referred to as "Huns", but there is no consensus among scholars about such a connection. The Imperial Hephthalites were militarily important from 450 CE when they defeated the Kidarites, to 560 CE, when combined forces from the First Turkic Khaganate and the Sasanian Empire defeated them.

476 CE (to present, 1474 BA to present): Euro-Sino Empire, Euro beginnings after fall of Western Roman Empire as empire of belief before becoming a multiplicity of about 300 feudal societies/principalities by 1495, some becoming maritime powers, who transitioned from wood to fossil fuels to become the first industrial global empire which climaxed in the Sino region. Did 'you' begin as a fertilized ovum, a newborn, or as an adult? An alternative beginning date, 0 BA/AA, is 1950 CE as that is when the global growth economy dramatically accelerated and when all prior empires, apart from a few outliers such as North Korea, had been fully assimilated, resistance as nation-states having proved futile.

500–1000 CE (500 years, 1450-950 BA): The Wari flourished in the south-central Andes and coastal area of modern-day Peru. The Wari culture began to deteriorate around 800 CE. Archaeologists have determined that the city of Wari was dramatically depopulated by 1000 CE. Archaeological evidence shows significant levels of interpersonal violence, suggesting that warfare and raiding increased amongst rival groups upon the collapse of the Wari state structure.

500–1400 CE (900 years, 1450-550 BA): The Casarabe culture built a low-density urban system that included straight, raised causeways running for several kilometers (sustainability enthusiasts who dream of all humanity living in ecovillages to become like the Casarabe cite a 1542 Spanish confabulous report of '30 legues', or 165 km, of 'very fine highways' connecting 'very large cities that glistened in white', but note the dates of the rise and fall of the Casarabe empire), canals and reservoirs. Such low-density urban sprawl from pre-Columbian times was previously unknown in the Amazon or anywhere else in South America. They were maize farmers and hunter/fisher foragers. The lidar data has revealed 26 sites. Beginning about 1250 CE other complex low-density development arose along the Southern Rim Area of the Amazon. The pattern was repeated. The Casarabe endgame may have resulted in a wave of migrants spreading out (auto-organizing a marauding horde culture). Outliers fortified their settlements, but by 1500 CE all complex societies in the Southern Rim Region experienced a Darker Age without recovery (confabulists note that as regional collapse ended about 1500, 8 years after Columbus sailed to the Caribbean, that Old World diseases caused the collapse and caused the dying people to build extensive fortifications in the 15th century after abandonment of the Casarabe region by 1400). As migrants spread, as the Land (and Sea) Peoples of the Late Bronze Age Collapse did, settlements fall and some survivors join the marauding horde culture, increasing their numbers, who move on to repeat the pattern over multiple generations until they can't. The indigenous did not live in large cities sustainably glistening in white and neither will those who imagine posterity will if 8 billion people (or 10.4 billion as projected for 2086) would just choose to live in ecovillages like the Casarabe did before the Spanish conquest.

539–1218 CE (679 years, 1411-732 BA):Kyrgyz Khaganate, the khaganate’s territory at its height would briefly include parts of modern-day China, Kazakhstan, Kyrgyzstan, Mongolia, and Russia. After the 10th century, there was little information on the Yenisei Kyrgyz.

567– after 822 CE (255 years, 1383-1128 BA): Avar Khaganate, the Pannonian Avars were an alliance of several groups of Eurasian nomads of various origins. They established the Avar Khaganate, which spanned the Pannonian Basin and considerable areas of Central and Eastern Europe from the late 6th to the early 9th century.

568–774 CE (206 years, 1382-1176 BA): Lombard Kingdom, was an early medieval state established by the Lombards, a Germanic people, on the Italian Peninsula. The king was traditionally elected by the very highest-ranking aristocrats, the dukes, as several attempts to establish a hereditary dynasty failed. The kingdom was subdivided into a varying number of duchies, ruled by semi-autonomous dukes, which were in turn subdivided into gastaldates at the municipal level. The capital of the kingdom and the center of its political life was Pavia in the modern northern Italian region of Lombardy. Over time, the Lombards gradually adopted Roman titles, names, and traditions. Initially the Lombards were Arian Christians or pagans, which put them at odds with the Roman population as well as the Byzantine Empire and the Pope. However, by the end of the 7th century, their conversion to Catholicism was all but complete. Nevertheless, their conflict with the Pope continued and was responsible for their gradual loss of power to the Franks, who conquered the kingdom in 774.

581–657 CE (76 years, 1369-1293 BA): Western Turkic Khaganate or Onoq Khaganate was a Turkic khaganate formed as a result of the wars in the beginning of the 7th century after the split of the Göktürk Khaganate (founded in the 6th century in Mongolia by the Ashina clan) into the Western khaganate and the Eastern Turkic Khaganate.The Western Turkic Khaganate was subjugated by the Tang Empire in 657

600–1300 CE (700 years, 1350-650 BA): Cahokia was the largest and the most influential urban settlement in the Mississippian culture which developed advanced societies across much of what is now the central and southeastern United States, beginning more than 1000 years before European contact. Cahokia's population, peak estimate 40,000, began to decline during the thirteenth century, and then was abandoned post collapse.

600–1600 CE (1,000 years, 1350-350 BA): The Muisca (or Chibcha) civilization flourished in ancient Colombia. The Muisca Confederation 1450–1537 CE (87 years) was a rather loose confederation of different Muisca chiefdoms in the central Andean highlands of present-day Colombia. Population between 300,000 and two million people, one of four advanced civilizations of the Americas (apart from the Aztec, Mayans and Incas. They were developing writing. They were advanced but not war-like, there was no absolute monarch, nor was it an empire-as-usual, because it did not dominate other ethnic groups or peoples. The chiefdoms were united by an empire of belief, a priest class who, unlike monarchs and military rulers, neglected to indulge in vast monument building. The shared military force was for defense, not conquest. Defeated by Spanish conquistadors who encountered them in 1537 and conqued them by 1542.

600–1000 CE (400 years, 1350-950 BA): Tiwanaku (Tiahuanaco) culture, a Pre-Columbian polity in western Bolivia based in the southern Lake Titicaca Basin. Tiwanaku was one of the most significant Andean civilizations. Its influence extended into present-day Peru and Chile. Its capital was the monumental city of Tiwanaku, located at the center of the polity’s core area in the southern Lake Titicaca Basin. This area has clear evidence for large-scale agricultural production on raised fields that probably supported the urban population of the capital. Researchers debate whether these fields were administered by a bureaucratic state (top-down) or through a federation of communities with local autonomy (bottom-up). Tiwanaku was once thought to be an expansive military empire, based mostly on comparisons to the later Inca Empire. However, recent research suggests that labelling Tiwanaku as an empire or even a state may be misleading. Tiwanaku is missing a number of features traditionally used to define archaic states and empires: there is no defensive architecture at any Tiwanaku site or changes in weapon technology, there are no princely burials or other evidence of a ruling dynasty or a formal social hierarchy, no evidence of state-maintained roads or outposts, and no markets. Tiwanaku was a multi-cultural network of powerful lineages that brought people together to build large monuments. Tiwanaku grew into the Andes’ most important pilgrimage destination and one of the continent’s largest Pre-Columbian cities, reaching a maximum population of 10,000 to 20,000 around 800 CE. Around 1000 AD, Tiwanaku ceramics stopped being produced as the state’s largest colony (Moquegua) and the urban core of the capital were abandoned within a few decades. One theory of collapse is that internal social dynamics led to Tiwanaku’s demise. Some areas of the capital show signs of intentional destruction, though this could have taken place at any time. Monolithic gates, like Gateway of the Sun, were tipped over and broken. By the end of Tiwanaku V period the Putuni complex was burned and food storage jars smashed. This indicates an event of destruction, followed by abandonment of the site. Colonies in Moquegua and on Isla del Sol were also abandoned around this time. Dispersing remnant populations in search of new suitable environments might have caused long-distance ripple effects of both migration and technological diffusion across the south-central and south Andes between c. 1100 to 1300 CE.

606 -647 CE (41 years, 1344-1303 BA): Harsha Empire, a one emperor empire who ruled northern India. He was the son of Prabhakaravardhana who had defeated the Alchon Hun invaders. At the height of Harsha’s power, his realm covered much of northern and northwestern India. Harsha was defeated by the Emperor Pulakeshin II when he tried to expand his empire into the southern peninsula of India.

618–907 CE (289 years, 1332-1043 BA): In East Asia, various Celestial Empires arose periodically between periods of war, civil war, and foreign conquests. The greatest of them was the Tang Empire.

618–842/848 CE (230 years, 1332-1102 BA): Tibetan Empire, an empire centered on the Tibetan Plateau, formed as a result of imperial expansion under the Yarlung dynasty heralded by its 33rd king, Songtsen Gampo, in the 7th century. The empire further expanded under the 38th king, Trisong Detsen, and expanded to its greatest extent under the 41st king, Rapalchen, whose 821–823 treaty was concluded between the Tibetan Empire and the Tang dynasty. This treaty, carved into the Jokhang Pillar, delineated Tibet as being in possession of an area larger than the Tibetan Plateau, stretching east to Chang’an, west beyond modern Afghanistan, and south into modern India and the Bay of Bengal. A civil war that arose over who should be a successor led to the collapse of the Tibetan Empire. The period that followed, known traditionally as the Era of Fragmentation, was dominated by rebellions against the remnants of imperial Tibet and the rise of regional warlords.

622–1927 CE (1305 years, 1336-7 BA): In Middle East, the Muslim Empire was a secession of caliphates, dynasties, beginning with Muhammad's expansionist conquests in 622 to his conquest of Mecca in 630 whose empire building ended upon his death in 632. Rashidun Caliphate, the first caliphate to succeed the Islamic prophet Muhammad. It was ruled by the first four successive caliphs of Muhammad after his death in 632 CE (11 AH). During its existence, the empire was the most powerful economic, cultural, and military force in the Middle East. Umayyad Caliphate, the second caliphate established after the death of the Islamic prophet Muhammad. From 661–750. Abbasid Caliphate, the third caliphate to succeed the Islamic prophet Muhammad. It was founded by a dynasty descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib (566–653 CE), from whom the dynasty takes its name. From 750–1258, 1261–1517, in 1258 with the sack of Baghdad by the Mongols under Hulagu Khan and the execution of al-Musta'sim. The Abbasid line of rulers, and Muslim culture in general, re-centred themselves in the Mamluk capital of Cairo in 1261. Ottoman Empire, the fourth major caliphate, the Ottoman Caliphate, the rulers of the Ottoman Empire claimed caliphal authority from 1517 until the caliphate was abolished as part of the 1924 secularisation of Turkey.

632–661 CE (29 years, 1318-1289 BA): The Rashidun Caliphate expanded from the Arabian Peninsula and swiftly conquered the Persian Empire (633–654 CE) and much of the Byzantine Roman Empire.

650-1430 CE (780 years, 1300-520 BA): Gao Empire, 7th century–1430, founded along the Niger River, it was a profitable location for fisherman to settle, and is one of the oldest trading centers in western Africa. It became Islamic early 11th century and was able to flourish most notably via the trans-Saharan trade of gold, copper, slaves, and salt.

650–969 CE (319 years, 1300-981 BA): Khazar Khaganate, a nomadic Turkic people that established a major commercial empire covering the southeastern section of modern European Russia, southern Ukraine, Crimea, and Kazakhstan. They created what for its duration was the most powerful polity to emerge from the break-up of the Western Turkic Khaganate. Astride a major artery of commerce between Eastern Europe and Southwestern Asia, Khazaria became one of the foremost trading empires of the early medieval world, commanding the western marches of the Silk Road and playing a key commercial role as a crossroad between China, the Middle East and Kievan Rus’. For some three centuries (c. 650–965) the Khazars dominated the vast area extending from the Volga-Don steppes to the eastern Crimea and the northern Caucasus. The Prince of Kiev Sviatoslav I finally succeeded in destroying Khazar imperial power in the 960s, in a circular sweep that overwhelmed Khazar fortresses, and then back to Kyiv. Sarkel fell in 965, with the capital city of Atil following, c. 968 or 969.

650–1377 CE (727 years, 1300-573 BA): Srivijaya Empire. In the 7th century, Maritime Southeast Asia witnessed the rise of a Buddhist thalassocracy (sea based empire), the Srivijaya Empire, which thrived for 600 years and was succeeded by the Hindu-Buddhist Majapahit Empire that ruled from the 13th to 15th centuries.

661–750 CE (89 years, 1289-1200 BA): The Umayyad Caliphate expanded across North Africa and into the Iberian Peninsula. By the beginning of the 8th century, the Umayyad Caliphate had become the largest empire in history, it would not be surpassed in size until the establishment of the Mongol Empire in the 13th century. In 750 the Caliphate clashed with the Tang China at Talas. By this time only these two Empires stretched between the Atlantic and the Pacific.

681–1018 CE and 1185–1396 CE (548 years, 1269-554 BA): The Bulgarian Empire wherein it acted as a key regional power occurred in two distinct periods: between the seventh and eleventh centuries, and again between the twelfth and fourteenth centuries. The two "Bulgarian Empires" are not treated as separate entities, but rather as one state restored after a period of Byzantine rule over its territory.

692–1574 CE (882 years, 1242-376 BA): Ifriqiya, medieval empires of, (Aghlabid Empire, Zirid Empire, Tulunid, Fatimid, Hafsid Empire. Ifriqiya was a medieval region that included present-day Tunisia, eastern Algeria, and western Libya. The word Ifriqiya is Arabic for “Africa”. Created by early (692 conquest of Carthage) Islamic expansion from the east. Multiple Muslim dyansties persisted until 1574, when Ifriqiya became an Ottoman province.

697–1797 CE (1,100 years, 1253-153 BA): Venetian Empire, a sovereign state and maritime republic in parts of the present-day Italian Republic, Istria and Dalmatia. Centered on the lagoon communities of the prosperous city of Venice, it incorporated numerous overseas possessions in modern Croatia, Slovenia, Montenegro, Greece, Albania and Cyprus. The republic grew into a trading power during the Middle Ages and strengthened this position during the Renaissance. Most citizens spoke the Venetian language, although publishing in Italian became the norm during the Renaissance. The opening of new trade routes to the Americas and the East Indies via the Atlantic Ocean marked the beginning of Venice’s decline as a powerful maritime republic. The city-state also suffered defeats at the hands of the navy of the Ottoman Empire. In 1797, the republic was plundered by retreating Austrian and then French forces, following an invasion by Napoleon Bonaparte.

698–926 CE (228 years, 1248-1024 BA): Parhae, Balhae, a multi-ethnic kingdom established in 698 and originally known as the Kingdom of Jin (Zhen) until 713 when its name was changed to Balhae. At its greatest extent it corresponded to what is today Northeast China, the northern half of the Korean Peninsula and the southeastern Russian Far East. Balhae survived as a distinct population group before disappearing under Mongol rule.

699–766 CE (65 years, 1249-1184 BA): Türgesh Khaganat, a Turkic tribal confederation. Once belonging to the Duolu wing of the Western Turkic On Oq elites, Türgeshes emerged as an independent power after the demise of the Western Turks and established a khaganate in 699. The Türgesh Khaganate lasted until 766 when the Karluks defeated them.

700–1900 CE (1200 years, 1250-50 BA): Kanem-Bornu Empire, from 700 as Kanem Empire to 1380 and as Bornu Empire until 1900, a slave trading empire that existed from the 9th to the 19th century. It was ruled by the Sef (Sayf) dynasty and controlled the area around Lake Chad. The empire’s territory included parts of what are now Chad, Cameroon, Nigeria, Niger, and Libya. Region taken from prior Sao culture. Slaves, mostly young women and girls, were imported from the south of Lake Chad by raiding, and then transported to market, where the slaves were traded for horses and weapons. Fortified settlements genocidally destroyed. The annual number of slaves traded increased from 1,000 in the 7th century to 5,000 in the 15th totally 2 million.

711–1492 CE (548 years, 1269-554 BA): Al-Andalus (Muslim Conquest of Iberia), 711–1492, the name is used by modern historians for the former Islamic states in modern Spain, Portugal, and France. The name describes the different Muslim states that controlled these territories at various times between 711 and 1492.

730–1036 CE (306 years, 1220-914 BA): Gurjara-Pratihara (Pratihara) Empire, ruled much of Northern India, were instrumental in containing Arab armies moving east of the Indus River. By the end of the tenth century the Gurjara-Pratihara domains had dwindled to a small state centered on Kannauj.

750-1162 CE (412 years, 1200-788 BA): Pala Empire, India, were astute diplomats and military conquerors. Their army was noted for its vast war elephant corps.

Settlements became common by 3-4 thousand years ago and some coastal tribes developed war canoes able to hold up to 60 warriors each. Armadas of war canoes enabled conquest of other less aggressive coastal peoples, i.e. empire-building was enabled by red cedar canoe technology and weapons such as tethered rocks that could be heaved at 'enemy' canoes attempting to protect their settlement to sink them. Those few who became war-like were selected for. Their success was at the expense of those who had been living peaceably for thousands of years (as usual) and they soon normalized their behavior. The raiders enslaved and exploited the conquered who adapted as evidenced by a rapid increase in the number of occupied forts after 1000 BA. Smallpox reduced the regional population about 90 percent in the late 18th century, followed by European migration mainly via the Oregon Trail.

A policy of expansion towards the Balkan Peninsula and the lands east of the Carpathian Mountains, transformed the kingdom into one of the major powers of medieval Europe. The kingdom received a major blow from the Mongol invasion of 1241–42. The erection of fortresses by landlords after the withdrawal of the Mongols, led to the development of semi-autonomous “provinces” dominated by powerful magnates.

The following decades were marked by the Black Death, as well as numerous invasions that devastated the country’s economy, population, and urban centers. The Kingdom’s geopolitical situation further worsened after the conquest of the Byzantine Empire and the Empire of Trebizond by the Ottoman Turks. As a result of these processes, by the end of the 15th century Georgia turned into a fractured entity. This whole series of events also led to the final collapse of the kingdom into anarchy by 1466 and the mutual recognition of its constituent kingdoms of Kartli, Kakheti, and Imereti as independent states between 1490 and 1493 — each led by a rival branch of the Bagrationi dynasty, and into five semi-independent principalities.

He obtained weapons from Europe, then mobilized the Toucouleur to pursue an Islamic holy war in 1854 against the non-Muslim ethnic groups and those Muslims who had strayed. The Toucouleur armies succeeded. The Toucouleur Empire grew and extended from Senegal to much of Mali over the next ten years. His son Mustafa reigned over this empire and the Toucouleur between 1864 and 1870, followed by Omar’s second son, Ahmadu Tall a “Toucouleur-Muslim despot” over the Mandinka people and Bambara people. The empire collapsed in the 1880s as the Fulani, Tuaregs and the Moors attacked the Toucouleurs, and a civil war between local Toucouleur leaders engulfed the region. The empire ended in 1891, after the French colonial forces invaded the region.

1799–1846 CE (47 years, 151-104 BA): The Sikh Empire was established in the Punjab region of India. The empire collapsed when its founder, Ranjit Singh, died and its army fell to the British.

1804–1814 CE (10 years, 146-136 BA): The First French Empire was the empire of Napoleon Bonaparte of France and the dominant power in much of continental Europe at the beginning of the 19th century.

1804–1818 CE (14 years, 146-132 BA): Austrian Empire (1804 to 1867); Austro-Hungarian Empire (1867–1918), during its existence, it was the third most populous monarchy in Europe after the Russian Empire and the United Kingdom. Along with Prussia, it was one of the two major powers of the German Confederation. Geographically, it was the third-largest empire in Europe after the Russian Empire and the First French Empire.

1818–1862 CE (44 years, 132-88 BA): The Massina Empire, was one of the most organized theocratic states of its time on the African continent. It was ruled by an almami with the help of a Grand Council that possessed the power to elect new rulers after the death of the previous one. While, in theory, the almami did not have to be a member of the Bari family, but only someone who was learned and pious, every almami elected happened to be a son of the previous ruler.

1822–1889 CE (67 years, 128-61 BA): Empire of Brazil, a 19th-century state that broadly comprised the territories which form modern Brazil and (until 1828) Uruguay. Its government was a representative parliamentary constitutional monarchy under the rule of Emperors Pedro I and his son Pedro II. A colony of the Kingdom of Portugal, Brazil became the seat of the Portuguese Empire in 1808, when the Portuguese Prince regent, later King Dom John VI, fled from Napoleon’s invasion of Portugal and established himself and his government in the Brazilian city of Rio de Janeiro.

1852–1870 CE (18 years, 98-80 BA): The Second French Empire was the Imperial Bonapartist regime of Napoleon III.

1868–May 3, 1947 CE (79 years, 82-3 BA): The Empire of Japan, at its maximum extent in 1942, was the historical Japanese nation-state that existed from the Meiji Restoration in 1868 to the enactment of the 1947 constitution of modern Japan, part of the Euro-Sino Empire, that serves commercial interests.

1871–1918 CE (47 years, 79-42 BA): The German Empire, another "heir to the Holy Roman Empire."

1882–1947 CE (65 years, 68-3 BA): The Italian (colonial) Empire, ending in Fascism. Founded in Africa in the 19th century comprised the colonies, protectorates, concessions and dependencies included in the territories of present-day Libya, Eritrea, Somalia and Ethiopia.

1884–1920 CE (65 years, 66-30 BA): German Colonial Empire, states unified in 1871, the chancellor of this time period was Otto von Bismarck. Short-lived attempts at colonization by individual German states had occurred in preceding centuries, but Bismarck resisted pressure to construct a colonial empire until the Scramble for Africa in 1884. Claiming much of the remaining uncolonized areas of Africa, Germany built the third-largest colonial empire at the time, after the British and French. The German colonial empire encompassed parts of several African countries, including parts of present-day Burundi, Rwanda, Tanzania, Namibia, Cameroon, Gabon, Congo, Central African Republic, Chad, Nigeria, Togo, Ghana, as well as northeastern New Guinea, Samoa and numerous Micronesian islands. All colonies disestablished in 1920 post WWI.

1897–1920 CE (23 years, 53-30 BA): Dervish State (Somali), a territory in the Horn of Africa established by Mohammed Abdullah Hassan, a Muslim religious leader and spiritual leader to his Somali followers. The Dervish State was a mobile proto-state with shifting boundaries and a fluctuating population. It was one of the longest and bloodiest militant movements in sub-Saharan Africa during the colonial era, overlapping with World War I.

1908-1962 CE (54 years, 42 BA-12 AA): Belgian Empire, overseas territory was just one colony (about 76 times larger than Belgium itself) — known as the Belgian Congo. The colony was founded in 1908 following the transfer of sovereignty from the Congo Free State, which was the personal property of Belgium’s king, Leopold II. The violence used by Free State officials against indigenous Congolese and the ruthless system of economic extraction had led to intense diplomatic pressure on Belgium to take official control of the country. Belgian rule in the Congo was based on the “colonial trinity” (trinité coloniale) of state, missionary and private company interests.

1933-1945 CE (12 years, 17-5 BA): Nazi Germany, Heil Hitler!

1949-present (75+ years, 1 BA+): China, People’s Republic of, 1949 to present.

1949-1991 CE (42 years, 1 BA-41 AA): Soviet Empire, an imperialist colonial power maintaining a socialist façade.

2001 CE (51 AA): IS, Islamic State, a belief based empire committed to conquer the Euro-Sino Empire. Like the 844 year Holy Roman Empire, neither holy, Islamic, nor an Empire-as-usual other than of belief. It may or may not last longer.

2009 CE (59 AA): BRICS, (Brazil, Russia, India, China, South Africa, and then Iran, Egypt, Ethiopia and the United Arab Emirates), to counter Western hegemony.

2013 CE (63 AA): China B&R, People's Republic of China Belt and Road Initiative: infrastructure development and investments in 152 countries and international organizations in Asia, Europe, Africa, the Middle East, and the Americas.

2015 CE (65 AA): FoW, Federation of Watersheds: in idea only, an evidence-based civilization/control SYSTEM ruled by natural law committed to replacing all belief-based SYSTEMs and unsustainable growth/empire-building SYSTEMs with an ecological civilization that works long-term per Nature as choicelessly managed by servants of the planetary life-support system who listen to Nature.

Byzantine Dark Age, 150 years, 630 – late 8th centuries
Dark Age of Khmer, 432 years, 1431 – 1863 CE

On average, 290 years on the downslope, 11 to 12 generations, before rebuilding/regrowing (for a time) to repeat the pattern. But collapse without conquest and with no recovery/rebuilding is four times more common. A global empire has no outliers to subsume it (assuming the Klingons don't show up), so collapse to dissolution without recovery is a more than possible future. If no recovery (see below), dissolution to local extinction takes longer, so maybe the downslope without recovery takes 20 generations (500 years), but as no history is written, the time needed for a global civilization to collapse to recovery, extinction, or renormalization (if possible) is unknown.

Collapse of empire not followed by conquest (often quickly) by an outlaying upstart empire builder has about a 1:5 chance of collapse to a Dark Age with (some) recovery (before repeating the pattern), and an 80% chance of collapse to a Darker Age ending in local extinction. The collapse of the Euro-Sino Empire, the first global empire (quite possibly the last global empire), will not be conquered from without by Klingons, and local extinction will be an on Earth extinction, so if Elon Musk retires on Mars, he and his servants may be the only humans left (but I’m hoping for extinction) or some humans endeavoring to renomalize may manage to persist.

If a marauding horde culture develops during collapse, and the dynamic of the downslope death-spiral lasts 200 to 600 years, any remnant populations of quasi-functional renormalizing humans who somehow manage to persist for 200 years, will be viewed as resources for the taking by our BAU descendants. The remnant population will be so dysfunctional as to fail to reproduce after 8 to 24 generations on the downslope. The Indus Valley Civilization's darker age was the largest collapse event known and most cities were abandoned within 200 years (2023, 57% of global population is in urban areas, 83% of USA population is in urban areas, and if mostly depopulated in two hundred years, not good news for rural populations viewed as resources for the taking). The next will be global and duration of downslope likely to compare to that of the Indus Valley's 600 years on the downslope leading to complete dissolution after 24 generations. Going from over 8 billion to whatever, if any, may take longer, e.g. 1k years or 40 generations. How many generations on the downslope the last literate Harappan lived, failed to pass on their literacy, is unknown (2-3?).

Keep in mind that many small regional "empires" have come and gone in the last 12,000 years without archaeology noting or history naming them, many more than the 133+ named above. Of all the empires, likely all at their height, deeply believed they would be the exception. Per the nature of things, the universe doesn't care what humans believe.

History will be in the mind of future historians. If humans stop committing empire, such as by forming a Federation of Watersheds, perhaps 20,000 in number instead of 200 nation-states, that has a shared mobile military force to prevent the temporarily stronger from invading the weaker (see above), then Federation historians, unlike those of the 18th - 21st centuries, will not endeavor to normalize patriarchy, wealth inequality, acquisitiveness, war, alpha maleness, growth, elite privilege, conspicuous consumption, destruction of planetary commons, genocide, mass extinction, and empire-building, aka buisness-as-usual.

From the hunter-gatherer POV spanning 300,000 years, the recent 8,000 years of empire-building would seem aberrant. If humans transition into a stable and sustainable Federation, living the ecolate life in balance and harmony with Nature, then empire-building will seem aberrant again.

The current empire is the Euro-Sino Empire dominated by commercial interests, which subsumed most nation-states by the mid twentieth century. As the first global empire, there are no other upstarts on the planet to conquer it when it weakens other than empires of belief. Like that of the Indus Valley, the Euro-Sino Empire can only collapse from within. Many empires have ended in conquest or internal revolt, but in all cases their rapid fall was the perhaps merciful "kicking in of a rotten door." The weakening may be from excessive elite demands on distant commoners, excessive demands on environmental carrying capacity, or both. "Excessive" equals the endeavor to grow without limit, for the rich to get richer.

The first empires were empires of belief. When agriculture allowed an area to support many more humans than hunter-gatherers, the agriculturalists, whether plant (Mesopotamia, Indus Valley, et al.) or animal based (Indo-Europeans, Mongol), displaced them, like it or not, to become agrarian empires. The large populations supported armies and those agrarian empires who transition to military empires replace those who do not, like it or not. Empires that spread by use or threat of force develop into city-states—political empires that evolve into nation-states whose development climaxed mid-20th century. All empires have been a mix of power: the power of religious belief, economic power, political power, and military force. The Euro-Sino Empire is a global industrial economic empire in that commercial interests dominate religious, political, and military interests.

The power basis for nomadic hunter-gatherers is a small section of environment within a day's walk. In the late Pleistocene the size of nomadic bands was limiting, so only empires of shared belief could develop in the late Pleistocene whose power base is the believing mind. Agriculturalists are initially small tribes depending on local environment for power also, but agriculture may allow the same area to support ten times the population. Hunter-gatherers in an area that can support agriculture (plant or animal based) that do not choose to become farmers/herders, are displaced (genocide/assimilation). Agriculturally developed areas support settled villages that develop into chiefdoms ruled by the stronger chief. Empires of belief join forces with agrarian empire builders.

Agro-powered empires spread throughout the local area that supports agriculture, the power base. Regional agro-politico-religio-belief empires can support mobile armies and navies to develop into city-nation-state building empires. When the Industrial Revolution began, a new power source for empire-building arose. Initially fossil-fueled growth strengthened the nation-state empire builders, especially the British Empire as that is where the fossil-fueled industrial society arose to spread throughout Europe then shifted to resource richer America as Europe was used up. As America was increasingly used up in the 20th century, growth shifted to India and China, mainly the Sino region that currently uses over half of the remaining coal resources to grow commercial empire at 7% to 10%, unsustainably doubling their consumption every 7 to 10 years. China is currently importing vast amounts of resources much as America did in the 20th century. Africa and Australia are being used up by the Euro-Sino Empire. When the planet is "taken" there is no Planet B, so without more energy and other resources to exploit, the industrial society, now global, will transition to descent as all prior ones have.

The future is constrained by power and vision. If the first global empire collapses, as the Indus one did, environmental resources will slowly accumulate as nature recovers. There will be no fossil fuels, however, to fuel another industrial empire. Environmental restoration will eventually allow for agro-powered empire-building and the pattern of rise and fall can continue. Or not.

Alternative to rise and fall is to acquire an illimitable non-fossil fuel power source. Techno-optimists firmly belief this will happen. If so, humanity will continue to grow and after the Milky Way is used up, our Borg-like descendants will endeavor to consume other galaxies. Or not.

Alternative to becoming Morlock/Borg-like (see above), humans could become Federation-like. The Kogi, who have transitioned into ecolate humans, are alternative. A sustainable Kogi-like life is possible and alternative to the Borg-like growther culture that has dominated human life for five thousand years. The Federation alternative combines the ecolate lives of our pre-empire-building ancestors with technology in studied moderation. The legacy of our overgrowth is the information acquired in the past seven thousand years. Preservation of information and minds able to access it is of highest priority as without it there can be no macroscope. Solar powered IT may be the only high-tech needed or supportable. Without thought there can be no life (sustainable). As Emerson noted, "Things are in the saddle and ride mankind" so far. Alternative is to put a Kogi-like consensus of ecolate thought in the saddle as a naturocracy. The dominant humans in the past five thousand years have acted like a bunch of kids with machetes (imagine giving every kid in an elementary school a machete and all adults leave until the next day—in 24 hours no one would starve, but expect fatalities). Humans might do better to defer to human intelligence as best it can be manifested to set limits by listening to Nature and provide best-guess direction towards a managed commons.

Peter Turchin's Secular Cycles 2009

Modern techno-industrial fossil fueled monetary society different from prior complex agrarian societies, but not foundationally. Complex society is now global, intertwined, and dependent on fossil fuels and agriculture whose productivity is largely dependent on turning fossil fuels into food. All hydroelectric dams were built usig fossil fuels, as are wind turbines, nuclear power plants, and solar PV that add to without replacing fossil fuel dependence.

From Alice Friedemann's a more detailed list of the phases derived from the table at the end of Chapter 1 in Secular Cycles:

Expansion Phase (growth)

Stability and peace leads to prosperity
Grain reserves are high, so crop failures don’t have much effect
Wages are high, commoners can rent farmland cheaply
Cities are small, artisans few, trade level low,
Prosperity leads to population growth
The elites exist but there aren’t many and they have a pretty modest lifestyle because peasant wages are so high.
The number of towns and land farmed grows
The elites don’t own large amounts of land yet
The state government is well financed from increasing taxes and ideas about going to war are growing
The overall outlook is one of optimism

Stagflation phase (compression)

Population growth continues, but the rate slows down, yet still overpopulation is reached, just as Malthus predicted, and the carrying capacity – the number of people who can occupy the land – is exceeded.
This problem is “solved” by the excess children without land moving to towns and cities.
Cities are cesspools of disease and many die, but no problem, there are always excess children from farms to replace them
Towns and cities grow, craftsmen and trade flourish
The Elites — the top one to two percent of the population — enter a golden age because they can charge high rents/prices for all of the basic necessities: food, housing, land, etc., and at the same time, pay low wages. No wonder the wealthy elites in America are so pro-immigration and against birth control and abortion. In every civilization that has ever existed, without exception, the elites only grow fabulously wealthy at this point in the cycle when they can pay low wages and charge high rents.
The amount of land owned by the wealthy is increasing
Some segments of the elite consume conspicuously.
Meanwhile the commoners in towns, cities, and on farms are all experiencing decreasing wages and increasing costs of living. Land prices are high. Misery, the homeless, debt, and poverty are increasing. Grain reserves are declining.
The rich and powerful over-reproduce too, so there are fewer lucrative opportunities for their children
The rich start to compete with each other. How this happens varies. In some there might be more duels, or more lawsuits. If there are government jobs that are especially lucrative, the competition to get into the best schools and to get the best government jobs grows intense.
The elites also try to get the government to give them money, to stop taxing them at all or lower their taxes
Which results in the peasants being taxed even more to make up for the lowered taxes on the rich
The government and internal order is till okay but starting to unravel, the general outlook grows more pessimistic and critical.
The government may try to solve these problems by invading nearby countries, or provide more food by building irrigation and roads
There is often a rise in the rate of crime in this pre-crisis period

Crisis Phase (state breakdown)

Trade starts to decline due to political unrest
Cities are at their highest levels of population
A few large landowners own most of the land. Sounds like now: In America (2013), the top 10 landholders own 2% of the land. In California (1973), just 25 landowners hold 16% of the land.
Debt is high, the price of food is high, and the grain reserves are gone
Very high inequality between the rich and poor, subsistence crises increase as food shortages happen more often
The populace, weakened by malnutrition and hunger, easily succumbs to epidemics (i.e. antibiotic resistant diseases in the future like TB, etc).
In the country and city, peasants rebel, demand reforms such as land redistribution
The elites have very high levels of corruption.
The elites may begin to wage wars against each other
The population starts to decline
The government goes bankrupt since no one is paying taxes, and loses control of the army and other institutions
The government collapses

Depression

It can take several iterations for an empire to completely fail.
Within the disintegration, there are also “fathers-and-sons” cycles: war and peace and war. These civil wars consume a state until the survivors and their children are so tired of war that peace and stability finally return. But the grandchildren who never experienced the reality of war start new wars. This cycle tends to happen every 40 to 60 years.
At the bottom the population is low, there’s lots of free land or cheap land, grain and other food vary in availability and price
The depression goes on for a long time because social cohesion has been lost and isn’t easily regained, fighting continues, and this is often when outside conquerors invade and conquer
The rich have gotten their comeuppance and declined from civil wars between themselves and are consuming a lot less, own less land than before, lots of downward mobility with the elite becoming commoners again
The state keeps trying to reinstate order but usually fails, and this is often when nearby nations invade to take advantage of the collapse
Trade is local, long-distance networks are broken
The outlook is very pessimistic
After enough time, stability and peace come back and the cycle starts all over again.

A September 2023 update.
Apparently exceeding carrying capacity is not a planetary limit, in Rockström's science,
which is why human/livestock populations cannot exceed limits.

Collapse: The Overpulsing (into overshoot) Paradigm

Existential issues facing humankind today (based on systems ecology, Jared Diamond's list of 12 environmental issues, Calhoun's rats of NIMH, and the list of planetary boundaries):

Energy longage of demand: Growth.
Biodiversity loss, mass extinction (Impact).
Oversized human/livestock/pet/crop populations (Population).
Overconsumption of planetary life-support system and growing behavioral sink (Affluence).
Fossil-fueled technology enabled industrial sprawl (Technology). deforestation, overcropping, urban overgrowth.
Changes set in motion during the Anthropocene (Systemic feedbacks):
Soil loss secondary to over salinization, soil mining, and erosion rates exceeding soil formation rates.
Overuse of freshwater resources: construction of dams, levees, jetties; unsustainable use for irrigation and any pumping which lowers a water table.
Buildup of biotoxins in the environment, including nitrogen and phosphorus as biosphere toxins.
Over-extraction of animal resources by human predators not living in a state of Nature (36% of mammalian biomass is humans and 60% is livestock).
Effects of introduced species: human, animal, or plant on native biomes.
Ocean acidification and plasticization.
Effects of anthropogenic climate change—politicized, hence a distraction (from other issues of greater concern).

I.e. reduce energy demands such that fossil fuels are irrelevant.
And DEMAND rapid depopulation (a real solution) NOW!
To counter the misinformation that climate change
is the number one problem, I confess to being
disingenuous. I would actually put climate
change at #7-#10. Written 4/15/19,
so I guess that makes me a
counter-revolutionary.
Listen to Nature.
LISTEN!

Fourth Law of Energetics

Nature selects for [through the process of trial and error] self-organizing, complex, open thermodynamic systems [including complex societies] that persist by maximizing empower [MePP, Odum's version of MPP] within a pulsing paradigm. K-strategists that overpulse to maximize short-term empower, that end up destroying/degrading the system that contains them, are selected against long term. Life on Earth is the outcome. Cancer and empire are short-term pathologies. Not all complex societies build empires. For industrial humans to persist in a viable form, they will have to understand their pathology and seek out the condition now that will come anyway, i.e. live as K-strategists by foundationally different rules of the game (a social contract) that select for behavior that works long term as Nature (who has all the answers) determines. Humans don't get a vote.

Zeroth Law: If the heat energy of two systems are each in thermal equilibrium with a third one, then they are in thermal equilibrium with each other. (You must play the game.)
First Law: Heat is. Energy cannot be created or destroyed. (You cannot win.)
Second Law: Change requires energy to be transformed into heat. "Things fall apart."—W.B. Yeats. (You cannot break even.)
Third Law: As heat approaches absolute zero, movement approaches zero, but absolute-zero is an imaginary state. You cannot stop movement; you cannot change a system into what it is not. (You cannot get out of the game.)
Fourth Law: Nature selects for self-organizing, open thermodynamic systems that persist by maximizing empower within a pulsing paradigm. (You cannot pulse sustainably if boundaries/thresholds are transgressed, e.g. cancer and empire building.)
Fifth Law: In complex open systems an energy hierarchy forms with higher quality energy (of higher Transformity) enabling the complexity via a network of energy feedback loops that maximize empower. (You cannot change just one thing in a complex system.)
Sixth Law: System pulsing in an energy hierarchy depends on a flow of materials enabled by the quality of energy used in the flow. (You cannot live by energy alone.)
Seventh Law: In complex monetary societies money flows opposite to real wealth, and its value is counterfeit. (You cannot get richer. You can have enough, but MORE! impoverishes in the long run. To want more than you actually need is a pathology, e.g. an osprey that eats more fish than it needs [to maintain flyable body weight] just because it can without knowing when to stop, or anyone living in modern techno-industrial society. To not know your wants from your needs is true ignorance, is to be a denizen of the consumer society [for a time] as a hu-man of NIMH circling a behavioral sink.)

'The third part of the “blindingly obvious” trilogy is that money acts only as a "claim" on the output of the real (energy) economy. Money has no intrinsic worth, and has value only in terms of the things for which it can be exchanged. No amount of money – be it currency, gold or any other token – would be of any use whatsoever to somebody stranded in the desert, or cast adrift in a lifeboat.' The Surplus Energy Economy 2020.

And all concepts are counterfeit too, for essentially the same reason. They make claims about the What-is, Nature, but are not the 'thing itself' as subsystem of and within multiple hierarchies of 'things' on down to the quantum and up to Cosmos. The voices in our heads, the sounds larynx make, or characters in a long string are at best representations of what matters (and energizes). Virtually all human prattle is delusional as the primates emitting it think their verbal behavior means something (intrinsically), i.e. is not counterfeit like their money which clothed apes also pretend matters. We storytelling animals deeply believe our thoughts and words (and money) have intrinsic worth.

We (or someone) may experience a 'sense of wonder' or 'enlightenment' and then turn it into a concept having, absolutely for sure, 'intrinsic value' as we, Lord Man, decree (or imagine some higher power has bestowed the 'intrinsic value'). Humans have constructed the palatial worlds they live in (as "the hollow men" in death's dream kingdom) by incessant concept mongering, elevated to such heights as wordsmithery can dissemble, but all beliefs, all consensus narratives are counterfeit and we would-be emperors have no clothes. We no more 'know' what matters, the What-is, than a dog can know calculus. Hu-mans need to stand down to persist, or when we are taken down, to know humilitas and remain in our place as evolvable subsystems of Gaia (instead of overpulsing, for a time, as dissipative structures operating far from thermodynamic equilibrium).

Most modern humans alive today are the last of 15,000 generations spanning the last 375k years. We alive today are 6.5% of all humans (123 billion) who have ever lived. We live in 0.02% of the time humans have been living on Earth. We do not live in normal times, nor are we normal humans. On our watch, we are presiding over the greatest mass extinction event since the late Cretaceous, one that could come to rival that of the Permian (we could become part of it). Perhaps coming to love and understand the planet and learning to live with it properly is to consider. A Great Selection is in the offing.
