Holocene Epoch 26
12,000–10,000 BCMegafauna ExtinctionsWoolly mammoth and others disappearThe great megafauna — woolly mammoths, mastodons, cave lions, giant sloths — go extinct across the world, likely from a combination of climate change and human hunting.
~11,700 years agoYounger Dryas EndsIce age abruptly endsThe last cold snap of the Ice Age ends around 11,700 years ago; global temperatures rise 10°C in decades. Glaciers retreat, sea levels rise, and modern climate conditions begin.
~9,500 BCGöbekli TepeWorld's oldest temple complexHunter-gatherers in southeastern Turkey construct Göbekli Tepe — massive stone pillars in circles, predating agriculture. Suggests complex religion and social organisation far earlier than thought.
~9,000 BCAgriculture BeginsFarming invented in the Fertile CrescentHumans begin deliberately cultivating wheat, barley and lentils in the Fertile Crescent. The most transformative change in human history begins.
~9,000–8,000 BCFirst Domesticated AnimalsSheep, goats and dogs tamedSheep, goats, pigs and cattle are domesticated in the Middle East, providing reliable food, wool and labour.
~8,000 BCJericho FoundedOne of the world's first citiesJericho develops into one of the earliest permanent settlements, with mud-brick houses, a stone tower and defensive walls — remarkable for 9000 BCE.
~7,000–5,000 BCCatalhoyukLargest Neolithic cityCatalhoyuk in Turkey becomes one of the world's largest settlements with up to 8,000 inhabitants — a remarkable proto-urban society.
~7,000–5,000 BCPottery InventedFired clay vessels transform food storageCeramic pottery is independently invented in multiple regions, enabling cooking, food storage and trade.
~6,000–4,000 BCFarming Spreads to EuropeAgriculture reaches the MediterraneanFarming communities spread westward from Anatolia into Greece and the Balkans, then across Europe, displacing or absorbing hunter-gatherer populations.
~6,000–3,000 BCHolocene Climate OptimumEarth's warmest post-glacial periodGlobal temperatures peak 1-2°C above present. The Sahara is green with lakes and wildlife. African and Asian monsoons are stronger, supporting large populations in now-arid regions.
~6,000–2,000 BCSahara Green PeriodThe Green SaharaThe Sahara Desert is replaced by savannah, grassland and lakes, supporting hippos, crocodiles, elephants and large human populations. Rock art from this period survives across the region.
~5,000–4,000 BCCopper SmeltingFirst metal technologyHumans discover that copper ore can be smelted to produce metal tools — the first use of metallurgy. Marks the transition from Stone Age to Copper Age.
~3,500 BCFirst WritingCuneiform invented in MesopotamiaThe Sumerians develop cuneiform writing on clay tablets to record trade. The invention of writing marks the beginning of recorded history.
~3,500 BCWheel InventedTransformative transport technologyThe wheel is invented in Mesopotamia, initially for pottery then transport. Combined with the axle, it transforms trade, warfare and agriculture across Eurasia.
~3,000 BCBronze Age BeginsTin and copper alloyed into bronzeMetallurgists discover that adding tin to copper creates bronze — harder and more durable. Bronze tools and weapons spread across Eurasia, transforming warfare and agriculture.
~2,560 BCPyramids of GizaAncient Egypt's greatest monumentsThe Egyptian pharaohs construct the Great Pyramid of Giza — for 3,800 years the tallest structure ever built, representing the peak of Old Kingdom engineering.
~2,500 BCStonehenge CompletedIconic megalithic monumentThe final phase of Stonehenge is completed in southern England — massive sarsen stones with precise astronomical alignments, suggesting sophisticated calendar knowledge.
~1,200 BCIron Age BeginsIron replaces bronzeIron smelting technology spreads across the Old World, producing harder and cheaper tools than bronze. Iron ore is far more abundant than tin or copper, democratising metalwork.
500–300 BCClassical GreeceDemocracy, philosophy and scienceAncient Greece produces democracy, philosophy, drama and science. Socrates, Plato, Aristotle, Euclid and Archimedes lay the intellectual foundations of Western civilisation.
27 BC – 476 ADRoman EmpireLargest western empire of antiquityThe Roman Empire at its height controls 5 million km² and 70 million people, spreading Latin, Roman law and engineering across Europe, North Africa and the Middle East.
1347–1351 ADBlack DeathDeadliest pandemic in human historyThe bubonic plague kills 30-60% of Europe's population between 1347 and 1351. It reshapes European society, labour relations and the relationship between Church and state.
1440 ADPrinting PressGutenberg's moveable typeGutenberg's printing press (1440) revolutionises the spread of information, enabling the Protestant Reformation, the Scientific Revolution and the spread of literacy.
1760–1840 ADIndustrial RevolutionSteam power transforms civilisationThe Industrial Revolution begins in Britain around 1760, powered by steam engines and coal. It transforms manufacturing, transport and urban life, launching sustained economic growth.
1750–presentClimate CrisisHuman-caused global warming acceleratesBurning of fossil fuels raises atmospheric CO₂ to levels not seen in 3 million years, driving rapid global warming, sea level rise and extreme weather events.
1914–1945 ADWorld WarsTwo global conflicts reshape the worldThe First and Second World Wars (1914-18, 1939-45) kill over 80 million people and redraw the world map, leading to decolonisation, the United Nations and the nuclear age.
1960–presentDigital RevolutionComputing and the internet transform lifeComputers, the internet and smartphones create a new information age. By 2000, the world is more interconnected than at any point in history.
