Bronze Age collapse
Around 1200 BCE a perfect storm — drought, famine, trade collapse, migrations — broke the palace economies of the Eastern Mediterranean. Egypt survived pyrrhic battles. Mycenae and the Hittites did not.
The Late Bronze Age was an interconnected world — the Uluburun shipwreck and the Amarna letters are the physical and textual proof. Palaces traded bronze inputs, grain, and elite gifts across the Eastern Mediterranean. Within a few decades around 1200 BCE that system failed. Eric Cline’s popular framing, and much of the 2026 scholarly consensus the wiki carries, is multi-causal: no single villain, a stack of stressors that exceeded the most interdependent societies’ ability to recover.
The chain starts with climate. The 3.2 ka megadrought hit roughly 1220–1190 cal BC across the Eastern Mediterranean and Near East — pollen at Cyprus and coastal Syria, Nile flood records, Dead Sea levels dropped more than 50 meters, juniper rings in Anatolia show a severe dry spell around 1198–1196 BC. Drought drove crop failures; Cyprus and coastal Syria show the strongest correlations. Hittite famine appears in correspondence; Egypt sent grain north.
Trade breaks, people move
When palaces could no longer afford imports and ports became targets, the bronze-provisioning network broke down. Archives stop when palaces stop functioning — the breakdown is inferred from silence as much as from battle layers. Armed mass migrations followed, including the groups Egyptian records call the Sea Peoples — “as much victims as oppressors,” in Cline’s phrase. Egyptian inscriptions document their attacks during the collapse, not before it. Merneptah and Ramses III name nine distinct migrating groups.
Survival was uneven. Mycenaean Greece and the Hittite Empire collapsed completely. Egypt won battles in 1177 BCE but entered decline. Assyria and Babylonia maintained continuity. Cyprus and Phoenicia transformed rather than vanished — an “omega followed by alpha” cycle in adaptive-cycle language.
The same two words name a different story on the science wiki. David Reich, on a Dwarkesh podcast, says many immune and metabolic frequency trajectories intensify between about 5,000 and 2,000 years ago — density, animals, urban-ish living, not the first farms. That is a biology claim about bodies. It is not palaces burning around 1200 BCE, and it is not this chain.
