The Bronze Age Collapse

Around 1200-1150 BC the interconnected civilisations of the eastern Mediterranean fell within decades: the Hittite Empire vanished, Mycenaean Greece's palaces burned, Ugarit died mid-correspondence, and Egypt barely held off the 'Sea Peoples'. The favoured modern explanation is systems collapse — drought, migration, war, and broken trade compounding — and the crisis ushered in the Iron Age and the Greek Dark Age.

Key facts

When: c. 1200-1150 BC, eastern Mediterranean
Fell: Hittite Empire, Mycenaean palaces, Ugarit and many Levantine cities
Survived, diminished: Egypt (repelling the Sea Peoples under Ramesses III) and Assyria
The Sea Peoples: Migrating raider coalitions named in Egyptian records; origins debated
Leading explanation: Systems collapse: megadrought, famine, migration, war, trade failure
Famous casualty: Widespread literacy — Linear B vanished with the palaces
What followed: The Greek Dark Age; iron's spread; eventually the alphabet, Israel, Greece

The globalised Bronze Age

The late Bronze Age eastern Mediterranean was a connected world that would look familiar to a modern economist: great powers — Egypt, the Hittite Empire in Anatolia, Mycenaean Greece, Assyria, Babylon — bound by diplomatic marriages, royal correspondence (the Amarna letters read like a chancellery inbox), and above all trade: the Uluburun shipwreck (c. 1300 BC) carried Cypriot copper, Afghan tin and lapis, Baltic amber, Egyptian gold — one hull holding the whole system. Bronze itself embodied the interdependence: its tin travelled thousands of kilometres, and everything from ploughs to armies depended on the supply chains moving it.

The fall

Within roughly fifty years around 1200-1150 BC, the system died. The Hittite Empire — superpower enough to fight Egypt at Qadesh — vanished so completely that its existence had to be re-excavated in the 19th century; its capital Hattusa was abandoned and burned. The Mycenaean palaces — Pylos, Mycenae, Tiryns — burned within a generation, taking with them Linear B literacy: Greece forgot how to write for four centuries. The great port of Ugarit was destroyed so abruptly that desperate letters lay unsent in the kilns — the king writing that enemy ships had come and “the ships of my fleet are in the land of Lukka” — while city after Levantine city shows its destruction layer. Egypt survived, barely: Ramesses III’s temple walls record repelling the land-and-sea migrations of the “Sea Peoples” — a shifting coalition of displaced groups (the Peleset among them, generally identified with the later Philistines) whose origins remain the puzzle’s most argued piece — but the victory exhausted the New Kingdom, which shrank into division within decades.

Why

Single-cause candidates each fail alone: earthquakes (a documented “storm” of them), drought, invasion, internal revolt, the iron-versus-bronze arms argument. The consensus assembled since, crystallised by Eric Cline, is systems collapse: a decades-long megadrought (now measured in pollen and isotope records) driving famine and migration, which fed warfare and the Sea Peoples’ movements, which cut the trade routes, whose failure starved palace economies too specialised to absorb the shocks — a cascade in which the network that had made the powers rich transmitted their failure instead. The first collapse of a globalised system, studied with unmistakable side-glances at our own.

After the fall

The rubble incubated the next world: with palace monopolies gone, iron — workable from common ores — spread; the Phoenicians’ lean trading cities carried a radically simplified writing system, the alphabet, in place of palace syllabaries; and in the post-collapse hill country and islands emerged, in time, Israel and archaic Greece — the Dark Age’s exit ramps into the classical world. Civilisations, the episode’s standing lesson runs, are resilient against any one blow and mortal to five at once.
