1177 B.C.: The Year Civilization Collapsed

The Late Bronze Age Mediterranean was a densely interconnected trade network — Egypt, the Hittite Empire, Mycenaean Greece, Cyprus, and others exchanged tin, copper, grain, and diplomatic correspondence in a system as globalized as anything before the modern era. Cline marshals archaeological and climate evidence for multiple, roughly simultaneous stresses around 1200–1150 B.C.: prolonged drought reducing agricultural surplus, a cluster of major earthquakes, internal rebellions, and disruptive migrations (including the 'Sea Peoples'). No single shock was necessarily fatal on its own — Bronze Age civilizations had weathered individual crises before — but Cline argues the system's very interconnectedness, which had been a source of shared prosperity, became a liability once several shocks hit simultaneously, since trade disruption in one node cascaded into famine, unrest, and state failure in others that depended on it. The result was a systems collapse rather than a single military defeat, and it took the Eastern Mediterranean centuries to recover comparable complexity.
