In this episode of Crash Course World History, John Green explores the mysterious collapse of the Bronze Age civilizations in the Eastern Mediterranean around 1200 BCE. The video challenges the traditional narrative of separate, isolated civilizations by demonstrating how Egypt, the Hittites, the Mycenaeans, and others formed a highly interconnected international system defined by trade, diplomacy, and war. It examines the evidence for this interdependence, including the famous Uluburun shipwreck and the Amarna Letters.
