3.2 ka BP Megadrought and the Late Bronze Age Collapse

The collapse of Bronze Age civilizations in the Aegean, southwest Asia, and the eastern Mediterranean 3200 years ago remains a persistent riddle in Eastern Mediterranean archaeology, as both archaeologists and historians believe the event was violent, sudden, and culturally disruptive. In the first phase of this period, many cities between Pylos and Gaza were destroyed violently and often left unoccupied thereafter. The palace economy of the Aegean Region and Anatolia that characterized the Late Bronze Age was replaced by the isolated village cultures of the Dark Ages. Earthquakes, attacks of the Sea Peoples, and socio-political unrest are among the most frequently suggested causes for this phenomenon. However, while climate change has long been considered a potential prime factor in this crisis, only recent studies have pinpointed the megadrought behind the collapse. An abrupt climate shift seems to have caused, or hastened, the fall of the Late Bronze Age world by sparking political and economic turmoil, migrations, and famines. The entirety of the megadrought’s effects terminated the Late Bronze Age in the eastern Mediterranean.
