The Late Bronze Age collapse was a period of societal collapse in the Mediterranean basin during the late 13th to early 12th century BC. It is thought to have affected much of the Eastern Mediterranean and Near East, in particular Egypt, Anatolia, the Aegean, eastern Libya, and the Balkans. The collapse was sudden, violent, and culturally disruptive for many Bronze Age civilizations, creating a sharp material decline for the region's previously existing powers.
