The Bronze Age collapse is a transition in southwestern Asia and the Eastern Mediterranean from the Late Bronze Age to the Early Iron Age that some historians believe was violent, sudden and culturally disruptive. Cultural collapse of the Mycenaean kingdoms, the Hittite Empire in Anatolia and Syria, Egyptian Empire in Syria and Canaan interrupted trade routes and severely reduced literacy. In the first phase of this period, almost every city between Troy and Gaza was violently destroyed, and often left unoccupied thereafter: examples include Hattusa, Mycenae, Ugarit.
