 According to Mellaart, in "The End of the Early Bronze Age in Anatolia and the Aegean" (1958), for reasons unknown, the Hittites moved into central Asia Minor, conquering the Hattians and later adopting their culture and name.This invasion by the Hittites displaced other peoples living in Anatolia, who in turn displaced the Middle Helladic Greek-speaking peoples to the west.This enforced an exodus from Northwestern Anatolia created a wave of refugees who invaded what is now southern Greece and destroyed the Early Helladic civilization.
