The Bronze Age came to a close early in the twelfth century b.c. with one of the worst calamities in history: over a period of several decades, destruction descended upon key cities throughout the Eastern Mediterranean, bringing to an end the Levantine, Hittite, Trojan, and Mycenaean kingdoms and plunging some lands into a dark age that would last more than four hundred years. In his attempt to account for this destruction, Robert Drews rejects the traditional explanations and proposes a military one instead.
