The book focuses on Cline's hypothesis for the Late Bronze Age collapse of civilization, a transition period that affected the Egyptians, Hittites, Canaanites, Cypriots, Minoans, Mycenaeans, Assyrians and Babylonians; varied heterogeneous cultures populating eight powerful and flourishing states intermingling via trade, commerce, exchange and "cultural piggybacking," despite "all the difficulties of travel and time".[1] He presents evidence to support a "perfect storm" of "multiple interconnected failures," meaning that more than one natural and man-made cataclysm caused the disintegration and demise of an ancient civilization that incorporated "empires and globalized peoples."[1][2] This ended the Bronze Age, and ended the Mycenaean, Minoan, Trojan, Hittite, and Babylonian cultures.[2]
Before this book, the leading hypothesis during previous decades attributed the civilizations' collapse mostly to Sea Peoples of unknown origin.[1][2][3][4]
