Across the centuries, mighty kingdoms have crumbled, magnificent cities have fallen into ruin, and once-powerful civilizations have disappeared from the political map. From the lost Anglo-Saxon kingdoms and the destruction of Carthage to the collapse of the Hittite Empire, the decline of the Khmer Empire, and the abandoned cities of the ancient Maya, explore the societies whose fortunes were transformed by warfare, environmental pressures, political upheaval, and changing patterns of settlement. Discover the rulers who fought to preserve their kingdoms, the conflicts that brought dynasties to an end, and the archaeological discoveries that have helped recover forgotten histories. Beneath ruined temples, deserted fortresses, and buried cities lie the stories of civilizations whose political power vanished, but whose legacies continue to shape our understanding of the past.
