In this volume, a distinguished group of scholars examine the national experiences of six major twentieth-century powers— the United States, Japan, Turkey, China, India and Germany—to discern the centuries’ legacies for today and the lessons for tomorrow. They explore core themes including anticolonialism, democracy, socialism, nationalism, industrialization, nuclear weapons, and globalization and provide their own personal interpretations of the century, as well as their respective nation’s experiences and historical memory of the era. Together, they provide a broad historical context of the forces that shaped the twentieth century that will be of interest to scholars and students of history as well as policymakers.
