'Why did the twentieth century witness unprecedented organized genocide? Can we learn why genocide is perpetrated by comparing different cases of genocide? Is the Holocaust unique, or does it share causes and features with other cases of state-sponsored mass murder? Can genocide be prevented?' 'Blending gripping narrative with trenchant analysis, Eric Weitz investigates four of the twentieth century's major eruptions of genocide: the Soviet Union under Stalin, Nazi Germany, Cambodia under the Khmer Rouge, and the former Yugoslavia. Drawing on historical sources as well as trial records, memoirs, novels, and poems, Weitz explains the prevalence of genocide in the twentieth century - and shows how and why it became so systematic and deadly.' This book offers some of the most absorbing accounts ever written of the population purges forever associated with the names Stalin, Hitler, Pol Pot, and Milosevic. A controversial and richly textured comparison of these four modern cases, it identifies the social and political forces that produce genocide.
