Book excerpt: In examining one of the defining events of the twentieth century, Doris L. Bergen situates the Holocaust in its historical, political, social, cultural, and military contexts. Unlike many other treatments of the Holocaust, the revised, second edition of War and Genocide discusses not only the persecution of the Jews, but also other segments of society victimized by the Nazis: gypsies, homosexuals, Poles, Soviet POWs, the handicapped, and other groups deemed undesirable. In clear and eloquent prose, Bergen explores the two interconnected goals that drove the Nazi German program of conquest and genocide—purification of the so-called Aryan race and expansion of its living space—and discusses how these goals affected the course of World War II. Including first hand accounts from perpetrators, victims, and eyewitnesses, the book is immediate, human, and eminently readable.
