Book excerpt: The horrors of the Nazi regime and the Holocaust still present some of the most disturbing questions in modern history: Why did Hitler's party appeal to millions of Germans, and how entrenched was anti-Semitism among the population? How could anyone claim, after the war, that the genocide of Europe's Jews was a secret? Did ordinary non-Jewish Germans live in fear of the Nazi state? In this unprecedented firsthand analysis of daily life as experienced in the Third Reich, What We Knew offers answers to these most important questions. Combining the expertise of Eric A. Johnson, an American historian, and Karl-Heinz Reuband, a German sociologist, What We Knew is the most startling oral history yet of everyday life in the Third Reich.
