The Nazi leader Julius Streicher and his propaganda newspaper Der Stürmer are still regarded as synonymous with anti-Semitism, a central element of National Socialism. Hitler himself noted that if one supports National Socialism, one must approve of Streicher. This book for the first time fully and in detail traces the political career of Streicher and the developmental stages of his magazine. In a dual biography, a comprehensive picture emerges of a despicable publication and its creator. Daniel Roos' book shows how Julius Streicher, elevated by National Socialism, significantly contributed to creating an anti-Semitic climate by mobilizing the bloodthirsty and pornographic fantasies of his readership, which prepared the ground for the later extermination actions.
