"Stalin's Terror" is an academic book that explores the complex nature of mass repression unleashed under the leadership of Joseph Stalin in the Soviet Union between 1937 and 1938. The contributions come from British, Irish, Russian, American, German, and Austrian scholars who illuminate various aspects of this dark period in history. The book is divided into three main parts: the first part addresses the extermination policies against the Soviet elite and the Communist International. The second part focuses on the massive operations of the secret police (NKVD) against social outsiders, Poles, and other ethnic groups deemed "hostile." The concluding section contains micro-studies on targeted victim groups within the general population. This comprehensive analysis offers valuable insights into the mechanisms and impacts of repression during one of the most turbulent times in Soviet history.
