Based on a trove of original documents that have only been released in the last 15 years, Stephen Kotkin, the John P. Birkelund '52 Professor in History and International Affairs, delves into some of history’s most captivating questions surrounding Stalin’s rule. Stalin (Penguin) provides answers about whether the famine of 1931-33 was a genocide directed at Ukrainians, solves Bolshevik leader Sergey Kirov murder, and examines closely the Hitler-Stalin pact, Stalin’s war against elites, and his entry into the Spanish civil war.
