Book excerpt: Debates on Stalinism introduces major debates about Stalinism during and after the Cold War. Did 'Stalinism' form a system in its own right or was it a mere stage in the overall development of Soviet society? Was it an aberration from Leninism or the logical conclusion of Marxism? Was its violence the revenge of the Russian past or the result of a revolutionary mindset? Was Stalinism the work of a madman or the product of social forces beyond his control? The book shows the complexities of historiographical debates, where evidence, politics, personality, and biography are strongly entangled. Debates on Stalinism allows readers to better understand not only the history of history writing, but also contemporary controversies and conflicts in the successor states of the Soviet Union, in particular Russia and Ukraine.
