This book presents a comprehensive analysis of the political thought of Joseph Stalin. Making full use of the documentation that has recently become available, including Stalin's private library with his handwritten marginal notes, the book provides many insights into Stalin and also into Western and Russian Marxist intellectual traditions. Overall, the book argues that Stalin's political thought is not primarily indebted to the Russian autocratic tradition but belongs to a tradition of revolutionary patriotism that stretches back through revolutionary Marxism to Jacobin thoughts in the French Revolution. It makes interesting comparisons between Stalin, Lenin, Bukharin and Trotskii and explains a great deal about the Stalinist era's many key problems, including the industrial revolution from above, socialist cultural policy, Soviet treatment of nationalities, pre-war and Cold War foreign policy, and the purges.
