History12 - Russia and the Soviet Union 1914-1945 (WWI-WWII): Stalinism vs Leninism

Stalinism, the method of rule, or policies, of Joseph Stalin, Soviet Communist Party and state leader from 1929 until his death in 1953. Stalinism is associated with a regime of terror and totalitarian rule.

Leninism, principles expounded by Vladimir I. Lenin, who was the preeminent figure in the Russian Revolution of 1917. Whether Leninist concepts represented a contribution to or a corruption of Marxist thought has been debated, but their influence on the subsequent development of communism in the Soviet Union and elsewhere has been of fundamental importance.
