Vladimir Lenin, Russian revolutionary and founder of Soviet Russia (died 1924)

Vladimir Ilyich Ulyanov, better known as Vladimir Lenin, was a Russian revolutionary, politician and political theorist. He was the first head of government of Soviet Russia from 1917 until his death in 1924, and of the Soviet Union from 1922 until his death. As the founder and leader of the Bolsheviks, Lenin led the October Revolution which established the world's first socialist state. His government won the Russian Civil War and created a one-party state under the Communist Party. Ideologically a Marxist, his developments to the ideology are called Leninism.

The Russian Soviet Federative Socialist Republic, previously known as the Russian Socialist Federative Soviet Republic and the Russian Soviet Republic, and unofficially as Soviet Russia, was a socialist state from 1917 to 1922, and afterwards the largest and most populous constituent republic of the Soviet Union (USSR) from 1922 to 1991, until becoming a sovereign part of the Soviet Union with priority of Russian laws over Union-level legislation in 1990 and 1991, the last two years of the existence of the USSR. The Russian SFSR was composed of sixteen smaller constituent units of autonomous republics, five autonomous oblasts, ten autonomous okrugs, six krais and forty oblasts. Russians formed the largest ethnic group. The capital of the Russian SFSR and the USSR as a whole was Moscow and the other major urban centers included Leningrad, Stalingrad, Novosibirsk, Sverdlovsk, Gorky and Kuybyshev.
