Vladimir Lenin

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.

Born into a middle-class family in Simbirsk in the Russian Empire, Lenin embraced revolutionary socialist politics after his brother was executed in 1887 for plotting to assassinate the tsar. He was expelled from Kazan Imperial University for participating in student protests, and earned a law degree before moving to Saint Petersburg in 1893 and becoming a prominent Marxist activist.
