April 22, 1870 - Nikolai Lenin

Vladimir Ilyich Ulyanov (22 April [O.S. 10 April] 1870 – 21 January 1924), better known as Vladimir Lenin, was a Russian revolutionary, politician and political theorist.

Lenin embraced revolutionary socialist politics after his brother was executed in 1887 for plotting to assassinate Tsar Alexander III. 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. In 1897, Lenin was exiled to Siberia for three years, after which he moved to Western Europe including Switzerland and became a leading figure in the Russian Social Democratic Labour Party. In 1903, the party split between Lenin's Bolshevik faction and the Mensheviks, with Lenin advocating for a vanguard party to lead the proletariat in establishing socialism.
