Vladimir Lenin was one of the main figures of communism in Russia, as he was the leader of the bolsheviks and the founder of the Soviet Union.

Explanation:

Vladimir Lenin was a Russian communist politician and revolutionary, as well as a Marxist theorist, and the founder of the Soviet Union in 1922.

After the bourgeois revolution overthrew the monarchy in Russia in early 1917 and the new government wanted to maintain Russia's participation in the First World War, the Bolsheviks under Lenin's leadership conquered power in the October Revolution. They violently disbanded the constituent assembly and restricted freedom of expression. In the ensuing civil war, the Bolsheviks managed to control most of the territory of the former Russian Empire and to break the resistance of the White Army. Towards the end of the war, in 1922, the Bolsheviks founded the Union of Soviet Socialist Republics.
