Vladimir Lenin

At the Second Congress of the Russian Social Democratic Labour Party in London, Lenin led a split that created the Bolshevik faction. The Bolsheviks advocated for a disciplined vanguard party of professional revolutionaries, a key element of Lenin's political strategy.

Lenin returned to Russia from exile and published the April Theses, calling for the overthrow of the Provisional Government, transfer of power to the soviets, and an end to World War I. This document set the Bolshevik agenda for the coming revolution.

Lenin led the Bolshevik seizure of power in Petrograd, capturing key government buildings and the Winter Palace. The revolution overthrew the Provisional Government and established the world's first socialist state, the Russian Soviet Federative Socialist Republic.

Lenin signed a separate peace treaty with the Central Powers, ceding vast territories including Ukraine, Belarus, and the Baltic states. The treaty ended Russia's involvement in World War I but caused significant territorial losses and internal opposition.

Lenin introduced the NEP, allowing limited private enterprise and market mechanisms to revive the war-torn Soviet economy. The policy replaced War Communism, permitting small-scale capitalism while the state retained control of major industries.

Lenin oversaw the creation of the Union of Soviet Socialist Republics (USSR), a federation of Soviet republics. The new state consolidated Bolshevik control over much of the former Russian Empire and became a model for communist states worldwide.
