The Bolsheviks: introduction by Grok 4.5 Fast Mode
**The Bolsheviks were a radical Marxist faction of the Russian Social-Democratic Workers’ Party (RSDLP), led by Vladimir Lenin, that seized power in Russia in the October Revolution of 1917 and established the world’s first communist state, which became the Soviet Union.**
The name comes from the Russian *bolshinstvo* (“majority”). It originated at the RSDLP’s Second Congress in 1903 (held in Brussels and London). Lenin’s supporters temporarily secured majorities on key votes—particularly favoring a restricted party of professional revolutionaries under centralized discipline (later called democratic centralism)—and adopted the label Bolsheviks. Their opponents, led by Julius Martov and favoring a broader membership open to sympathizers, were dubbed Mensheviks (“minority”), even though the Mensheviks often held greater influence in the years that followed. The factions intermittently cooperated but grew further apart; a more definitive split occurred around 1912.
Ideologically, the Bolsheviks were Marxists who adapted the theory to Russian conditions. Classical Marxism expected socialist revolution after a prolonged capitalist/bourgeois stage in advanced industrial societies. Lenin and the Bolsheviks argued that Russia’s weakly developed bourgeoisie, combined with the international crisis of imperialism and war, made an immediate transition to a “dictatorship of the proletariat” possible, guided by a disciplined vanguard party of professional revolutionaries rather than spontaneous mass action alone. They emphasized class struggle, the need to smash the existing state, and the eventual withering away of the state under full communism. In practice this produced a highly hierarchical, conspiratorial organization suited to underground work under Tsarist repression.
The Bolsheviks played a limited role in the 1905 Revolution. After the February Revolution of 1917 overthrew the Tsar and installed a Provisional Government, the Bolsheviks remained a minority. Lenin returned from exile in April 1917 (facilitated by Germany) and issued the April Theses, rejecting cooperation with the Provisional Government, demanding “all power to the soviets” (workers’, soldiers’, and peasants’ councils), immediate peace, and land redistribution. Support grew among urban workers, soldiers, and sailors amid wartime collapse, food shortages, and the Provisional Government’s continued involvement in World War I. By autumn 1917 the Bolsheviks held majorities in the Petrograd and Moscow Soviets.
On 25–26 October 1917 (7–8 November New Style), Bolshevik-led forces (including Red Guards organized with key involvement by Leon Trotsky) seized key points in Petrograd and overthrew the Provisional Government in a relatively low-casualty insurrection often described as a coup. The Second All-Russian Congress of Soviets, then sitting, endorsed the transfer of power. The Bolsheviks formed a new government (Council of People’s Commissars) under Lenin. They issued decrees on peace and land, withdrew from World War I via the Treaty of Brest-Litovsk (1918), and nationalized industry. They shared power briefly with Left Socialist Revolutionaries but soon suppressed rival parties, closed opposition presses, and dissolved the Constituent Assembly (elected in late 1917, in which they did not hold a majority) after it refused to recognize Soviet power exclusively.
In March 1918 the party renamed itself the Russian Communist Party (Bolsheviks). It prevailed in the ensuing Russian Civil War (roughly 1917–1922) against White forces, other socialists, nationalists, and foreign interventions, employing the Red Army, the Cheka secret police, and policies of War Communism (nationalization, grain requisitioning, labor conscription). The Union of Soviet Socialist Republics was formed in 1922. The name “Bolshevik” remained in official party titles until 1952, when it became simply the Communist Party of the Soviet Union.
In short, the Bolsheviks began as one faction in a divided Marxist party, developed a distinctive theory and organizational model under Lenin, exploited the dual power situation and wartime crisis of 1917 to take state power, and then consolidated a one-party regime that ruled the Soviet state for decades. Their success rested on disciplined organization, opportunistic slogans that matched popular demands for peace, land, and soviet power, and the weakness of their opponents—not on holding a pre-existing popular majority across the empire.
You must understand, the leading Bolsheviks who took over Russia were not Russians. They hated Russians. They hated Christians.
Driven by ethnic hatred they tortured and slaughtered millions of Russians without a shred of human remorse. It cannot be overstated. Bolshevism… pic.twitter.com/qWp99HgSpR
