Bolshevism (from Bolshevik) is a revolutionary socialist current of Soviet Marxist–Leninist political thought and political regime associated with the formation of a rigidly centralized, cohesive and disciplined party of social revolution, focused on overthrowing the existing capitalist state system, seizing power and establishing the "dictatorship of the proletariat". In October 1917, the Bolshevik faction organized an armed uprising against the Provisional Government, formed by other (including socialist) parties and seized power (see the October Revolution).
