Bolshevism
Bolshevism (derived from Bolshevik) is a revolutionary socialist Soviet Leninist, and later Marxist–Leninist, current of political thought and political regime that is associated with the formation of a rigidly centralized, cohesive and disciplined party of social revolution, and is focused on overthrowing the existing capitalist state system, seizing power and establishing the "dictatorship of the proletariat". Bolshevism originated at the beginning of the 20th century in the Russian Empire, and was associated with the activities of the Bolshevik faction within the Russian Social Democratic Labour Party led by Vladimir Lenin, Bolshevism's main theorist.
