Leninism is the political theory for the organisation of a revolutionary vanguard party and the achievement of a dictatorship of the proletariat, as political prelude to the establishment of socialism.[1] Developed by and named for the Russian revolutionary Lenin, Leninism comprises socialist political and economic theories, developed from Marxism, and Lenin's interpretations of Marxist theories, for practical application to the socio-political conditions of the Russian Empire of the early 20th century.
