A Marxist, Vladimir Lenin founded Leninism, a type of communist doctrine. Lenin's Bolshevik administration initially shared power with the Left Socialist Revolutionaries, elected soviets, and a multi-party Constituent Assembly, yet by 1918, power had been consolidated in the new Communist Party. His slogan was "peace, bread, and land," and he garnered the support of Russian proletariat and factory workers by promising and preaching the communist principles.
