The October Revolution in Russia, which occurred in 1917, served as a normalizing force for the Bolshevik regime by establishing a new social and political order based on Marxist principles. The Bolsheviks, led by Vladimir Lenin, overthrew the provisional government and instituted radical changes, including land redistribution and workers' control of factories. This revolution not only ended centuries of imperial rule but also initiated a civil war that solidified communist power. The October Revolution inspired numerous communist movements globally, reshaping the political landscape of the 20th century and establishing the Soviet Union as a formidable force on the world stage.
