The main figure in the Russian October Revolution of 1917 was Vladimir Lenin. He was a leading revolutionary and a prominent member of the Bolshevik Party, which advocated for a socialist government. Lenin returned to Russia from exile during the turmoil of the revolutions and played a crucial role in orchestrating the Bolsheviks’ seizure of power from the provisional government. His leadership marked the beginning of a new era, as the Bolsheviks aimed to establish a communist state, ultimately leading to the formation of the Soviet Union. Lenin's policies and ideology profoundly influenced global communism.
