The Bolshevik Revolution, also known as the October Revolution, took place in Russia in 1917. It resulted in the overthrow of the Provisional Government, established by the February Revolution earlier that same year. The Bolsheviks, led by Vladimir Lenin, aimed to implement a socialist government and withdrew Russia from World War I. This revolution led to the establishment of the Soviet Union in 1922 and had a profound impact on global politics, ideology, and the spread of communism.
