The revolution aimed at establishing a communist state in Russia is known as the Bolshevik Revolution, which occurred in October 1917. Led by figures like Vladimir Lenin and the Bolshevik party, the revolution overthrew the provisional government that had been set up after the February Revolution earlier that year. The Bolsheviks promised peace, land, and bread to the war-weary populace and sought to implement Marxist principles. This revolution led to the establishment of the Soviet Union, fundamentally transforming not only Russia but also inspiring leftist movements worldwide.
