The Russian Revolution In Pictures (21 pictures)

The Russian Revolution that led to the formation of the Soviet Union is a long story of relatively fast social change in a short amount of time. Because Russia was still using the Julian calendar at the time, they are known as the February and October Revolutions. Following the Bolshevik uprising in November, a four-year civil war would break out between the communist Red Army and the conglomeration of loosely affiliated anti-Bolsheviks, ending with the cementing of the Communist state and the formal founding of the USSR.
