The Russian Revolution is the series of revolutions in Russia in 1917, which led to the creation of the Soviet Union. March 1917 was the first series of revolutions. The second revolutions started in October and over thru the Russian Government, Czar Nicholas, was removed and replaced with a Bolshevik (Communist) government .
Russia's small, educated classes, those exposed to foreign ideas, produced its revolutionaries, not the two most oppressed groups; the peasants and workers. After many years of failure, the revolutionaries found a new theory based on Karl Marx's ideas about socialism. Social Democrats, Russian Marxists, set up a national party, and then separated into the Mensheviks and the Bolsheviks. The Mensheviks believed socialist should copy socialists partied in Western Europe, while the Bolsheviks followed the tradition and believed in a tight dictatorial group that would take charge of the revolution and tell the proletariat what to do. They were led by Vladimir Ulyanov, who would later become famous under his political alias of Lenin.
