The Russian Revolution is a major event that led to the end of the Tsarist autocracy, in 1917, and to the creation of the USSR in 1922. After the first revolution, which took place in February, in Petrograd (now St. Petersburg), the Tsar Nicholas II abdicated, and the power was seized by the Russian Provisional Government. After a period of trouble, the Bolsheviks, led by Vladimir Lenin, overthrew the provisional government and appointed themselves as leaders of the country. This was the October Revolution, also known as 'Red October.' The new power signed a treaty with Germany to end Russia's involvement in World War I, but a civil war erupted between 'the Whites,' anti-socialist parties, and 'The Reds,' the Bolsheviks, who eventually won and founded a new state that would rule Russia and a large part of the Eurasian continent for about 70 years.
