The document provides background information on the Russian Revolution through a vocabulary list and sections on pre-revolutionary Russia, the reign of Czar Nicholas II, World War I and the rise of the Bolsheviks. Key events summarized are the 1905 revolution in response to Bloody Sunday and the October Manifesto, World War I which weakened Russia and led to the March Revolution of 1917 overthrowing the Czar, and the Bolsheviks seizing power in November 1917 by promising to withdraw from WWI and preventing the Czar's return. A civil war followed between the Bolsheviks and opposing White Army which the Bolsheviks eventually won, allowing Lenin and the USSR to be established.
