The document provides background information on factors that led to the Communist revolution in Russia in 1917. These included the weakness of Tsar Nicholas II's autocratic rule; widespread discontent among peasants, workers, and opposition groups like Communists; and Russian failures in World War I. The February Revolution of 1917 overthrew the Tsar, but the Provisional Government that replaced him was weak. In October 1917, Lenin and the Bolsheviks seized power in the October Revolution, establishing Soviet rule.
