The document summarizes key figures and events of the Russian Revolution:
Joseph Stalin gained control of the Soviet Union in 1929 and introduced the Five Year Plans to rapidly industrialize the nation. He collectivized agriculture which caused social distress. Vladimir Lenin led the Bolsheviks to power in 1917 and established the world's first socialist state, nationalizing banks and industry. The Bolsheviks split from the Menshevik faction and came to power during the October Revolution. Leon Trotsky was a leader within the Bolsheviks and founded the Red Army, but later opposed Stalin's rise to power and was assassinated in exile.
