The Russian Revolution occurred from 8 March to 8 November 1917 when the Russian Empire was overthrown by Alexander Kerensky's liberal "Provisional Government", which was then ousted from power by Vladimir Lenin's Bolsheviks. The revolution abruptly ended World War I for the Russian Empire, whose king Nicholas II of Russia would be executed along with his family by the Bolsheviks. The revolution occurred in response to the poor leadership of Czar Nicholas, his oppression of ethnic and religious minorities in the country, and Russia's absolute monarchy. The State Duma, Russia's parliament, seized power in March 1917, and Kerensky established a social democratic government. However, the communist Bolsheviks ousted the provisional government from power in October 1917, and the Russian SFSR was founded to replace the Russian Empire. The capital was moved from Petrograd (St. Petersburg) to Moscow, and the revolution would lead to the Russian Civil War between the monarchist White Army and the communist Bolsheviks, eventually leading to the rise of the Soviet Union in 1922.
