The main outcome of the Russian Revolution, which comprised events in February and October 1917, was the establishment of a communist government. Following the abdication of Tsar Nicholas II, a provisional government was set up but struggled with war and economic turmoil. Discontent led to the rise of the Bolsheviks, led by Vladimir Lenin, who advocated for radical change. The October Revolution resulted in the Bolsheviks seizing power and subsequently withdrawing Russia from World War I. This shift culminated in the creation of the Soviet Union in 1922, fundamentally altering Russian society and politics while inspiring global revolutionary movements throughout the 20th century.
