The main outcome of the Russian Revolution in 1917 was the overthrow of the Tsarist autocracy and the establishment of a communist government led by the Bolsheviks. The revolution consisted of two significant phases: the February Revolution, which forced Tsar Nicholas II to abdicate, and the October Revolution, which saw the Bolsheviks, led by Vladimir Lenin, seize power. This transformation led to the withdrawal of Russia from World War I and significant political, economic, and social changes, including the nationalization of industry and land redistribution. The revolution not only reshaped Russia but also contributed to the worldwide proliferation of communist ideology.
