The Soviet Union (Russian: Сове́тский Сою́з, tr. Sovetskiy Soyuz [sɐ'vʲetskʲɪj sɐˈjʉs]), officially the Union of Soviet Socialist Republics (USSR; Сою́з Сове́тских Социалисти́ческих Респу́блик (СССР), Soyuz Sovetskikh Sotsialisticheskikh Respublik (SSSR) [sɐˈjus sɐˈvʲɛtskʲɪx sətsɨəlʲɪsˈtʲitɕɪskʲɪx rʲɪˈspublʲɪk]), also known unofficially as Russia (Russian: Росси́я, tr. Rossiya; IPA: [rɐˈsʲijə]), was a socialist state in Eurasia that existed from 1922 to 1991. Nominally a union of multiple equal national Soviet republics, its government and economy were highly centralized in a state that was unitary in most respects. The country was a one-party federation, governed by the Communist Party with Moscow as its capital.
The Soviet Union had its roots in the October Revolution of 1917, when the Bolsheviks, led by Vladimir Lenin, overthrew the Russian Provisional Government which had replaced Tsar Nicholas II. In 1922, the Soviet Union was formed with the unification of the Russian, Transcaucasian, Ukrainian, and Byelorussian republics. Following Lenin's death in 1924 and a brief power struggle, Joseph Stalin came to power in the mid-1920s. Stalin committed the state's ideology to Marxism–Leninism (which he created), and initiated a centrally planned economy. As a result, the country underwent a period of rapid industrialization and collectivization. Political paranoia was also fomented around Stalin, and the Great Purge was carried out to remove his opponents from the Communist Party through arbitrary arrests and persecutions of many people.
