Soviet Union

The Union of Soviet Socialist Republics (Союз Советских Социалистических Республик, Soyuz Sovetskikh Sotsialisticheskikh Respublik), also known as the Soviet Union (Советский Союз, Sovietskiy Soyuz) and USSR (СССР, SSSR) is a socialist state in Eurasia.

The socialist state on territory of former Russian Empire was created when Vladimir Lenin and the Communist Party overthrew the Provisional Government of Russia during the events of the October Revolution in November 7, 1917. The creation of the USSR as a de-jure federal union of Soviet republic, including Russia, Ukraine, Belorussia and now defunct Transcaucasia, was proclaimed in 1922 with the Treaty on the Creation of the USSR. Originally established as an one-party state, the Soviet Union went through democratic reforms into a political system similar to those of Union of American Socialist Republics.

The country is a member of the Third Communist International and one of its leading members, alongside with the UASR. USSR is one of the world's superpowers and obtains one of the most strongest economics, numerous armies and widest nuclear arsenals.
