29 Jul Soviet Union
As a state, The Union of Soviet Socialist Republics abbreviated to the Soviet Union or USSR existed between 1922 and 1991. It had its roots in the Bolshevik Revolution of 1917 that deposed and executed Tsar Nicolas II, the last in the three-hundred-year-old Romanov dynasty.
The stated purpose of the Soviet Union was to build socialism and, subsequently, communism. It was a single-party state ruled by the Communist Party.
The Soviet Union was comprised of fifteen autonomous republics that became independent states after the Soviet Union dissolved.
Through its history, the Soviet Union relied on a planned economy where production and distribution of goods were regulated and controlled by the federal government, domestic prices fixed by the federal government, and education and healthcare government-funded.
