The Soviet Union,[t] officially the Union of Soviet Socialist Republics[u] (USSR),[v] was a transcontinental country that spanned much of Eurasia from 1922 to 1991. The country was a successor state to the Russian Empire; it was nominally a federal union of fifteen national republics, the largest and most populous of which was the Russian SFSR,[w] but in practice both its government and its economy were highly centralized until its final years. As a one-party state governed by the Communist Party of the Soviet Union, it was a flagship communist state.
