Soviet Union

Soviet Union (officially Union of Soviet Socialist Republics, USSR) Former federal republic, successor to the Russian Empire and the world's first communist state. The Soviet Union formed on December 30, 1922 and, when dissolved on December 31, 1991, was the largest country in the world. The Bolshevik regime, led by Lenin, came to power in the Russian Revolution (1917). Lenin's government survived civil war (1918–22) and famine by instituting a centralized command economy. In 1921, the New Economic Policy (NEP) marked a return to a mixed economy. In 1922, the republics of Russia, Ukraine, Belorussia, and Transcaucasia signed a treaty of union. In 1923, a new constitution was adopted establishing the supremacy of the Communist Party of the Soviet Union (CPSU), and the Supreme Soviet as the highest legislative body. Lenin died in January 1924, and a power struggle ensued between Leon Trotsky and Joseph Stalin. Stalin emerged the victor, and Trotsky was expelled in 1927.
