Ukrainian Soviet Socialist Republic
The Ukrainian Soviet Socialist Republic (Ukrainian SSR or UkrSSR or UkSSR; , УРСР ; , УССР ; see "Name" section below), also known as the Soviet Ukraine, was one of the constituent republics of the Soviet Union from the Union's inception in 1922 to its breakup in 1991. The republic was governed by the Communist Party of Ukraine as a unitary one-party socialist soviet republic.
Republics of the Soviet Union
All of the former Republics of the Union are now independent countries, with ten of them (all except the Baltic states, Georgia and Ukraine) being very loosely organized under the heading of the Commonwealth of Independent States. However, most of the international community did not consider the Baltic countries (Lithuania, Latvia, and Estonia) to have legitimately been part of the USSR. The Baltic states assert that their incorporation into the Soviet Union in 1940 (as the Lithuanian, Latvian, and Estonian SSRs) under the provisions of the 1939 Molotov–Ribbentrop Pact was illegal, and that they therefore remained independent countries under Soviet occupation. Their position is supported by the European Union, the European Court of Human Rights, the United Nations Human Rights Council and the United States. In contrast, the Russian government and state officials maintain that the Soviet annexation of the Baltic states was legitimate.. Constitutionally, the Soviet Union was a federation. In accordance with provisions present in the Constitution (versions adopted in 1924, 1936 and 1977), each republic retained the right to secede from the USSR. Throughout the Cold War, this right was widely considered to be meaningless; however, the corresponding Article 72 of the 1977 Constitution was used in December 1991 to effectively dissolve the Soviet Union, when Russia, Ukraine, and Belarus seceded from the Union.
