Ukrainian Soviet Socialist Republic
Eventually, after the creation of the Communist Party (Bolshevik) of Ukraine in Moscow, a third Ukrainian Soviet government was formed on 21 December 1919 that initiated new hostilities against Ukrainian nationalists as they lost their military support from the defeated Central Powers. Eventually, the Red Army ended up controlling much of the Ukrainian territory after the Polish-Soviet Peace of Riga. On 30 December 1922, along with the Russian, Byelorussian, and Transcaucasian republics, the Ukrainian SSR was one of the founding members of the Union of Soviet Socialist Republics (USSR).
Ukraine and the United Nations
Ukraine signed the Charter of the United Nations as the Ukrainian Soviet Socialist Republic on 26 June 1945 and came into force on 24 October 1945. Ukraine was among the first countries that signed the United Nations Charter, becoming a founding member of the United Nations among 51 countries. This provided the Soviet Union (a permanent Security Council member with veto powers) with another vote in the General Assembly. The latter aspect of the 1944 clauses, however, was never fulfilled and the republic's defense matters were managed by the Soviet Armed Forces and the Defense Ministry.
