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).
1990 Ukrainian Supreme Soviet election
The parliamentary convocation that convened after the 1990 election declared the independence of Ukraine from the Soviet Union on August 24, 1991. Later on, an amendment to the official number of parliamentary convocations recognized this 12th Convocation of the Parliament of the Ukrainian SSR as the first Parliament of Ukraine of the 1st Convocation.
