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).

Under the influence of Mikhail Gorbachev's perestroika and glasnost years, the individual Soviet republics had strengthened their sense of national identity, which led to the Collapse of the Soviet Union in 1991. This concerned the three Baltic states and Western Ukraine, which were the last territories annexed into Soviet Union. These efforts were accompanied with attempts to restore the respective historical national symbols. In 1988, the Supreme Soviet of the Lithuanian SSR re-established Lithuania's historic coat of arms as the state symbol. The Parliaments of Latvia and Estonia soon followed.
