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).
Stefan Terlezki
When the Soviet Union collapsed in 1991, Terlezki became a critical supporter of newly independent Ukraine. He condemned the preservation of close ties with Russia, especially the leasing of military bases in Crimea and argued that more should be done to promote the Ukrainian language and to discourage the use of Russian. In 2003, he visited the European Parliament to press the case for eventual Ukrainian membership of the European Union.
