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).
Ukrainian Soviet Socialist Republic
After the ratification of the 1936 Soviet Constitution, the names of all Soviet republics were changed, transposing the second ("socialist") and third ("soviet" or "radianska" in Ukrainian) words. In accordance, on 5 December 1936, the 8th Extraordinary Congress Soviets in Soviet Union changed the name of the republic to the "Ukrainian Soviet Socialist Republic", which was ratified by the 14th Extraordinary Congress of Soviets in Ukrainian SSR on 31 January 1937.
