Ukrainian Soviet Socialist Republic
The Ukrainian Soviet Socialist Republic (Ukrainian SSR or UkrSSR or UkSSR; , УРСР ; , УССР ; see "Name" section below), also known as the Soviet Ukraine, was one of the constituent republics of the Soviet Union from the Union's inception in 1922 to its breakup in 1991. The republic was governed by the Communist Party of Ukraine as a unitary one-party socialist soviet republic.
Ukrainian–Soviet War
The end of the war saw the incorporation of most of the territories of Ukraine into the Ukrainian Soviet Socialist Republic which, on December 30, 1922, was one of the founding members of the Union of Soviet Socialist Republics (USSR). Parts of Western Ukraine fell into under the control of the Second Polish Republic, as laid out in the Peace of Riga. The UNR government, led by Symon Petlura, was forced into exile. For the next few years the Ukrainian nationalists would continue to try to wage a partisan guerrilla war on the Soviets. They were aided by Polish intelligence (see Prometheism); however they were not successful. The last active Ukrainian movements would be mostly eradicated during the Holodomor. Further, the relative lack of Polish support for the Ukrainian cause would cause a growing resentment on the part of the Ukrainian minority in Poland towards the Polish interwar state.
