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.
History of Ukraine
The Second World War began in September 1939, when Hitler and Stalin invaded Poland, the Soviet Union taking most of Western Ukraine. Nazi Germany with its allies invaded the Soviet Union in 1941. Some Ukrainians initially regarded the Wehrmacht soldiers as liberators from Soviet rule, while others formed a partisan movement. Some elements of the Ukrainian nationalist underground formed a Ukrainian Insurgent Army that fought both Soviet forces and the Nazi. Others collaborated with the Germans. In Volhynia, Ukrainian fighters committed a massacre against up to 100,000 Polish civilians. Residual small groups of the UPA-partizans acted near the Polish and Soviet border as long as to the 1950s.
