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.

In 1940, the Soviets annexed Bessarabia and northern Bukovina. The Ukrainian SSR incorporated the northern and southern districts of Bessarabia, northern Bukovina, and the Hertsa region. But it ceded the western part of the Moldavian Autonomous Soviet Socialist Republic to the newly created Moldavian Soviet Socialist Republic. These territorial gains of the USSR were internationally recognized by the Paris peace treaties of 1947.
German armies invaded the Soviet Union on 22 June 1941, initiating nearly four years of total war. The Axis initially advanced against desperate but unsuccessful efforts of the Red Army. In the encirclement battle of Kiev, the city was acclaimed as a "Hero City", because of its fierce resistance. More than 600,000 Soviet soldiers (or one-quarter of the Soviet Western Front) were killed or taken captive there, with many suffering severe mistreatment.
