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).
List of Presidents of Ukraine
The modern Ukrainian presidency was formed when the Verkhovna Rada of the Ukrainian Soviet Socialist Republic passed a law on 5 July 1991 establishing the office of the "President of the Ukrainian Soviet Socialist Republic." Upon the proclamation of Ukrainian independence from the Soviet Union on 24 August 1991, the title was changed to the "President of Ukraine." The first election of the President of Ukraine was contested on 1 December 1991, which was won by Leonid Kravchuk.
