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).
Nuclear weapons and Ukraine
On December 1, 1991, Ukraine, the second most powerful republic in the Soviet Union (USSR), voted overwhelmingly for independence, which ended any realistic chance of the Soviet Union staying together even on a limited scale. More than 90% of the electorate expressed their support for Ukraine's declaration of independence, and they elected the chairman of the parliament, Leonid Kravchuk as the first president of the country. At the meetings in Brest, Belarus on December 8, and in Alma Ata on December 21, the leaders of Belarus, Russia, and Ukraine formally dissolved the Soviet Union and formed the Commonwealth of Independent States (CIS).
