Belarus–Ukraine relations
Belarus–Ukraine relations (, "Byelaruska-ŭkrainskiya adnosiny", , "Ukrains'ko-Bilorus'ki vidnosyny", , "Belorussko-ukrainskiye otnosheniya") are foreign relations between Belarus and Ukraine. Both countries were successively ruled by the Polish-Lithuanian Commonwealth, the Second Polish Republic, and ultimately, the Russian Empire. Prior to the 1991 breakup, both countries were part of the Soviet Union as the Belarusian SSR and Ukrainian SSR when they were the founding members of the United Nations in 1945. Being Slavic nations, both Belarus and Ukraine share closely related cultures and are predominantly inhabited by the East Slavic ethnic groups of Belarusians and Ukrainians respectively, along with a few Russians. Today, the two countries share an 891–km border.
Ukrainian Soviet Socialist Republic
Following the failed August Coup in Moscow on 19–21 August 1991, the Supreme Soviet of Ukraine declared independence on 24 August 1991, which renamed the Ukrainian Soviet Socialist Republic to Ukraine. The result of the 1991 independence referendum held on 1 December 1991 proved to be a surprise. An overwhelming majority, 92.3%, voted for independence. The referendum carried in the majority of all oblasts. Notably, the Crimea, which had originally been a territory of the RSFSR until 1954, supported the referendum by a 54 percent majority. Over 80 percent of the population of Eastern Ukraine voted for independence. Ukraine's independence from the Soviet Union led to an almost immediate recognition from the international community. Ukraine's new-found independence was the first time in the 20th century that Ukrainian independence had not been attempted without either foreign intervention or civil war. In the 1991 Ukrainian presidential election 62 percent of Ukrainians voted for Leonid Kravchuk. The secession of the second most powerful republic in the Soviet Union ended any realistic chance of the Soviet Union staying together even on a limited scale. The Soviet Union formally dissolved three weeks after Ukraine's secession.
