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.
Sloboda Ukraine
The name derives from the term "sloboda" for a colonial settlement free of tax obligations, and the word "ukraine" in its original sense of "borderland". The etymology of the word Ukraine is seen this way among Russian, Ukrainian and Western historians such as Orest Subtelny, Paul Magocsi, Omeljan Pritsak, Mykhailo Hrushevskyi, Ivan Ohiyenko, Petro Tolochko and others. It's supported by the Encyclopedia of Ukraine and the Etymological dictionary of the Ukrainian language. In Russia, the name "Ukraine" (Russian: "Ukraina") is perceived as a calque of "okraina", meaning a frontier ("krai"), thus "Sloboda Ukraine" is known as a "free-settled frontier". In Ukraine, the region is accepted as a free settled region, part of the whole Ukraine.
