Slavs are the largest ethno-linguistic group in Europe. Present-day Slavic people are classified into East Slavs (chiefly Belarusians, Russians, Rusyns, and Ukrainians), West Slavs (chiefly Czechs, Kashubs, Moravians, Poles, Silesians, Slovaks and Sorbs), and South Slavs (chiefly Bosniaks, Bulgarians, Croats, Macedonians, Gorani, Pomaks, Montenegrins, Serbs and Slovenes).
Post-Soviet transition in Ukraine
Between 1990 and 1991, several republics of the Soviet Union proclaimed their state sovereignty and then announced their independence. On July 16, 1990, the Ukrainian SSR's parliament issued its 12th legislation proclaiming the sovereignty of Ukraine's territory and the country eventually declared its independence on August 24, 1991. The declaration was then confirmed by the results of the referendum on December 1 later that year, where 90,3 % of voters were in favor of independence. The same day, Leonid Kravchuk, head of the Supreme Council of Ukraine, was elected as the country's first president. Following his election, an economic then political crisis developed and Kravchuk organized another presidential election as a response.
