Slavs
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).
History of Ukrainian nationality
The history of Ukrainian nationality can be traced back to the Kiev-based kingdom of Kievan Rus' () of the 9th to 12th centuries. It was the predecessor state to what would eventually become the Eastern Slavic nations of Belarus, Russia, and Ukraine. During this time, Eastern Orthodoxy, a defining feature of Ukrainian nationalism, was incorporated into everyday life.
