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 Ukraine
In 882, Kiev was conquered from the Khazars by the Varangian noble Oleg who started the long period of rule of the Rurikid princes. During this time, several Slavic tribes were native to Ukraine, including the Polans, the Drevlyans, the Severians, the Ulichs, the Tiverians, the White Croats and the Dulebes. Situated on lucrative trade routes, Kiev among the Polanians quickly prospered as the center of the powerful Slavic state of Kievan Rus.
