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).
Kiev culture
The Kyiv culture is an archaeological culture dating from about the 3rd to 5th centuries, named after Kyiv, the capital of Ukraine. It is widely considered to be the first identifiable Slavic archaeological culture. It was contemporaneous to (and located mostly just to the north of) the Chernyakhov culture.
