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).
Slavic paganism
The Christianisation of the Slavic peoples was, however, a slow and—in many cases—superficial phenomenon, especially in what is today Russia. Christianisation was vigorous in western and central parts of what is today Ukraine, as they were closer to the capital Kiev, but even there, popular resistance led by "volkhv"s, pagan priests or shamans, recurred periodically for centuries. Even though the Byzantine Christianization firstly has slowed down the Eastern Slavic traditions in Rus', it has preserved the Slavic traditions in the long term. While local Slavic figures and myths, such as Baba Roga in Croatia were forgotten, Slavic culture continued to exist and even flourish in the Eastern Slavic countries. In the case of a Christian Latinization of the Eastern Slavic countries, this may not have been the case.
