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).
North Slavs
North Slavic peoples today include the Belarusians, Czechs, Kashubians, Poles, Silesians, Rusyns, Russians, Slovaks, Sorbs, and Ukrainians. They inhabit a contiguous area in Central and Eastern Europe stretching from the north of the Baltic Sea to the Sudetes and the Carpathian Mountains in the south (historically also across the Eastern Alps into the Apennine peninsula and the Balkan peninsula); from the west in the Czech Republic to the east in the Russian Federation. There is also a significant share of North Slavic population in North Asia (Eastern Russia), and significant diaspora groups throughout the rest of the world.
