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).
South Slavs
The Proto-Slavic homeland is the area of Slavic settlement in Central and Eastern Europe during the first millennium AD, with its precise location debated by archaeologists, ethnographers and historians. None of the proposed homelands reaches the Volga River in the east, over the Dinaric Alps in the southwest or the Balkan Mountains in the south, or past Bohemia in the west. Traditionally, scholars put it in the marshes of Ukraine, alternatively between the Bug and the Dnieper, however, according to F. Curta, the homeland of the southern Slavs mentioned by 6th-century writers was just north of the Lower Danube. Little is known about the Slavs before the 5th century, when they began spreading in all directions.
