The South Slavs are a subgroup of Slavic peoples who speak the South Slavic languages. They inhabit a contiguous region in the Balkan Peninsula and the eastern Alps, and in the modern era are geographically separated from the body of West Slavic and East Slavic people by the Romanians, Hungarians, and Austrians in between. The South Slavs today include the nations of Bosniaks, Bulgarians, Croats, Macedonians, Montenegrins, Serbs and Slovenes. They are the main population of the Eastern and Southeastern European countries of Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, North Macedonia, Serbia and Slovenia.
