Slavs are the largest European ethnolinguistic group. They speak the various Slavic languages, belonging to the larger Balto-Slavic branch of the Indo-European languages. Slavs are geographically distributed throughout northern Eurasia, mainly inhabiting Central and Eastern Europe, and the Balkans to the west; and Siberia to the east. A large Slavic minority is also scattered across the Baltic states and Central Asia, while a substantial Slavic diaspora is found throughout the Americas, as a result of immigration.

Present-day Slavs are classified into East Slavs (chiefly Belarusians, Russians, Rusyns, and Ukrainians), West Slavs (chiefly Czechs, Kashubians, Poles, Slovaks and Sorbs) and South Slavs (chiefly Bosniaks, Bulgarians, Croats, Macedonians, Montenegrins, Serbs and Slovenes).
