Slavs

The Slavs or Slavic people are groups of people who speak Slavic languages. Slavs are geographically distributed throughout the northern parts of Eurasia; they predominantly inhabit Central Europe, Eastern Europe, Southeastern Europe, and Northern Asia, though there is a large Slavic minority scattered across the Baltic states and Central Asia, and a substantial Slavic diaspora in the Americas, Western Europe, and Northern Europe.

Early Slavs lived during the Migration Period and the Early Middle Ages (approximately from the 5th to the 10th century AD), and came to control large parts of Central, Eastern, and Southeast Europe between the sixth and seventh centuries. Beginning in the 7th century, they were gradually Christianized. By the 12th century, they formed the core population of a number of medieval Christian states: East Slavs in the Kievan Rus', South Slavs in the Bulgarian Empire, the Principality of Serbia, the Duchy of Croatia and the Banate of Bosnia, and West Slavs in the Principality of Nitra, Great Moravia, the Duchy of Bohemia, and the Kingdom of Poland.

Beginning in the mid-19th century, a pan-Slavic movement has emphasized the common heritage and unity of all the Slavic peoples. The main focus of the movement was in the Balkans, whereas the Russian Empire was opposed to it.

The Slavic languages belong to the Balto-Slavic branch of the Indo-European language family. Present-day Slavs are classified into three groups:

Though the majority of Slavs are Christians, some groups, such as the Bosniaks, mostly identify as Muslims. Modern Slavic nations and ethnic groups are considerably diverse, both genetically and culturally, and relations between them may range from "ethnic solidarity to mutual feelings of hostility" — even within the individual groups.

The oldest mention of the Slavic ethnonym is from the 6th century AD, when Procopius, writing in Byzantine Greek, used various forms such as Sklaboi (Σκλάβοι), Sklabēnoi (Σκλαβηνοί), Sklauenoi (Σκλαυηνοί), Sthlabenoi (Σθλαβηνοί), or Sklabinoi (Σκλαβῖνοι), and his contemporary Jordanes refers to the Sclaveni in Latin. The oldest documents written in Old Church Slavonic, dating from the 9th century, attest the autonym as Slověne (Словѣне). Those forms point back to a Slavic autonym, which can be reconstructed in Proto-Slavic as *Slověninъ, plural Slověne.

The reconstructed autonym *Slověninъ is usually considered a derivation from slovo ("word"), originally denoting "people who speak (the same language)", meaning "people who understand one another", in contrast to the Slavic word denoting "German people", namely *němьcь, meaning "silent, mute people" (from Slavic *němъ "mute, mumbling"). The word slovo ("word") and the related slava ("glory, fame") and sluh ("hearing") originate from the Proto-Indo-European root *ḱlew- ("be spoken of, glory"), cognate with Ancient Greek κλέος (kléos "fame"), as in the name Pericles, Latin clueō ("be called"), and English loud.

In medieval and early modern sources written in Latin, Slavs are most commonly referred to as Sclaveni or the shortened version Sclavi.
