Sclaveni

The Sclaveni (in Latin) or Sklabenoi (various forms in Greek) were early Slavic tribes that raided, invaded and settled in Southeastern Europe in the Early Middle Ages and eventually became one of the progenitors of modern South Slavs. They were mentioned by early Byzantine chroniclers as barbarians having appeared at the Byzantine borders along with the Antes (East Slavs), another Slavic group. The Sclaveni were differentiated from the Antes and Wends (West Slavs); however, they were described as kin. Eventually, most South Slavic tribes accepted Byzantine or Frankish suzerainty, and came under their cultural influences and Chalcedonian Christianity. The term was widely used as a general catch-all term until the emergence of separate tribal names by the 10th century.
