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