The Sclaveni (in Latin) or (various forms in Greek) were early Slavic tribes that raided, invaded and settled the Balkans in the Early Middle Ages and eventually became 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 general catch-all term until the emergence of separate tribal names by the 10th century. Early Slavs The Sclaveni had similar if not identical customs and culture as the Antes. They were carefully described by chroniclers such as Procopius and Maurice, whose works contribute greatly to our understanding of these two Early Slavic peoples. Maurice writes that the Slavs were very hospitable people, tribes that mistreated guests were attacked for their dishonour. Prisoners were not kept forever and after a certain period of time, captives were allowed to be let loose or to join the community. Settlements were built in hard to reach forests, lakes and marshes as they were hard to attack, with exits in many directions for escape. They farmed many crops, especially millet, but also had much livestock of many sorts. Maurice praises their toleration of discomfort when necessary, and the loyalty of married women to their husbands. The Antes and Sclaveni were independent, refusing to be governed or enslaved. They lived under democracy, with all matters being referred to the people. The religion of the Sclaveni, like other Slavic tribes and peoples was Slavic paganism. The Antes and Sclaveni were skilled warriors, especially in guerrilla warfare, taking advantage of terrain. They preferred to fight in dense woodland instead of pitch battle, although field battles and sieges were also recorded.
