Sclaveni raided and settled the western Balkans in the 6th and 7th century. The White Serbs are mentioned in De Administrando Imperio as having settled the Balkans during the reign of Byzantine Emperor Heraclius (r. 610–641), however, research does not support that the White Serbian tribe was part of this later migration (as held by historiography) rather than migrating with the rest of Early Slavs.
