(Βάραγγοι/Bárangoi). Scandinavians who from about the early 10th cent. AD arrived in Byzantium by way of the territory of the Kievan Rus (hence also often described as Ῥώς/Rṓs or Tauroscythae), from the 11th cent. also Anglo-Saxons who served in the Byzantine army (in which they were considered particularly trustworthy), but primarily in the Imperial Guard. Their characteristic weapon was the battle-axe, which earned them the nickname 'axe-bearers' (πελεκυφόροι/pelekyphóroi).
