Half a century ago, the Greek academic Era Vranoussi presented Balkan and Byzantine studies with a new theory. She argued that the people named Albanoi in Michael Attaleiates’ History were not Balkan Albanians, but rather Normans in southern Italy. A debate ensued with French Byzantinist Alain Ducellier that was never resolved. More recently, some notable scholars have begun to incorporate Vranoussi's hypothesis into their work. This article re-examines Vranoussi's arguments and concludes that the evidence favours the traditional reading of Albanoi as Balkan Albanians over the interpretation of this ethnonym as an obscure reference to Norman mercenaries in territories south of Rome.
