There is disagreement among the chroniclers over the origins of the raiders who attacked Rome, although most sources describe them as Saracens. According to the "Liber Pontificalis" and the "Chronicle of Monte Cassino", the raiders were Saracens from Africa who raided Corsica before attacking Rome. The "Annals of Fulda", on the other hand, describe the raiders as Moors (), which generally indicated Muslims from al-Andalus (Spain) or the Maghreb, as opposed to Ifriqiya. The author of the "Annals of Xanten" was unsure: he called the raiders "either Moors or else Saracens". It is possible that the annals, which are from north of the Alps, were using "Moors" as a synonym for "Saracens". No Italian source describes the raiders of 846 as Moors.
