The people who conquered Bari were people from the fucking tiny Roman province of ARabia by the ancient ROman definition, and it makes sense to apply it to a time 400 years after the Roman Empire fell, and not "Saracens" in the general medieval form of the word which came to mean all practicioners of Islam including berbers, turks, and arabs. This makes a lot of sense, and isnt a really retarded line of arguement.
