The code entrenches a clear stratification of Gothic and Gallo-Roman society. There is the class of lords, who are called either domini or patroni depending on whether or not they lord it over slaves or freemen. And there are two classes of freemen who have lords above them: the buccellarii and the saiones. The Code was in fact the first legal recognition of the buccellariatus, an office which the Roman Emperors were trying to ban. The buccellarii were a knightly class, they could change lords, but they had to return all the landed benefices they had received from their former lord.
