The Law of Persons was concerned with the different types of status and legal rights enjoyed by persons. "The main distinction in the law of Persons", says Gaius, "is that all men are either free of slaves." Rights depended on one's status; hence the rights enjoyed by a slave, or a son in power, for example, differed substantially from those enjoyed by a paterfamilias.
