In the Roman Empire, the dediticii were one of the three classes of libertini. The dediticii existed as a class of persons who were neither slaves, nor Roman citizens (cives), nor Latini (that is, those holding Latin rights), at least as late as the time of Ulpian. Dediticii who were former slaves were perceived as a threat to society, regardless of whether their master's punishments had been justified, and if they came within a hundred miles of Rome, they were subject to reenslavement.
