The North African province built on the former Numidian kingdom's core, garrisoned by Legio III Augusta at Lambaesis; it gained its own imperial legatus in AD 40 and grew administratively distinct from Africa Proconsularis through the 2nd century before formal detachment under Septimius Severus.
Formally split from Africa Proconsularis under Septimius Severus (officially detached after AD 193, legatus fully independent by 203); later divided by Diocletian into Numidia Cirtensis and Numidia Militiana, reunited by Constantine, then overrun by the Vandals from 428.
