The extension of the Roman control into the African desert is known by the construction of the limes system in what are modern Libya, Tunisia and Algeria under the emperor Septimius Severus AD 193-211. The limes system is marked by the construction of some forts deep into the desert, these forts were not defensive in the first place or- as some historians imaged it- as a separation limit that divided the two different societies, contra this view, the limes was contact point between two different societies from many aspects, It helped bridge the width between them, by giving the indigenous communities the culture and style of the Roman life. In time the limes was moved whenever there was a possibility for extending it. The Severan constructions in Numidia included some forts as well as custom stations to control over the transhumance out and into the Limes Zone. Most important was the raising Numidia to the dignity of a province. Septimius Severus is considered the real founder of the limes Tripolitanus, he reached with the constructions the heart of the African desert. We believe that the Romanization of Africa was a target and result at the same time of the Limes constructions ukryj opis
