The people of the area were first identified as
Numidians by
Polybius around the 2nd century BC, although they were often referred to as the Nodidians. from
Cherchell, Algeria.
Louvre Museum Eastern Numidia was annexed in 46 BC to create a new Roman province,
Africa Nova.
Western Numidia was also annexed as part of the province
Africa Nova after the death of its last king,
Arabio, in 40 BC, and subsequently the province (except of
Western Numidia) was united with province
Africa Vetus by Emperor
Augustus in 25 BC, to create the new province
Africa Proconsularis. During the brief period (30–25 BC)
Juba II (son of
Juba I) ruled as a client king of Numidia on the territory of former province
Africa Nova. In AD 40, the western portion of Africa Proconsularis, including its legionary garrison, was placed under an imperial
legatus, and in effect became a separate province of Numidia, though the
legatus of Numidia remained nominally subordinate to the proconsul of Africa until AD 203.
Christianity spread there from the 2nd century onwards. During the second century, the province was
Christianized, but in the fourth century, it adhered to the
Donatist heresy, despite giving rise to men of Orthodox faith as illustrious as
Saint Augustine, bishop of
Hippo Regius (present
Annaba). After 193, under
Septimius Severus, Numidia was officially detached from the province of Africa and constituted a province in its own right, governed by an imperial
legatus pro praetore. Under
Diocletian, it constituted a simple province in the
tetrarchic reorganization, then was divided in two:
Numidia Cirtensis, with capital at
Cirta, and
Numidia Militiana ("Military Numidia"), with capital at the legionary base of
Lambaesis. However, after decades, Emperor
Constantine the Great reunited the two provinces in a single one, administered from Cirta, which was now renamed
Constantina (modern
Constantine). In 428, the
Vandals began their incursions in the African provinces. They eventually managed to create the
Vandal Kingdom that lasted between 432 and 534, the year in which the Vandals fell and the African provinces was reincorporated into
(Eastern) Roman domain and formed the
Praetorian prefecture of Africa, half a century later the
Exarchate of Africa, by the reign of Maurice (r. 582–602). Between 696 and 708, the region was conquered again,
this time by the Arab Muslims (Umayyad), and became part of
Ifriqiya. == Major cities ==
