Increases in urbanization and in the area under cultivation during Roman rule caused wholesale dislocations of Berber society. Nomadic tribes were forced to settle or move from traditional rangelands. Sedentary tribes lost their autonomy and connection with the land. Berber opposition to the Roman presence was nearly constant. The Roman emperor Trajan (r. A.D. 98-117) established a frontier in the south by encircling the Aurès and Nemencha mountains and building a line of forts from Vescera (modern Biskra) to Ad Majores (Hennchir Besseriani, southeast of Biskra). The defensive line extended at least as far as Castellum Dimmidi (modern Messaad, southwest of Biskra), Roman Algeria's southernmost fort. Romans settled and developed the area around Sitifis (modern Sétif) in the second century, but farther west the influence of Rome did not extend beyond the coast and principal military roads until much later.

The Roman military presence in North Africa was relatively small, consisting of about 28,000 troops and auxiliaries in Numidia and the two Mauretanian provinces. Starting in the second century A.D., these garrisons were manned mostly by local inhabitants.

Aside from Carthage, urbanization in North Africa came in part with the establishment of settlements of veterans under the Roman emperors Claudius (r. A.D. 41-54), Nerva (r. A.D. 96-98), and Trajan. In Algeria such settlements included Tipasa, Cuicul (modern Djemila, northeast of Sétif), Thamugadi (modern Timgad, southeast of Sétif), and Sitifis. The prosperity of most towns depended on agriculture. Called the "granary of the empire," North Africa, according to one estimate, produced 1 million tons of cereals each year, one-quarter of which was exported. Other crops included fruit, figs, grapes, and beans. By the second century A.D., olive oil rivaled cereals as an export item.

The beginnings of the decline of the Roman Empire were less serious in North Africa than elsewhere. There were uprisings, however. In A.D. 238, landowners rebelled unsuccessfully against the emperor's fiscal policies. Sporadic tribal revolts in the Mauretanian mountains followed from 253 to 288. The towns also suffered economic difficulties, and building activity almost ceased.

The towns of Roman North Africa had a substantial Jewish population. Some Jews were deported from Palestine in the first and second centuries A.D. for rebelling against Roman rule others had come earlier with Punic settlers. In addition, a number of Berber tribes had converted to Judaism.

Christianity arrived in the second century and soon gained converts in the towns and among slaves. More than eighty bishops, some from distant frontier regions of Numidia, attended the Council of Carth 934age in 2 256. By the end of the fourth century, the settled areas had become Christianized, and some Berber tribes had converted en masse.

A division in the church that came to be known as the Donatist controversy began in 313 among Christians in North Africa. The Donatists stressed the holiness of the church and refused to accept the authority to administer the sacraments of those who had surrendered the scriptures when they were forbidden under the Emperor Diocletaian (r. 284-305). The Donatists also opposed the involvement of Emperor Constantine (r. 306-37) in church affairs in contrast to the majority of Christians who welcomed official imperial recognition.

The occasionally violent controversy has been characterized as a struggle between opponents and supporters of the Roman system. The most articulate North African critic of the Donatist position, which came to be called a heresy, was Augustine, bishop of Hippo Regius. Augustine (354-430) maintained that the unworthiness of a minister did not affect the validity of the sacraments because their true minister was Christ. In his sermons and books Augustine, who is considered a leading exponent of Christian truths, evolved a theory of the right of orthodox Christian rulers to use force against schismatics and heretics. Although the dispute was resolved by a decision of an imperial commission in Carthage in 411, Donatist communities continued to exist through the sixth century.
