Donatism was a Christian sect leading to a schism in the Church, in the region of the Church of Carthage, from the fourth to the sixth centuries. Donatists argued that Christian clergy must be faultless for their ministry to be effective and their prayers and sacraments to be valid. Donatism had its roots in the long-established Christian community of the Roman province Africa Proconsularis and Mauretania Tingitana, in the persecutions of Christians under Diocletian. Named after the Berber Christian bishop Donatus Magnus, Donatism flourished during the fourth and fifth centuries. Donatism mainly spread among the indigenous Berber population, and Donatists were able to blend Christianity with many of the Berber local customs.

The Archdiocese of Carthage, also known as the Church of Carthage, was a Latin Catholic diocese established in Carthage, Roman Empire, in the 2nd century. Agrippin was the first named bishop, around 230 AD. The temporal importance of the city of Carthage in the Roman Empire had previously been restored by Julius Caesar and Augustus. When Christianity became firmly established around the Roman province of Africa Proconsulare, Carthage became its natural ecclesiastical seat. Carthage subsequently exercised informal primacy as an archdiocese, being the most important center of Christianity in the whole of Roman Africa, corresponding to most of today's Mediterranean coast and inland of Northern Africa. As such, it enjoyed honorary title of patriarch as well as primate of Africa: Pope Leo I confirmed the primacy of the bishop of Carthage in 446: "Indeed, after the Roman Bishop, the leading Bishop and metropolitan for all Africa is the Bishop of Carthage."

Tertullian (c. 155–240), a theologian of part Berber descent, was instrumental in the development of trinitarian theology, and was the first to apply Latin language extensively in his theological writings. As such, Tertullian has been called "the father of Latin Christianity" and "the founder of Western theology."
