Sabaea: Sabaea, one of the most mountainous regions of Africa and the location of modern Ethiopia, formerly known as Abyssinia. Sabaea was also known as Seba and later as the Kingdom of Askum.
The Ethiopian Orthodox Church: Askum's official religion (Christianity) began about A.D. 300 when two Christian youths, Edesius and Frumentius, preached the gospel in King Ezana's court when they were taken to Ethipia as slaves.
Early Christianity in North Africa: Alexandria in Egypt. Cyrene in Libya, and Carthage in Tunisia became important and influential centers of Christianity.
Carthage was the city of the great early church fathers Tertullian and Cyprian, both of whom were martyred for the faith.
Alexandria was the home of the theologians Clement of Alexandria and Origen; Clement's hymn "Shperd of Tender Youth" is the oldest surviving Christian hymn.
The two greatest Norh African Chistians were: *Athanasius: The eloquent and impassioned spokesman for the deity of Christ. *Ausustine of Hippo: He championed the biblical emphasis of salvation by grace alone and later inspired the Protestant Reformers Martin Luther and John Calvin.
Muslim conquest and control: By A.D. 700, North Africa, from the Isthmus of Suez to the Strait of Gibraltar, was almost completely dominated by muslims and most of Africa had to wait until the late 1700s and early 1800s for any Christian missionaries.
