The name Early African Church is given to the Christian communities inhabiting the region known politically as Roman Africa, and comprised geographically somewhat around the area of the Roman Diocese of Africa, namely: the Mediterranean littoral between Cyrenaica on the east and the river Ampsaga (now the (fr)) on the west; that part of it that faces the Atlantic Ocean being called Mauretania, in addition to Byzacena. Thus corresponding somewhat to contemporary Morocco, Algeria, Tunisia and Libya. The evangelization of Africa followed much the same lines as those traced by Roman civilization.
