Roman Africa or Roman North Africa is the culture of Roman Africans that developed from 146 BC, when the Roman Republic defeated Carthage and the Punic Wars ended, with subsequent institution of Roman Imperial government, through the 5th and 6th centuries AD under Byzantine Imperial control. In referring to "Africa", the Romans themselves meant mainly northern Africa or Mediterranean Africa, with Roman Egypt a separate province having a distinct Greco-Egyptian culture and society, and Aethiopia representing the largely unknown bounds of sub-Saharan Africa. The loose geography of "Roman Africa" encompasses primarily present-day Tunisia, Algeria, Libya, and northern Morocco.
