'''Sudan''', officially the '''Republic of Sudan'', is a country in the north central part of Africa, just south of Egypt, that was influenced in antiquity by Egypt and later by the Roman empire. Sudan has known Christianity from the early centuries after Christ. Christianity reached Nubia, now northern Sudan, during the second century after Christ.
