Christian Nubia

Around 350 AD, the area was invaded by the Kingdom of Aksum and the Meroitic kingdom collapsed. Three smaller Christian kingdoms replaced it: the northernmost was Nobatia (capital Pachoras; now modern-day Faras, Egypt) between the first and second cataract of the Nile River; in the middle was Makuria (capital Old Dongola), and southernmost was Alodia (capital Soba). King Silky of Nobatia defeated the Blemmyes and recorded his victory in a Greek language inscription carved in the wall of the temple of Talmis (modern Kalabsha) around 500 AD.

Christianity had been introduced to the region by the fourth century: Bishop Athanasius of Alexandria consecrated Marcus as bishop of Philae before his death in 373 AD. John of Ephesus records that a Miaphysite priest named Julian converted the king and his nobles of Nobatia around 545 AD. He also writes that the kingdom of Alodia was converted around 569. However, John of Biclarum wrote that the kingdom of Makuria converted to Catholicism the same year, suggesting that John of Ephesus might be mistaken. Further doubt is cast on John's testimony by an entry in the chronicle of the Greek Orthodox Patriarch of Alexandria Eutychius of Alexandria, which states that in 719 AD the church of Nubia transferred its allegiance from the Greek to the Coptic Orthodox Church. After the official Christianization of Nubia, the Isis cult of Philae remained for the sake of the Nubians. The edict of Theodosius I (390 AD) was not enforced at Philae. Later attempts to suppress the cult of Isis led to armed clashes between the Nubians and Romans. Finally, in 453 AD, a treaty recognizing the traditional religious rights of Nubians at Philae was signed.

By the seventh century, Makuria expanded and became the dominant power in the region. It was strong enough to halt the southern expansion of Islam after the Arabs had taken Egypt. After several failed invasions the new Muslim rulers agreed to a treaty with Dongola, called Baqt, to allow peaceful coexistence and trade, contingent on the Nubians making an annual payment consisting of slaves and other tributes to the Islamic Governor at Aswan; it guaranteed that any runaway slaves were returned to Nubia. The treaty was kept for six hundred years. Throughout this period, Nubia's main exports were dates and slaves, though ivory and gold were also exchanged for Egyptian ceramics, textiles, and glass. Over time the influx of Arab traders introduced Islam to Nubia and it gradually supplanted Christianity. After an interruption in the annual tribute of slaves, the Egyptian Mamluk ruler invaded in 1272 and declared himself sovereign over half of Nubia. While there are records of a bishop Timothy at Qasr Ibrim in 1372, his see included Faras. It is also clear that the cathedral of Dongola had been converted to a mosque in 1317.

The influx of Arabs and Nubians to Egypt and Sudan had contributed to the suppression of the Nubian identity following the collapse of the last Nubian kingdom around 1504. A vast majority of the Nubian population is currently Muslim, and the Arabic language is their main medium of communication in addition to their indigenous Nubian language. The unique characteristic of Nubian is shown in their culture (dress, dances, traditions, and music).
