languages within the Nilo-Saharan phylum. A 4th-century victory stela commemorative of Axumite king Ezana contains inscriptions describing two distinct population groups dwelling in ancient Nubia: a "red" population and a "black" population. Although Egypt and Nubia have a shared pre-dynastic and pharaonic history, the two histories diverge with the fall of Ancient Egypt and the conquest of Egypt by Alexander the Great in 332 BC. At this point, the area of land between the 1st and the 6th cataract of the Nile became known as Nubia. Egypt was conquered first by the Persians and named the Satrapy (Province) of Mudriya, and two centuries later by the Greeks and then the Romans. During the latter period, however, the Kushites formed the kingdom of Meroë, which was ruled by a series of legendary Candaces or Queens. Mythically, the Candace of Meroë was able to intimidate Alexander the Great into retreat with a great army of elephants, while historical documents suggest that the Nubians defeated the Roman Emperor Augustus Caesar, resulting in a favorable peace treaty for Meroë. The kingdom of Meroë also defeated the Persians, and later Christian Nubia defeated the invading Arab armies on three different occasions resulting in the 600 year peace treaty of Baqt, the longest lasting treaty in history. The fall of the kingdom of Christian Nubia occurred in the early 1500s resulting in full Islamization and reunification with Egypt under the Ottoman Empire, the Muhammad Ali dynasty, and British colonial rule. After the 1956 independence of Sudan from Egypt, Nubia and the Nubian people became divided between Southern Egypt and Northern Sudan. Modern Nubians speak Nubian languages, Eastern Sudanic languages that is part of the Nilo-Saharan family. The Old Nubian language is attested from the 8th century, and is the oldest recorded language of Africa outside of the Afroasiatic family. It was the language of the Noba nomads who occupied the Nile between the First and Third Cataracts and also of the Makorae nomads who occupied the land between the Third and Fourth Cataracts, following the collapse of the Kingdom of Kush sometime in the fourth century. The Makorae were a separate tribe who eventually conquered or inherited the lands of the Noba: they established a Byzantine-influenced state called the Makuria, which administered the Noba lands separately as the eparchy of Nobatia. Nobadia was converted to Miaphysitism by the Orthodox priest Julian and Longinus of Constantinople, and
