After their defeat, the Arabs withdrew from Nubia and something of a peace had been established by 645. According to the 14th-century Arab-Egyptian historian al-Maqrizi, Makuria did something to violate the truce. It was then that Abdullah Ibn Sa'ad, the successor of the first governor of Arab Egypt, invaded Makuria in an attempt to bring the Makurians to heel. At this time, northern and central Nubia were united under the Makurian king Qalidurut."@en . . . "Makurian victory; Baqt between Makuria and Rashidun Caliphate"@en . "Second Battle of Dongola"@en .
