Similarly, the treaty with Shkenda, stipulating that Arabs would not be allowed to settle in his land, shows us that the Mamluk policy towards the Arabs made them flee to Nubia, south of Alwa, to the region of Al-Abwab. Repeated famines and the plague that accompanied the first Mamluk era also encouraged many Arabs to flee to Nubia for fear of annihilation. Several migrations occurred due to the spread of diseases. This epidemic and famines had a negative impact on the general economic situation. All this was accompanied by an increase in taxes to confront the Mongol invasion. Furthermore, many agricultural lands were confiscated for the Mamluks, leaving those who sought them in a worse state than before. All these reasons encouraged the Arabs to migrate to Sudan. Many of them also accompanied the Mamluk campaigns that invaded Nubia, as we have previously mentioned.

Historical treaties state that the Mamluk campaign, which accompanied the Emir, that campaign in 744 AH/1267 AD, considered the land independent. Thus, Egyptian policy succeeded in making Nubia subordinate to Egyptian rule. This policy helped spread Islam on a wide scale, and the Arabization movement appeared clearly and visibly throughout the country, which had begun long ago in Nubia. This treaty also helped many Arab tribes enter with the conquering Arab armies and settle in Nubia, contrary to what Sultan Baybars wanted. They married the people of Nubia and its ruling families until they took control in the early eighth century AH, the fourteenth century AD.

Despite the covenants and treaties that Shkenda made with himself to work under the Mamluk banner, Sultan Baybars sent a group of Ismailis to Dongola to monitor him, so that he would not think of rebelling against Mamluk authority in Cairo. 824
