It was a call to Islam, the establishment of an Arab state, and the opening of the door to migration for Arab tribes to imprint the northern regions of Sudan with an Arab-Islamic character. The success of Al-Amri was the optimal incentive for the many Arab migrations to move south in large groups migrating in search of new homelands in the land of Nubia, after the southward migration current had deepened and widened, especially since conditions in Egypt did not encourage Arabs to settle and establish themselves in those regions. They had no choice but to head south, and thus they worked to increase the Arab migration to these lands. From here, it becomes clear to us that Arab migrations are the ones responsible for the first chapter in the spread of Islam and Arabism in the land of Nubia. The spread of Islam and Arabism was a slow phenomenon in that Nubian environment and took a long time, starting from the campaigns of Amr ibn al-As, led by Uqba ibn Nafi al-Fihri, then Abdullah ibn Sa'd Abu Sarh, and after him, the campaign led by Al-Amri, which followed the campaign of Al-Qummi. After that Arab campaign, led by Al-Amri, succeeded in enriching the Arab expansionist movement and the subsequent Arab migrations, it was not a complete conquest, as it was characterized by peaceful Arab migrations, except for the campaigns sent by successive states that ruled Egypt, such as the Umayyad, Fatimid, and Monarchical states, which were entirely responsible for the widespread spread of Islam in the Kingdom of Makuria. From here, Al-Amri's journey and his settlement in the Shangir region and the establishment of what is known as the Arab Islamic Emirate was the opening for Arab tribes to follow suit and move towards spreading Islam. 128
