From Atbara, Kordofan, and Sennar, branches of them continued their migration, reaching the White Nile, then Kordofan. Some of them live in the Nuba Mountains. It is mentioned that the Shayqiyya tribes are attributed to Shayq, who is the brother of Ghanim, the ancestor of the Ja'aliyyin. The Ja'ama'a and Fadiyat tribes are found, and they participated with the Funj in their expansion towards Kordofan. The Shayqiyya live on both banks of the Nile from the end of the Fourth Cataract to the mouth of Wadi al-Muluk. They entered Sudan via Suakin and Ma'aw'a and headed west and south in a basin towards the Nile. The Shayqiyya became a strong tribe with influence and authority, as they were able to unite the Sultanate of Sennar, as well as the Funj and the Adlab. By the twelfth Hijri century, the eighth AD, the Shayqiyya had rebelled against their allegiance to the Sultanate of Sennar and aspired to fame. This was one of the decisive factors in the history of Sudan. Sudan also includes a group of tribes distributed between Fazarah and the Ja'aliyyin, among whom are the Rabataab, Al-Jam'iyyah, Al-Budayriyyah, Al-'Adiyyat, and Al-Battahin. In addition, there is the recent migration of the Rashaida in the nineteenth AD century, the thirteenth Hijri century, who migrated from the Hijaz and spread in the region of the western Red Sea coast. Therefore, it can be said that the numerous Arab tribes currently spread throughout Sudan, whether large origins, sub-tribes, branches, clans, or small tribes, is something that cannot be precisely enumerated or fully grasped except by those interested in ethnology and genealogy. This requires detailed study, a study that this field may not accommodate, given that the groups we have mentioned may have played a prominent role in the history of Islam and its widespread dissemination in Sudan, as well as in the Arabization of that homeland so that 336
