South of these pure Ja'aliyyin, there is a branch or clan, the Jum'iyya, who inhabit the area south of Khatm Salbuqa on the west bank of the Great Nile, north and south of Omdurman. Their homelands extend for more than fifty kilometers south of present-day Omdurman, and most of them live on the west bank of the White Nile and the Great Nile River. Also, there is a small branch of the Ja'aliyyin, the Jum'a or Jum'iyya, who reside in the area west of the White Nile, south of the residential area of the Kawkala tribes, who belong to Juhayna. There is also the Badriyya tribe, a large branch of whom has descended and lives on the Nile, while another branch took its way westward to the Kordofan region, where they found a place to settle. It appears that their descent into these western regions of Sudan did not occur until the 14th century AD, the 8th Hijri century, at the time when the Arabs were able to destroy the Kingdom of Makuria in Dongola, and then they continued their pursuit in movement and migration.

Old Dongola was their largest kingdom, and all other kingdoms were like subordinate emirates. The Badriyya and Nubians settled these lands, and the province of Korti was inhabited by the Tariqa tribe, who had a close kinship with the Badriyya. The original homeland of the Badiriyya is on the Nile, north of the land of the Shayqiyya and south of the Jawabra. In the early 14th century, some of them migrated to Kordofan and settled around the White Nile, practicing agriculture, herding, and trade. There is also another tribe that took the same course of westward migration south of Kordofan and Darfur, although they settled south on the banks of the 248
