عبد الله التعايشي
The Mahdi and a party of his followers, the "Ansār" (helpers, known in the West as "the Dervishes"), made a long march to Kurdufan. There he gained numerous recruits, especially from the Baqqara, and notable leaders such as Sheikh Madibbo ibn Ali of the Rizeigat and Abdallahi ibn Muhammad of the Ta'aisha tribes. They were also joined by the Hadendoa Beja, who were rallied to the Mahdi in 1883 by Osman Digna, an Ansār captain in east of Sudan.
