 Abdallahi forced warriors of the Western tribes to move to the capital Omdurman and fight for him, sparking rebellions by the Rizeigat and Kababish nomads.Following the overthrow of Abdallahi at Omdurman in 1898, the new (Anglo-Egyptian) Sudan government recognized (1899) Ali Dinar, a grandson of Mohammed-el-Fadhl, as sultan of Darfur, in exchange for an annual tribute of 500 British Pounds.Under Ali Dinar, who during the Mahdi's era had been kept a prisoner in Omdurman, Darfur enjoyed a period of peace and a de facto return to independence.
