Abdallahi ibn Muhammad

Following Muhammad Ahmad's death, Abdallahi ibn Muhammad succeeded him as Khalifa (successor) of the Mahdist state. He consolidated power by eliminating rivals and establishing a military dictatorship based on his Ta'aisha tribe.

Anglo-Egyptian forces under General Herbert Kitchener defeated the Mahdist army at Omdurman on September 2, 1898. The battle resulted in over 10,000 Mahdist casualties and effectively ended the Mahdist state's control over Sudan.

Abdallahi ibn Muhammad was killed in action at the Battle of Umm Diwaykarat on November 25, 1899. His death marked the final defeat of the Mahdist movement and the establishment of Anglo-Egyptian condominium rule over Sudan.
