Abdallahi ibn Muhammad

Abdullah ibn-Mohammed al-Khalifa or Abdullah al-Taashi or Abdallah al-Khalifa, also known as "The Khalifa" was a Sudanese Ansar ruler who was one of the principal followers of Muhammad Ahmad. Ahmad claimed to be the Mahdi, building up a large following. After Ahmad's death, Abdullah ibn-Mohammed took over the movement, adopting the title of Khalifah al-Mahdi. He attempted to create a kingdom, which led to widespread discontent and his eventual defeat and death at the hands of the British and Egyptians.
