Mirghanis' principal rival, the Ansar, or followers of the Mahdi, whose present-day leader was Sadiq al-Mahdi, the great-grandson of Muhammad Ahmad, who drove the Egyptian administration from Sudan in 1885. Most other orders were either smaller or less well organized than the Khatmiyyah. Moreover, unlike many other African Muslims, Sudanese Muslims did not all seem to feel the need to identify with one or another tariqa, even if the affiliation were nominal. Many Sudanese Muslims preferred more political movements that sought to change Islamic society and governance to conform to their own visions of the true nature of Islam. One of these movements, Mahdism, was founded in the late nineteenth century. It has been likened to a religious order, but it is not a tariqa in the traditional sense. Mahdism and its adherents, the Ansar, sought the regeneration of Islam, and in general were critical of the turuq. Muhammad Ahmad ibn as Sayyid Abd Allah, a faqih, proclaimed himself to be al-Mahdi al-Muntazar ("the awaited guide in the right path"), the messenger of God and representative of the Prophet Muhammad, an assertion that became an article of faith among the Ansar. He was sent, he said, to prepare the way for the second coming of the Prophet Isa (Jesus) and the impending end of the world. In anticipation of Judgment Day, it was essential that the people return to a simple and rigorous, even puritanical Islam (see Mahdiyah). The idea of the coming of a Mahdi has roots in Sunni Islamic traditions. The issue for Sudanese and other Muslims was whether Muhammad Ahmad was, in fact, the Mahdi. In the century since the Mahdist uprising, the neo-Mahdist movement, and the Ansar, supporters of Mahdism from the west, have persisted as a political force in Sudan. Many groups, from the Baqqara cattle nomads to the largely sedentary tribes on the White Nile, supported this movement. The Ansar were hierarchically organized under the control of Muhammad Ahmad's successors, who have all been members of the Mahdi family (known as the ashraf). The ambitions and varying political perspectives of different members of the family have led to internal conflicts, and it appeared that Sadiq al-Mahdi, the putative leader of the Ansar since the early 1970s, did not enjoy the unanimous support of all Mahdists. Mahdist family political goals and ambitions seemed to have taken precedence over the movement's original religious mission. The modern-day
