The Dervish movement, which began in the Sudan in the late 19th century, was a religious and political uprising against foreign domination. Led by Muhammad Ahmad, who proclaimed himself the Mahdi (the guided one), the Dervishes gained widespread support among the Sudanese people, who were disillusioned with the corruption and inefficiency of the Turco-Egyptian rule. The Mahdi's forces achieved significant victories against the Anglo-Egyptian army, culminating in the capture of Khartoum in 1885. However, the Mahdist state was short-lived, and the movement was eventually crushed by the British at the Battle of Omdurman in 1898.
