Mahdia* mud-walls in Omdurman.
Al-Mahdiah* is a religious movement in Sudan from 1881 to 1898, established by Muḥammad Aḥmad and ʿAbd Allāh ibn al-Mahdī, with the aim to reform Islam. The movement, which succeeded in overcoming the unpopular ruling of the Turco-Egyptian regime in Sudan, resulted in the establishment of a Mahdist state in 1885. Shortly thereafter, Muḥammad Aḥmad passed away and ʿAbd Allāh ibn Muḥammad succeeded to leadership of the movement and the nascent state. It was then conquered by the British in 1898.
