The Mahdist War, which began in 1881, was a period of intense conflict and upheaval in Sudan. The Mahdist forces, led by Muhammad Ahmad, successfully overthrew the Egyptian-Ottoman rule and established their own state. This period was marked by significant battles, including the siege of Khartoum and the Battle of Omdurman, which ultimately led to the Mahdist defeat at the hands of the Anglo-Egyptian forces in 1898. The war had a profound impact on the social, political, and economic landscape of Sudan, shaping its future trajectory.
