The Mahdist Revolt was a significant uprising in Sudan that began in 1881, led by Muhammad Ahmad, who claimed to be the Mahdi, a messianic figure in Islam. The revolt aimed to establish a theocratic state free from foreign influence, particularly against the rule of the Anglo-Egyptian administration. The movement gained widespread support among the Sudanese population, who were discontented with colonial rule and economic hardships. The conflict escalated into a series of battles, culminating in the capture of Khartoum in 1885, where British General Charles Gordon was killed. The Mahdist state lasted until 1898 when it was defeated by British and Egyptian forces at the Battle of Omdurman, leading to the re-establishment of British control over Sudan.
