"The Mahdist War, which began in 1881, was a significant event in Sudanese history. The Mahdist uprising, led by Muhammad Ahmad, challenged the Egyptian-Ottoman rule and eventually led to the establishment of the Mahdist State. The war was characterized by intense fighting and significant political and social upheaval. The Mahdist forces achieved notable victories, including the capture of Khartoum in 1885. However, the Mahdist State faced internal challenges and external pressures, ultimately leading to its downfall at the Battle of Omdurman in 1898."
