paragraph_text: Mahdist War
  
  During the 1870s, European initiatives against the slave trade caused an economic crisis in northern Sudan, precipitating the rise of Mahdist forces. In 1881, the Mahdist revolt erupted in Sudan under Muhammad Ahmad, severing Tewfik's authority in Sudan. The same year, Tewfik suffered an even more perilous rebellion by his Egyptian army in the form of the Urabi revolt. In 1882, Tewfik appealed for direct British military assistance, commencing Britain's administration of Egypt. A joint British-Egyptian military force entered the Mahdist War. Additionally the Egyptian province of Equatoria (located in South Sudan) led by Emin Pasha was also subject to an ostensible relief expedition of Emin Pasha against Mahdist forces. The British-Egyptian force ultimately defeated the Mahdist forces in Sudan in 1898. Thereafter, Britain seized effective control of Sudan, which was nominally called Anglo-Egyptian Sudan.
