The first post offices to be opened in Sudan were in 1867 at Suakin and Wadi Halfa; in 1873 at Dongola, Berber and Khartoum; and in 1877 at Sennar, Karkouk, Fazoglu, Elkedaref, El Obeid, Al-Fasher and Fashoda (now Kodok). The Mahdist revolt, which began in 1881, resulted in all Egyptian post offices being closed by 1884. It culminated in the fall of Khartoum and the death of the British governor General Gordon (Gordon of Khartoum) in 1885. The Egyptians and British withdrew their forces from Sudan and the country was left with no postal service until the reconquest of Sudan began in 1896. When the campaign started in March 1896, postal service was made available to the troops but no stamps were used.
