The origins of the Sudanese Army can be traced to Sudanese soldiers recruited by the British during the reconquest of Sudan in 1898. Sudan officially became the Anglo-Egyptian Sudan in 1899. The highest-ranking British officer in Egypt, known as the Sirdar, also served as Governor General of the Sudan. In 1922, after nationalist riots stimulated by Egyptian leader Saad Zaghloul, Egypt was granted independence by the United Kingdom. The Egyptians wanted more oversight in the Sudan and created specialized units of Sudanese auxiliaries within the Egyptian Army called Al-Awtirah. This became the nucleus of the modern Sudanese Army.
