H.A. MacMichael [1882-1969] was a dominant figure in the history of the Anglo-Egyptian Regime in the Sudan. He served there from 1905 to 1933: from early 1906 until 1912 in the Kordafan, in 1916 as political officer with the Darfur Field Force, and in 1917-1918 as sub-governor of Darfur, he had long experience of Kordafan during the formative period from him and it.He published, among many books, The Tribes of Northern and Central Kordafan [1912] and A History of the Arabs of the Sudan [1922], both long considered authoritative works.With the arguable exception of Sir Reginald Wingate and Sir Douglas Newbold, he was the most important British Administrator of the Sudan.
