Dervish War
1900–1920
The Dervish War was a conflict in the Horn of Africa, between the Dervish State, and the imperial powers of Abyssinia, Britain and Italy, initially from 1900 to 1904, which was followed by a peace treaty-protectorate period with the Italians from 1905, other diplomatic measures in the following years, and a resumption of conflict with the colonial powers from 1913 to 1920. The opening battle of the rebellion saw the Dervish attack the Ethiopian garrison at Jigjiga in March 1900 and take control of parts of the eastern Ogaden region.
