The Ilemi Triangle is an area of disputed land in East Africa. Arbitrarily defined, it measures between 10,320 and 14,000 square kilometers (3,985 and 5,405 sq mi). Named after Anuak chief Ilemi Akwon, the territory is claimed by South Sudan and Kenya and borders Ethiopia. Despite use and raids by tribes within Ethiopia, the Ethiopian government has never made an official claim on any of the Ilemi and in fact agreed that the land was all Sudanese in 1902, 1907, and 1972 treaties.
Kenya now has de facto control of the area. The dispute arose from unclear wording of a 1914 treaty which attempted to allow for the movements of the Turkana people—nomadic herders who had traditionally grazed the area. The perceived economic marginality of the land as well as decades of Sudanese conflicts are two factors that have delayed the resolution of the dispute.
