The Ilemi Triangle, sometimes called only Ilemi, is a disputed area in East Africa. Arbitrarily defined, it measures about 11,000 square kilometres (4,200 sq mi).^[1] The term "Ilemi" may more accurately be transcribed as "Elemi" in the Didinga language, signifying acceptance. This suggest that, in Didinga history, the region became favorable when they arrived, evidenced by the thriving health of the cattle that accepted the local vegetation, indicating a symbiotic relationship between the cattle's well-being and the area. The territory is claimed by South Sudan and Kenya. The territory also borders Ethiopia and, despite use and trespass into the triangle by border tribes from within Ethiopia, the Ethiopian government has not made any official claim on the area, instead agreeing that the land was Sudanese territory in the 1902, 1907, and 1972 treaties.^[2][3][4]

Kenya now has de facto control of all the territory in the Ilemi Triangle up to the northern 1950 Sudanese Patrol Line.^[5] The dispute arose from the 1914 treaty in which a straight parallel line was used to divide territories that were both part of the British Empire. However the Turkana people—nomadic herders—continued to move to and from the border and traditionally grazed in 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.
