You may also be looking for the abbreviation IK.
The Ik (also derogatorily called Teuso) are a tribe living in the mountains of northeastern Uganda, next to the larger Dodoth and Turkana, numbering a few thousand. They were expelled from their land to create a national park, and as a result of this suffered extreme famine; furthermore, their weakness relative to other tribes meant they were regularly raided. Colin Turnbull wrote an extremely disparaging anthropology book about them called The Mountain People. Their language, the Ik language, is of interest to linguists as a member of the highly divergent Kuliak subgroup of Nilo-Saharan.
