"Sara" is the term employed by outsiders to refer to a group of non-Muslim tribes in southern Chad, all of whom speak mutually intelligible dialects. Each tribe is a distinct geographic, political, and endogamous entity. Major tribes are the Kaba, Sar, Nar, Gulay, Ngambay, and Mbay. Most Sara are now, and have been for centuries, located between Lake Iro in the east and the Logone River in the west. Singing and dancing have been and remain an important part of Sara life. Visual arts such as sculpture were little developed.
