The Igala are found in the extreme East of Kwara state. The rivers Benue and Niger form their northern and western boundaries and they share their eastern border with the Idoma and the southern with the Onitsha Igbo. The northern part of Igala country is occupied by the Nupe speaking Bassa-Nge and the Bass-Komo. South of Idah live the Ibaji, a mixed Igbo and Igala people. The Igala are related linguistically to the Yoruba. Their principal town is Idah and their chief is called Ata. Their principal cult, Egu is connected with the ancestors who are remembered during yam harvest. The Egu (spirit of the dead) may be represented by masks and head dress called Ojuegu.
