Dunama IV

Dunama IV (Dunama bin ʿUmar ) was mai (ruler) of the Kanem–Bornu Empire in the early 15th century, ruling approximately 1423–1425. (Different king lists (girgams) and chronicles translated in the 19th–20th centuries assign Dunama a reign of 2 years (Barth, Palmer, Urvoy) or 4 years (Landeroin, Nachtigal).) As a result of this, and due to different calculations for other mais, various dates have been given for his reign, including 1433–1434 (Barth), 1425–1427 (Palmer), 1422–1424 (Urvoy), 1407–1411 (Landeroin), and 1435–1439 (Nachtigal). Stewart dated it to 1433–1435, According to the girgam (royal chronicle of the empire), Dunama's horses "were to him as mothers".

Dunama ruled for two or four years. He was murdered at a site recorded as Nánigham and succeeded as mai by his brother Abdullah III Dakumuni.
