Uthman III (ÿUthmÃÂn bin DÃÂwà «d), called Uthman Kalinumuwa and Uthman Daudumi, was briefly mai (ruler) of the KanemâÂÂBornu Empire in the early 15th century, ruling approximately 1422âÂÂ1423. Uthman ruled during the "Era of Instability", a chaotic period of internal and external conflict in the empire.
Uthman was a son of mai Dawud Nikalemi. Uthman became mai in the early 15th century, succeeding his cousin Biri III Uthman.
Uthman's reign was very brief, perhaps shorter than a year. He was overthrown by a party led by the kaigama (chief general) Nikale bin Ibrahim and the yerima (another high official) Kade. Uthman fled from the country and sought refuge among the Hausa states, probably in the Kingdom of Kano. Uthman was succeeded as mai with Dunama IV, a nephew of Biri III.
Uthman probably died in his place of exile, presumably Kano. The site of his death has also alternatively been recorded as "Bursulum".
