Ali V Minargema

Ali V (ʿAlī bin Ibrāhīm), called Ali Minargema and Ali Delatumi, was the last mai of the Kanem–Bornu Empire, ruling in 1846. Ali was installed as mai by the Wadai Sultanate during a power struggle with shehu Umar Kura over control of the empire. His defeat and death was followed by Umar Kura abolishing the office of mai, which had existed for over a thousand years, and assuming sole power over the empire.
