Khalifa of Mali
Khalifa was the fourth mansa of the Mali Empire, known only from Ibn Khaldun's Kitāb al-ʻIbar. The chronicler makes him a son of Sundiata Keita, ruling late in the thirteenth century after his brothers Mansa Wali and Wati.
He describes Khalifa as insane and devoted to archery, shooting his subjects for sport, until they rose and killed him. The throne then passed to Abu Bakr, a grandson of Sundiata, and his brief reign is placed around 1273–1275.
