About Khalifa

Khalifa was a 13th-century Mansa of the Mali Empire mentioned by the medieval Arab scholar Ibn Khaldun. All that is known of Khalifa's life comes from a brief mention in Ibn Khaldun's Kitāb al-ʻIbar:[Mārī Jāṭa] ruled for 25 years, according to what they relate, and when he died his son Mansā Walī ruled after him...His brother Wātī ruled after him and then a third brother, Khalīfa. Khalīfa was insane and devoted to archery and used to shoot arrows at his people and kill them wantonly so they rose against him and killed him. He was succeeded by a sibṭ [son of a daughter] of Mārī Jāṭa, called Abū Bakr, who was the son of his daughter.
