Mande Bori
Mande Bori, also called Abu Bakr in Arabic, was a hero of Mande oral tradition and the brother and right-hand man of Sundiata Keita. He was raised by Sogolon Condé, shared the family's exile, and fought in the wars against the Sosso, including the Battle of Kirina in 1235.
After Sundiata founded the Mali Empire, he held the office of kankoro-sigui, or viceroy. He never reigned himself, but his grandsons Mansa Musa and Mansa Suleyman later ruled Mali.
