Reign

The reign of Mansa Sundiata Keita saw the conquest of several key places in the Mali Empire. He never personally took the field again after Kirina, but his generals continued to expand the frontier, especially in the west where they reached the Gambia River and the marches of Tekrur. This enabled him to rule over a realm larger than even the Ghana Empire in its apex. When the campaigning was done, his empire extended 1,000 miles (1,600 km) east to west with those borders being the bends of the Senegal and Niger rivers. After unifying Manden, he added the Wangara goldfields, making them the southern border. The northern commercial towns of Oualata and Audaghost were also conquered and became part of the new state's northern border. Wagadou and Mema became junior partners in the realm and part of the imperial nucleus. The lands of Bambougou, Jalo (Fouta Djallon), and Kaabu were added into Mali by Fakoli Koroma (known as Nkrumah in Ghana, Kurumah in the Gambia, Colley in Casamance, Senegal), Fran Kamara (Camara) and Tiramakhan Traore (Trawally in the Gambia), respectively.
