マリ帝国
During the second half of the 13th century, Gao and the surrounding region had grown into an important trading center and attracted the interest of the expanding Mali Empire. Mali conquered Gao towards the end of the 13th century. Gao would remain under Malian hegemony until the late 14th century. As the Mali Empire started to disintegrate, the Songhai reasserted control of Gao. Songhai rulers subsequently took advantage of the weakened Mali Empire to expand Songhai rule.
