What country began to rise after the fall of Mali?

Not long after the rule of Mansa Musa ended, the Mali Empire began to grow weak. In the 1400s, the empire began to lose control along the edges of its borders. Then, in the 1500s, the Songhai Empire rose to power. The Mali Empire came to an end in 1610 with the death of the last Mansa, Mahmud IV.

The answer would be hard press.
