Excerpts from Books and Wikipedia
"Sumanguru remained an implacable enemy of Islam, refusing to allow his people to observe its practices, executing Muslims who fell into his hands. . . . The short-lived Sosso kingdom collapsed. “After the destruction of Sumanguru’s capital,” the Epic concludes, “the world knew no other master but Sundiata.” Sundiata seized control of the old Ghana lands, claimed Kumbi-Saleh as his own, and established his own empire; it became known as Mali. In the Epic of Sundiata, the king of the Keita is an Islamic hero, victor in the war against the animistic and violent Sumanguru . . . He was proclaimed “King of Kings” by the Malinke, and over the next two decades followed Sumanguru’s example, conquering the outlying territories until Mali stretched past Ghana’s old boundaries to unite a new expanse of western African land. . . . Slave traders came down the central trade route to Sundiata’s new capital city, Niani; and Mali grew richer and richer." [Bauer: Renaissance World, p. 207-9]
