Dunama I
Dunama (1092-1150) was the third Mai, or king, of the Sayfawa dynasty of Kanem-Borno. He succeeded his father Mai Hummay in 1097 when he died in Egypt on the hajj. Dunama made the pilgramage twice in his own right, each time leaving 300 slaves in Egypt as gifts for his hosts. All Mais of Bornu named Muhammad are also called Dunama (and vice versa). The name likely came from a compound of Dun ("power" or "might" in Kanuri) and Aman (i.e, Ammon) the Berber god, according to historian H.R. Palmer. References
