Adamawa Plateau
Adama allied with forces from Kanem-Bornu to pursue the Mandara people. He led the charge to conquer Guider by 1810, then he moved on the Mandara capital of Douolo. Adama took these settlements and other smaller ones. The remainder of the Mandaras fled to the mountains that today bear their name. Adama had reached well into the Adamawa Plateau by 1825.
