Adal Sultanate - Gadaa Expansion

Gadaa Expansion

After the conflict between Adal and Ethiopia had subsided, the conquest of the highland regions of Ethiopia and Adal by the Oromo (namely, through military expansion and the installation of the Gadaa socio-political system) ended in the contraction of both regional powers and changed the dynamics of the region for centuries to come. In essence, what had happened is that the populations of the highlands had not ceased to exist as a result of the Gadaa expansion, but were simply incorporated into a different socio-political system.
