Causes of the 16th Century Military Campaigns of the Oromo

This chapter reevaluates the socio-political and geostrategic catalysts behind the expansive 16th-century military campaigns of the Oromo nation. Rejecting imperial narratives that essentialize these movements as barbaric incursions, Demmeksa instead frames them as reactive and preemptive mobilisations against dual encroachments by Christian highland monarchies and Islamic sultanates. Through rigorous historical excavation, he reveals that the Oromo campaigns emerged as rational responses to regional destabilisation, religious proselytisation, and ecological pressures. The chapter places the Oromo within a pan-African tradition of defensive statecraft, grounded in indigenous governance and collective survival.
