Arab-Ethiopian War (Principia Moderni IV Map Game)

The Arab-Ethiopian War was a conflict in East Africa between the Muslim Abbasid Caliphate and the Coptic Empire of Ethiopia. Originally a war of conquest against the last stronghold of Christianity on the continent, the war ultimately spiraled into a much bloodier conflict, ultimately sparking the Humanist movement in the Caliphate. After the war, although Ethiopia was annexed, the Caliphate quickly transitioned to an elective system of government as a result.
