The Ethiopian-Adal War was a conflict that took place in the 16th century between the Ethiopian Empire and the Adal Sultanate. The war was primarily driven by territorial disputes and religious differences, as the Ethiopian Empire was predominantly Christian, while the Adal Sultanate was mainly Muslim. The conflict escalated around 1529 and lasted until 1543, involving significant battles and the use of advanced military tactics. Notable figures in the war included Emperor Menas of Ethiopia and Ahmad ibn Ibrahim al-Ghazi, the leader of the Adal forces. The war ultimately ended with the defeat of the Adal Sultanate, solidifying Ethiopian control over the region.
