The Sultanate of Harar was an ancient kingdom centered in Harar, Ethiopia. It succeeded the Adal Sultanate. In this period the Harar Sultanate led by Amīr Nūr continued to carry on the struggle of the Adal leader Imām Aḥmed Gurēy against the Abyssinian Empire. Due to the encroaching Oromo people invading from the south and Somali threats in north east blocking Harar's coastal influence, the Sultanate of Harar was ultimately a short lived state, lasting only 18 years (though if you start from the reign of Imām Aḥmed Gurēy, a more respectable 51 years). The capital was moved east to the oasis of Aussa by Imām Maḥamed "Jāsa" Ibrahim who founded the Imamate of Awsa.
Also known as Ahmed Gurey or Ahmed Gran. The conqueror, cousin of Garād Abūn ʿAdādshe of Hubat. He ruled Adal in all but name and launched a conquest of the Ethiopian highlands. While not technically a Sultan of Harar, no list is complete without him.
