 Three Islamic sultanates were founded in and around the area named Shewa (a Semitic-speaking sultanate in eastern Ethiopia, modern Shewa province and ruled by the Mahzumi dynasty, related to Muslim Amharas and Argobbas), Ifat (another Semitic-speaking sultanate located in eastern Ethiopia in what is now eastern Shewa) and Adal and Mora (Gadabursi Clan, Somali, and Harari vassal sultanate of Ifat by 1288, centered on Dakkar and later Harar, with Zeila as its main port and second city, in eastern Ethiopia and in Somaliland's Awdal region; Mora was located in what is now the southern Afar Region of Ethiopia and was subservient to Adal).At least by the reign of Emperor Amda Seyon I (r. 1314-1344) (and possibly as early as during the reign of Yekuno Amlak or Yagbe'u Seyon), these regions came under Ethiopian suzerainty.During the two centuries that it was under Ethiopian control, intermittent warfare broke out between Ifat (which the other sultanates were under, excepting Shewa, which had been incorporated into Ethiopia) and Ethiopia.
