[2] The Ajan Coast appears prominently in the times of Adal Sultanate as a land of multiple kings, deserts and a long coastline with two capitals at Mogadishu and Zeila.
[3] However, the overlapping analysis frequently places the core of Ajan Coast in the region of the plains beyond the promontory (Ras Hafun) that follows the Horn's headland.
The Ajan Coast was bordered to the north by Aromata, to the west by Rauso, to the south by various peoples including the Zanj and Tunni and to the east by the Indian Ocean.
