The Sultanate of Aussa or "Afar Sultanate" succeeded the earlier Imamate of Aussa. The latter polity had come into existence in 1577 when Muhammed Jasa moved his capital from Harar to Aussa (Asaita) with the split of the Adal Sultanate into the Sultanate of Aussa and the Sultanate of Harar. At some point after 1672, the Sultanate of Aussa declined and temporarily came to an end in conjunction with Imam Umar Din bin Adam's recorded ascension to the throne.
