 The Sultanate of Aussa (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 Aussa and Sultanate of Harar.At some point after 1672, Aussa declined and temporarily came to an end in conjunction with Imam Umar Din bin Adam's recorded ascension to the throne.
