I want to know the answer to the following question:
When was the Aussa Sultanate established?
All the background I'm provided with is that "The 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 the Sultanate of Harar.". Is that enough to answer the question?
Answer: no
