Didn't harar break off eventually from Aussa during the 1600s and become it's own state?That is a completely retarded comparison, a better one would be Rome and Byzantium, and when the west of Rome fell, Byzantium was the continued empire and it was called the eastern Roman empire
And Harar never fell to the hands of the christians, they constantly repelled the Oromo attacks but the problem was they got raided too much so to ensure safety and stability for the kingdom the capital was moved to Aussa, it was still Adal, if the capital of the US changes from Washington to Minneapolis will it cease to be the US?
And Harar was part of Adal why did you mention them separately
