Adal Sultanate
The city Dire Dawa was originally called Dir Dhabe and used to be part of Adal Sultanate during the medieval times and was exclusively settled by Dir which is a major Somali tribe and after the weakening of Adal Sultanate, the Oromos took advantage and were able to penetrate through the city and settle into these areas and also assimilate some of the local Gurgura clan.
