You can only claim pre 16th cemtury/Oromo Expansion borders. There are no proof Oromos are indeginous to Bale, the Sidama and the Hidaya and Somalis are. Sheikh Hussein that y'all love to claim founded the Bale Sultanate in the 13th century. that 300 years before Oromos.Adama is Oromo
Prove to me that Gallas as they were first described as existed before the 16th century.
