100% agree. While reading Futah Al Habesh I was very surprised to see how arabized the Somali and Harla clans were. Seemed so alien to todayYes exactly and that was in the middle ages. I think a better premise for your thread would be if Adal never fell apart and continued to rule the Somali lands as they were very Arabized and a centralized state would have spread the Arabic language among the masses. A centralized state is the next best thing in implementing a language shift as Arabic would be the lingua franca among the different ethnic groups under Adal rule.
