Amhara are very funny individuals they like exproriating and plagiarising history.Adal's capital was Zeila which is not and never will be a part of Ethiopia. And it's lands were overwhelmingly in northwest Somalia/Somaliland, Jabuuti and the Somali and Afar parts of Ethiopia.
And, as has been pointed out before, even the southern Ethiosemitic parts of their territory always had a strong connection with Somalis and other eastern Muslim Horners like Afars.
We know they are not the founders axumite empire and civilisation no wonder their hate for tigrayan people who stand between them and their fake history.They have been known to be biased and genocidal on them because their fake solomonic roots myth is busted.
Then comes Oromo people who they claim they came from Madagascar and that they are foreigners.
Then you see how even xabashi wants to descredit somalis from the adal empire and the main aim is to make somalis also become settlers and new arrivals to the horn.
While in reality somalis had a more flouring civilisation than amhara we traded with india arabia persia europe as far china and maldives.
