BS the Oromo invasion is quite recent, the Arab migrants were a minor factor that existed in port cities and not in the interior. A german explorer discovered Somalis hated Arabs, Egyptian, Turks due to invasion of King Salim and his father. There are remnants of their coins all over the Ogaden region mainly Hawd area. This shows you they have for a period colonized Somalis.Ifat was Habesha and Oromo kingdom that began in Shewa. It was situated near Walaale town in Oromia.
Founded by the Makhzumis it was later taken over by the Walashma dynasty.
It consisted of Habesha, Oromo and Arab migrants.
But this is quite some time after Adal the explorer was in the area 1800s, Somalis killed alot of explorers that ventured into their land in the 1800s, at that time Harar was a Habashi shit hole.
in the 1930s when the Italians invaded Ethiopia and captured Harar, they found thousands of Somalis in chains in Harar jails. there has been extermination of Somalis at the hands of Abyssinian for centuries.
