Are the Harari somali? They seem very somali adjacent. Like a lost tribe.
Harari are an ethnicity of the city of Harar which was the home of Islam in the horn. It was the capital of the Adal empire.
The ethnicity started to form after the futuh in 1500s when a Somali Sultan of the city built a wall around to keep the Oromo out, who started migrating all around the region after the weakened adal sultanate.
The people already within the city like Somalis, Various Habasha, a few Yemeni traders, and other tribes. Who were stuck together in this city, Mixed together over centuries to form this Islamic ethnic group we now call harari after the city. For some reason the Semetic influence in language was stronger which is why it's Harari called Ethio Semetic. However it's got lots of influence from all languages that were within including Somali.
After Menelik II took the city and forced the sultanate of Harar to surrender their state. The abyssinnians started a process of dismantling harar. Which stood as the house of Islam in the horn treasured by muslims including somalis, and was the base of some of the greatesg sultanates. Who fought Ethiopia.
Eventually the walls were opened and Oromo especially started flooding the city after being held outside for centuries. Christianity penetrated the city as well due to habash. As shown before Halie Salassie genocided hararis and forced many out. Which is ironic since Haile Selassie was born and raised in harar around Hararis, Somalis & Oromo which he all later Opressed.
