The Harla, an extinct Afro-Asiatic people native to Hararghe, are considered the precursors to the Harari people.[3][4] The ancestors of the Hararis moved across the Bab-el-Mandeb, entering the shores of north Somalia from Arabia, producing a Semitic population among Cushites and Hamites in what would become Harar.[5][6] Upon the arrival of the Arab Fagih Abadir, the alleged patriarch of the Harari in the 10th century, he was met by the Harla, Gaturi and Argobba tribes.[7] By the thirteenth century, Hararis were among the administrators of the Ifat Sultanate.[8] In the fourteenth century raids on the Harari town of Get (Gey) by Abyssinian Emperor Amda Seyon I, Hararis are referred to as Harla Arabs.[9] During the Abyssinian-Adal war, some Harari militia settled in Gurage territory, forming the Silt'e ethnic group.[10] Hararis once represented the largest concentration of agriculturalists in East Africa.[11]
