Khorasani Arabs

Khorasani Arabs are Iranian Arabs descended from Arab settlers who migrated to the Khorasan region during the early Islamic conquests and the Abbasid Caliphate (8th century onward). These settlers, often of South Arabian (Yamani) tribal origin, played a pivotal role in the Abbasid Revolution (747–750), forming the core of the revolutionary forces (ahl Khurāsān) that helped establish the Abbasid Caliphate and later became the elite military backbone (abnāʾ al-dawla) of the early Abbasid regime. Over the centuries, they assimilated culturally and linguistically, with most speaking Persian and only a few retaining Khorasani Arabic as their native tongue.
