In Baghdad there were many Abbasid military leaders who were or said they were of Arab descent. However, it is clear that most of the ranks were of Iranian origin, the vast majority being from Khorasan and Transoxiana, not from western Iran or Azerbaijan. Most of the Khorasani soldiers who brought the Abbasids to power were Arabs.
