The population of Arbayistan was primarily composed of Arameans, who spoke the Aramaic language, and shared the province with Jews, Arabs, Armenians and Iranians. Many Arabs lived as nomads throughout the province, however they are known to have also thrived in the city of Hatra. Armenians could be found largely in the north of Arbayistan, in the districts of Arzanene, whilst Iranian tribes lived in the north-eastern districts of Corduene.[2]
