Abstract
The Arvand River opening was an important strategic waterway that connected the Persian Gulf to Mesopotamia. Except ancient local governments of Kharaks, Kharasan, in the Islamic era, local governments and movements such as the Zangiyan, Baridyan and Qaramatha empowered in the region. Although they do not seem to have much in terms of military troops, but they could have important effects on the Abbasid Caliphate situations. The following article answers this question that what was the economic role of the Arvand river opening in the history of local governments in the Persian Gulf in the time of Caliphate? The theory suggests that the economic position of the opening of the Arvand river had a leading role in the fate of regional governments and the relationships they had with the Caliphate.
