Hasan Allahyari

Throughout history, there have been connections between the territories adjacent to the Persian Gulf. The present dissertation examines these connections in the Abbasid period. At the beginning of this period, the center of the caliphate was transferred from Syria to Iraq, and since southern Iraq was adjacent to the Persian Gulf, relations between Iraq and other centers of the Persian Gulf coast entered a new phase. During this period, in addition to long-standing trade relations, these relations took on an increasingly religious, political, and military form. The wide-ranging conflict with the Ibadis in Oman and Qaramata in Bahrain and the expansion of local governments in southern Iran in the Persian Gulf are among the important developments in these relations. This research has been done by descriptive-analytical method and using library resources.
