Aimed at disseminating academic knowledge for a comprehensive, multidimensional, and multilayered view of the Persian Gulf, this edited volume (as a selection of chapters presented by academics, researchers, and experts) explores various aspects and characteristics of the Persian Gulf by initiating an in-depth discussion through representative chapters on historical perspectives, the Maritime Silk Road, and hydropolitics. It examines the Persian Gulf from the Sassanid period (Sasanian Empire, the third to seventh centuries AD) and port trade with the Indian subcontinent during this period. Then, the Persian Gulf region is considered during the Seljuks and Solqori⁠ era in the eleventh to twelfth centuries AD. Also, the historical impact of the tribal and clan systems on the insecurity of the Persian Gulf ports in the first half of the twentieth century is investigated. Subsequently, with regard to the present era, in order to increase the level of cooperation and political and cultural convergence of the Persian Gulf countries, the effects of the revival of the Maritime Silk Road on the cooperation and cultural-civilization links of these countries are investigated. Then, the importance of the military position of the Persian Gulf and the border challenges in this region are analyzed. Finally, since water as one of the sources of geographic power can play a significant role in regional relations, the hydropolitics of the Persian Gulf region is introduced and discussed, and the possibility of future wars over access to water resources is warned. It calls for a realistic approach to create peace and convergence in access to freshwater resources. In each chapter of the book, authors with expertise in their chosen topic have tried to reveal different aspects of the Persian Gulf that can be useful not only for academics and researchers but also for policy-makers. It is hoped that this book will appeal to a wide range of global audiences, researchers, academics, and policy-makers; satisfy scholarly and intellectual interests; provide creative discussions in the Persian Gulf studies; add insight for better understanding; and serve as a useful reference work in the service of regional peace, as well as the resulting global peace.
