First wave of Sout-To-north Immigartion in Persian Gulf and its adjacent regions

The foremost constant and incessant social development in history of Persian Gulf is “immigration and population displacement” at both sides of this region. This phenomenon is so important that no one may comprehend properly the events and incidents occurred in this region particularly at pre- petroleum exploration regardless of investigation and considering this issue in mind. If we divide Persian Gulf longitudinally in to northern and southern parts by drawing an assumed line, it is clearly obvious that direction of such immigration has been oriented from south to north of yore until the early period of 14th hegira century (20th cen. AD). In the present study, term “north” stands for Iranian current beaches at northern side of Persian Gulf and term “south” denotes seashores at the present countries like Kuwait, Bahrain, Qatar, Saudi Arabia, United Arab Emirates (UAE) and Oman. Although social groups in Persian Gulf have frequently immigrated over the time in this region, but at some part of history and due to certain reasons and factors, a large wave of these immigrations has been brought about and deeply affected on social and political structure at this region. One of the most influencing examples of these immigrations has occurred in ancient period of Iran that is infact considered as “the first wave of south- to- north immigration”. In this study and based on main sources, the first immigration and population displacement in Persian Gulf has been characterized and evaluated as a historical subject.
