Among the important issues of the social history of the Islamic world is the issue of groups known in history as Hashemi, Talebi, Alavi and Sayyid. Each of these titles refers to their era changes throughout history. This group, whose lineage goes back to the Prophet of Islam, has played an important role in the history of the Islamic world under the shadow of this social status. For various reasons, they gradually moved from their main residence in Hejaz and settled in different parts of the Islamic world, including conquered areas. Although their migration to Iran has been seen in various studies, their migration and settlement in the Persian Gulf region has not yet been investigated. This research, using a descriptive-analytical method and using library sources, seeks to describe the migration, distribution and settlement of Alavids in the Persian Gulf region between the second and fifth centuries of Hijra and investigate the causes of this phenomenon.
The results of this research show that the main migration of Alavids to the Persian Gulf region was to Basra, Khuzestan, Bahrain, Siraf, Oman and Yemen. Surveys show that most of the Alawids who migrated to the Persian Gulf region were from Hasani,s Sadat. The presence of Alavids leaders in these areas and references in genealogy books as Sadat's exclusive sources confirm this. The results of this research also show that these migrations are on the one hand due to the frequent political challenges of the Alevis against the Umayyads and Abbasids and the attempt to escape persecution, and on the other hand due to geographical similarities, distance from the areas of influence of the Abbasids and the history of tribal cooperation. It has happened to the Alavids in the Persian Gulf region.
