In the vast part of the seventh century, the province of Kerman, extending to the Gulf coast, was under the rule of the Qarakhtayans. The fourth ruler of this dynasty Tarkhan Khatun, which ruled from 655 to 681 AH, was one of the most famous and influential rulers of the family. In the present study, the policies and practices of Tarkhan Khatun and its effects on the Persian Gulf developments are examined. Tarkhan Khatun pursued fair and just policies, established stability and security, and built lobbies and caravanseras. Thus, the travel and communications ties between Harmuz, Kerman and neighboring states, including Fars and Yazd, improved, thereby helping to develop economic and cultural ties between the Persian Gulf and the border areas and postwar.
