In the turbulent period of the 12th century (18 A.D), which is unique in terms of chaos and rebellion of tribes and nomads, led to the destroyed the security of roads and places, and delayed the normal life of survivors in various parts of western Iran. This research, which has been drafted in a historical way, has been proposed by the question of how and in what way is the process of establishing security in the Chaharmahal and Bakhtiari region by Karim Khan? In response to this question, the research hypothesis is that Karim Khan Zand has been using various methods such as the encouragement, granting of tax liability and the assignment of local order and security to Khans, to enforce sovereignty over the Chaharmahal and Bakhtiari and to create order and security. Other tactics, such as the policy of displacing tribes and nomads or taking hostages their heads, were also used. The findings of the research show that this process in the local dimension has caused relative security and prosperity of the North-South communication, and in the country level, with the expansion of Khan Zand, it had a huge impact on the organize of peasantry, businessmen and travelers.
