Garus rises and falls in the structure of Iran’s administrative divisions (Based on theory of power)

Garus, which many people know by the name of Amir Nizam Garusi (the ruler of the Qajar period), according to the available sources, is an area of 1700 to 1800 square kilometers and one of the main components of the structure of the country divisions of western Iran from the beginning of the Safavid to the middle of the Pahlavi period. This region was sometimes under the rule of Kurdistan and in most times was governed by an independent ruler. The present article, based on official and unofficial documents in a historical-referential method, has sought the position of this region by emphasizing its name in the structure of Iran's administrative divisions.The results show that the official application of the name Garus to this region was common frombefore the Safavid period to the middle of the Pahlavi period and after that, although it remained in the cultural memory, it was identified with the name of Bijar in the geographical structure of Iran. The author tries to express the stages of presence, application and official removal of this geographical name among official and unofficial correspondences, approvals, documents and sources in the structure of Iran's country divisions. It seems that Garus tribe’s power in the Safavid period and after that Amir Nizam Garusi’s position in the Qajar period, in the application of Garus and the promotion of this region and the decline of the tribe’s power played a decisive role in changing its name.
