AbstractLocal and unpublished documents, especially those formed in the process of the lord-peasant system, play a great role in the reconstruction of social history and local history, due to the evidence and detailed data in them. The documents of the Vaziri family are a collection of local and unpublished documents of Kurdistan in the Qajar and Pahlavi eras, which are kept in the Asif mansion of the Sanandaj court. Reading and analyzing the data in these documents play an irreplaceable role in reconstructing the social history of Kurdistan. Despite the quantitative and qualitative growth of the local history of Kurdistan during the Qajar era, research on the social history of this province has its own difficulties due to lack of resources. But without a doubt, re-reading and analyzing the documents of the Vaziri family, is the same discovery of new and desired sources by historians of social history. The present study uses a descriptive-analytical method and approach to social history to examine and explain the living conditions and work of the peasantries and leaders of Kurdistan in the Qajar and first Pahlavi eras as well as their interactions with each other and with the owners and the local government in the form of spheres of people relations with the people and the people with the government. Therefore, in the present article, first, the data and information are extracted from the text of 286 pages of the documents of the Vaziri family, and then their social classification is discussed.
