Genealogy and Historical and Geographical Origin of Gachgaran Descendants from Mamasani Tribe

The entry of the Mamasani tribe into the geographical space of Shulistan in the Safavid period brought the social and political demarcations of the tribes within the framework of separate geographical territories. Influenced by such demarcations, Mamasani human beings also settled in different territories. It seems that such human beings in each of these domains have their own ancestry background, so that their genealogy and historical and geographical origin play a role in how their social structure is arranged. In this regard, the human settlements of Mamasani County are the residence of several children who have formed its cultural and social context together. In this context, Gachgaran rural settlement in the central part of Mamasani city and First Baksh village has a significant manpower and population. The research is based on the question of what historical and geographical origin of the descendants of Gachgaran in the Mamasani tribe? The research method is descriptive-analytical in nature and data related to 55 Descendants were collected by both library and field methods. The results showed that 55 children settled in Gachgaran settlement have different descent and historical and geographical origin (different spatial origin and different descent and identity). The worldview and socio-political attitude of these children also includes aspects of general similarity and partial differentiation that have influenced their social and political action.
