this study examines the changes in social and economic capital of clergy class from the Safavid period to after the victory of Islamic Revolution in Iran. The goal is to explain how the axis of capital of this class shifted from cultural and social arena to the economic and political arena after Revolution. The question is: What changes have occurred in social and economic capital of the clergy class after the Islamic Revolution in Iran? The hypothesis is that after the revolution, holding executive positions and controlling government resources strengthened the economic and political capital of the clergy, but challenged the relative weight of traditional cultural capital and some of the social legitimacy in the context of changing functions. The research method is descriptive-analytical, and the data were collected through documentary and library studies and analyzed using Bourdieu's theory. The findings show that before the revolution, clergy's capital was informal and spontaneous in nature, based on social influence networks, popular support, and independent financial mechanisms. But after the revolution, with institutionalization of their role and entry into governance structure, the clergy became a powerful actor in the formal arena of power, benefiting from state and economic resources. This shift from independence to structural integration increased influence and executive capacities of clergy. However, the emphasis on executive and political functions has overshadowed attention to traditional missionary and guiding missions, creating challenges in terms of public expectations and the need to redefine their social authority in the face of new political environment.
