Discourses, as structured sets of mental elements, construct diverse forms of power delegation to political-regional institutions, manifesting within the historical context of territory. However, the stabilization and continuity of discursive legitimacy requires interpreters who can theorize about the coherence of relationships between symbols and social forces in describing this legitimacy and reject the alienation forces. during the Qajar era (1796-1925), prior to the Constitutional Revolution of 1906, a quasi-federal model of governance emerged, characterized by the delegation of authority to socio-regional force which was unprecedented. During this period, the clergy, as one of the most important social forces, was able to legitimize the continuity of this discourse by establishing the necessary cognitive framework for it under the Islamic jurisprudence. in this research, within the framework of Foucault's power/knowledge relationship, has been attempted to examine how this social class acted to legitimize quasi-federal governance before the Constitutional Revolution. Research findings indicate that the configuration of the knowledge/power system under governance quasi-federal led to a prevailing belief in the necessity of the Islamic jurisprudence on social issues to solidify the foundations of this discourse. moreover, the economic ties between the clergy and urban merchants, artisans, and rural landowners led to Shiite jurists supporting their interests and stabilized the socio-spatial distribution of power. Moreover, the absence of a standing army during this period meant that Qajar kings needed the Shiite jurists order to mobilize tribes and other social classes during times of war.
