In the 1340s and 1350s, Mohammad Reza Pahlavi undertook developmentalist reforms in various areas of governance and tried to define an identity as a legitimate identity in each of these areas and persuade individuals (including students) to accept it. But this legitimate identity (the identity created by the Pahlavi government apparatus) was not welcomed by the students, the instrumental/intellectual elites of the society, and Mohammad Reza Shah's plans could not attract the consent of the students. Therefore, the main question of the article is: Why was legitimate identity (the identity constructed by the political system) rejected by students in the 1340s and 1350s? The paper hypothesized using the two theoretical constructs of Bourdieu's field/habitus and Castells's identity: The incompatibility of the legitimate identities of economic, academic, and political fields and the inconsistency of policies led to the rejection of legitimate identities by students. The findings of the article show that legitimate follow-up identity led students to formulate resistance identities. The article was written using the "how is it possible" explanatory method.
