Militarism in the texts and literature of the country is generally perceived with hostility, militancy, or militocracy. While the ideology of militarism during the First Pahlavi era, like Germany, Italy, and Japan before World War II, was accompanied by nationalist ideas, forming the theoretical basis for societal changes. Furthermore, under the influence of military ideology in society and general culture, militaristic approaches in resolving internal conflicts, the presence of a large army, high military costs, and the superiority of the military over civil society were legitimized. The paper considers the imposition of militaristic values on society as its main issue and focuses on the role and central position of Reza Khan Sardar Sepah (Minister of War) in changing the constitutional system, emphasizing his strategy in utilizing this phenomenon. The research, for analyzing the collected data from documents and newspapers, adopts a hermeneutic approach to understand empathetically with the actor and uses militarized societies as a model. The research findings indicate that Reza Khan's strategy in using militarism as a social imperative militarized the general culture by redefining society based on militaristic values. To substantiate the presented claim, two areas, education, and media, are specifically examined.
