This research presents a comparative analysis regarding the influence of religion as a key component of national identity on behavioral patterns in Iran's foreign policy across two distinct periods: that of Pahlavi II and the Islamic Republic. The significance of examining religion arises from its impact on national interest formulation within constructivist frameworks, where identity constructs play a pivotal role. The primary objective of this study is to elucidate how recognizing religion's position as an identity factor can enhance our understanding of behavioral patterns in Iran's foreign policy. Addressing the inquiry into religion's influence on these patterns during both eras, this paper posits that while religion was one of many influential factors in Pahlavi II's foreign policy landscape, it did not substantially integrate into national identity or affect foreign policy decisions at that time. Conversely, within the Islamic Republic framework, religion emerges as a fundamental ideology and an independent variable that shapes foreign policy behavior. The research findings ultimately reveal that during Pahlavi II’s era, national interests were defined through the lens of modern state identity, whereas Shia ideology became central to shaping foreign policy identity in the Islamic Republic. Consequently, religion has demonstrated a significant direct impact on behavioral patterns within this political context.
