Problem Statement: Political participation is one of the key factors in political and social transformations. The Islamic Revolution of Iran, as one of the most significant political events of the twentieth century, was rooted in widespread public participation. This participation played a critical role in the revolution itself and later in managing political crises and consolidating the Islamic Republic.

Main Question and Hypothesis: This research addresses the main question: "How did public political participation during the Islamic Revolution of Iran contribute to managing political crises?" It examines the hypothesis that public participation, guided by the leadership of Imam Khomeini (RA), successfully managed crises and institutionalized the new political system.

Methodology: This study adopts a descriptive-analytical approach and employs qualitative historical analysis. Data were collected from library resources and historical documents and analyzed using Charles Tilly's political mobilization theory. This methodology enables the examination of public political participation within a socio-historical framework.

Findings and Results: The findings reveal that during the Pahlavi era, political suppression and the restriction of freedoms led to informal mobilization. In the years leading up to the revolution, political participation escalated into a widespread movement that, under the leadership of Imam Khomeini (RA), culminated in the Islamic Revolution. After the revolution's victory, this participation continued through referenda, elections, and the Sacred Defense, contributing to the consolidation of the Islamic Republic, enhancing its legitimacy, and strengthening national cohesion. This participation established a lasting model for managing both domestic and international crises.
