The Revolution of 1979 in Iran took place with the participation of various intellectual and political spectrums. The militant Muslim movement led by Habibollah Peyman was one of these movements with an identity at the intersection of Islamic, monotheistic, and socialist ideas. This article, relying on the descriptive-analytical method and intentionalist hermeneutics of Quentin Skinner, explains the approach of this movement towards the leadership of Ayatollah Khomeini and the revolution. The main hypothesis of the article is that the militant Muslim movement adopted a “strategic convergence and teleological divergence” position; meaning that during the stage of overthrowing the Shah’s regime, with a correct analysis of the circumstances, it accepted the leadership of Ayatollah Khomeini as a practical solution to achieve a common goal (strategic convergence). However, based on its socialist-Monotheism ideology, this movement had a different vision for the future of society based on social revolution and public ownership, which was fundamentally different from the emerging model of the Islamic Republic (teleological divergence). The research findings show that this approach initially led to cooperation and then to the marginalization of this movement after the victory of the revolution, and is a clear example of the complexity of revolutionary coalitions and divergence over the definition of the ideals of the revolution.
