This research sheds light on what has constituted and defined Iran’s post-revolutionary political identity and provides insights into its development with important socio-political implications. In order to understand the configuration and the evolution of post-revolutionary identity in Iran, we examined the Hajj Messages issued by the Supreme Leaders through content analysis within the framework of a threefold typological model of identity advanced by the authors: empiricistic, rationalistic, and idealistic. The clauses in Leader’s Hajj Messages are classified into the three categories based on the model. The results show that, in the post-revolutionary Iran, rationalism that inherits the doctrines of liberals’ anti-despotism, of leftists’ anti-colonialism, and Islamists’ return to Islam prevails. It is also observed that the post-revolutionary identity of Iran has empiricist factors and idealist factors, in the narrations of which the rituals of Hajj and the history of prophets are underscored respectively. This research also concerns ebbs and flows in the process of identity development in post-revolutionary Iran. Whilst rationalist factor keeps stable and is gradually strengthening its preponderance, idealism is ebbing away and empiricism is flowing in.
