Identity and national identity are regarded as one main problem in political sociology. Nowadays, political scholars, following fast changes of the age, have spoken of the problem in political literature much. Among the ways of studying the problem in Iran is the discourse of politico-intellectual currents active in politico-social of Iranian society. Studying Islamist current (as the main current taken the form of hegemony at appearance of IR) as national identity may prepare a new way for directing studies of IR. Using the method of discoursive analysis and choosing Ali Shari`ti and Hjjat ul-Islam Seyyed Ali Khamenei as two deputies of the current, the paper has intended to explain the what of national identity of the current before and after IR. It was, yet, presupposed that the deputies had main components and concepts in common to a large extent.
