Аннотация:Disputes over the outcome of the June 2009 presidential election in Iran rapidly developed into a contest about the legitimacy of the Islamic state. Far from being a dispute between religious and non-religious forces, the main protagonists in the conflict represented divergent articulations of state–religion relations within an Islamic context. In contrast to the authoritarian legitimisation of an Islamic state, the Islamic reformation discourse is based on secular-democratic articulations of state–religion relations. This article focuses on the ideas of four leading Iranian religious scholars who advocate a secular-democratic conceptualisation of state authority. Disputing the religious validity of divine sovereignty, they promote the principle of popular sovereignty based on Islamic sources and methods. This reformist conceptualisation is rooted in the notion that Islam and the secular-democratic state are complementary.
