More than a year after the start of the Tunisian and Egyptian revolts, the question of how political Islam will return to regional politics is still open. This article explores the differences between the AKP’s Turkish model and the Tunisian al-Nahda movement. The Tunisian and the Turkish case studies are examined and compared on three levels. First of all the historical and structural contexts of the two countries and the relationship between the state and Islam are taken into account. Secondly the two models of political Islam that have developed in Tunisia and Turkey are analyzed. Finally, the two different views of the social, political and economic life proposed by al-Nahda in Tunisia and by the AKP in Turkey are compared. By examining the structural differences between these two contexts, and consequently by looking at the two distinctive ways of understanding Islam in public life, the article will also demonstrate how and why the “Turkish model”, as represented by the AKP, cannot be applied to Tunisia, although the al-Nahda has itself embarked on a process of “de-radicalization.”
