At the beginning of the 2010s, several Arab countries seemed about to follow the model of Turkey, with an electoral victory of Islamist parties in a context of democratization. A decade later, Turkish akp has turned authoritarian, and the Moroccan and Tunisian Islamist parties have lost both access to governmental office and a large part of their electoral appeal. In this context, lessons can be learned from the early failed democratic experience in Algeria (1989–1992), and from the evolution of its Islamist movements since then. From these four case studies, the contributors of this issue investigate the notions of moderation and inclusion, and their interrelations. Their articles build on the current trends within literature by taking into account the variety of Islamist movements, and their incorporation within different national trajectories. These articles contribute to the academic discussion by bringing new facts and ideas regarding this topic of inclusion-moderation.
