This article addresses democratic construction in Islamic societies throughout the Algerian experience. Its main conclusions can be summarized as follows. First, in all Muslim societies, there exists an Islamicist utopia that stands as an obstacle not only to democracy but also to political modernity. Until now, this utopia has been contained only by repression that finally impedes the democratization. Second, Islam presents itself as a public religion that participates in the legitimization of political power. The democratic ideology, however, is compatible with religion to the extent that it is lived as a private concern. Finally, the Islamicist utopia and the public aspect of Islam aim at maintaining society's communal structures. They refuse to make the singularity of the political arena independent and reject differentiation through politics within a society that claims to be fraternal.
