In this March-April 2013 issue, which Futuribles is devoting very largely to the social and political impact of religions, Franck Frégosi studies the place of Islam in European societies. After a short account of the history of the presence of the Muslim religion in Europe (from Arabic settlement in Spain in the Middle Ages to the Ottoman Empire and the migrations which followed the end of colonialism), Frégosi presents the various faces of Islam in Europe, which involves ethnic divides ensuing from the different regions of origin of European Muslims, a generation gap between the Islam practised by the younger generations and that of their elders, and ideological rifts. He then explores the three avenues of Islam’s current expression in Europe and the prospects for these: a minority Islam which favours a certain orthodoxy; a relatively radical, standardized Islam laying claim to universal applicability; and a trend towards secularization. Frégosi also stresses the limited character of the economic integration of Muslims in Europe and the difficulties they encounter in the area of employment –in France, for example, given the recurrent concern that manifestations of religion should be excluded from the public sphere and calls for the same to apply in the arena of private business. In his view, these various elements suggest that European Islam is in a mature phase, a phase of adaptation to the prevailing tradition of secularism in Western Europe.
