This topical collection of articles by leading scholars confronts us with a complex and diverse post-modern phenomenon in the European context … it helps make sense of both the debates around the role of the media, Islamophobia, social and economic exclusion, crises of Muslim masculinity, gender and intergenerational conflicts, the impact of global political developments, and questions of identity in fuelling radical 'Islamism', and of the more urgent reflections on terrorism and violence post-7/7. Readers will be left in little doubt about the challenge that Islamic political radicalism poses in twenty-first century Europe to both Muslims and non-Muslims.
