This book probes the causes of and conditions for the preference of the members of the British-Bangladeshi community for a religion-based identity vis-a-vis ethnicity-based identity, and the influence of Islamists in shaping the discourse. The first book-length study to examine identity politics among the Bangladeshi diaspora delves into the micro-level dynamics, the internal and external factors and the role of the state and locates these within the broad framework of Muslim identity and Islamism, citizenship and the future of multiculturalism in Europe. Empirically grounded but enriched with in-depth analysis, and written in an accessible language this study is an invaluable reference for academics, policy makers and community activists. Students and researchers of British politics, ethnic/migration/diaspora studies, cultural studies, and political Islam will find the book extremely useful.
