Based on extensive in-depth interview research with young Europeans, this book reveals the root causes of radicalisation among European youth with different ethno-cultural and religious backgrounds.Drawing on interdisciplinary research and the voices of young people themselves, the book demonstrates that both nativist and Islamist trajectories emerge from overlapping experiences of inequality, insecurity, spatial marginalisation, and fractured futures. It explores the dynamics of radicalisation within European societies by examining the intersecting forces of globalisation, socio-economic deprivation, political deprivation, and spatial deprivation.It will appeal to scholars and students working on radicalisation, de-radicalisation, emotions, democracy and diversity management, minority and migration studies, globalisation, socio-economic deprivation, youth studies, and religious, nationalist, and culturalist ideologies. It will also be useful to policymakers and practitioners who work in the field of radicalisation and de-radicalisation.
