This collection addresses many of the issues arising from the management of religious and cultural diversity in a multicultural society and refers to the complex relationship between the right to religious freedom and security. In recent decades, and particularly since September 2001, the right to religious freedom, which has hitherto been widely protected, has come up against a significant challenge in terms of security, or rather, in the subjectively and publicly perceived feelings of security. This book collects original theoretical, legal and comparative contributions addressing several implications for the right to freedom of religion or belief through the lens of security. It offers a new key to understanding how to manage the processes of integration of religious diversity in multifaith societies. Written by leading experts in the area, the work reveals the importance of avoiding simplistic conclusions and unfounded prejudices about religious freedom, and of limiting restrictive or repressive interventions to situations of genuine danger.The book will be an essential resource for researchers, academics and policy-makers working in the areas of Law and Religion, Human Rights Law and Security Studies.
