Understanding the concept of religious freedom is essential for policy writers, faith practitioners and more importantly anyone eager to engage with the faith community. An effective faith engagement and implementation strategy must take account of the legal development in the field of religious discrimination. This author takes the readers on a journey that provides an explanatory legal etymology of the concept of religious discrimination within the international scene and the United Kingdom before the arrival of HRA 1998. This book also examines protections available in other common law countries like USA, Australia, Nigeria and South Africa.
