Book excerpt: Repositioning mosques as social, cultural and political spaces, this book provides new insights on key contemporary debates, the religious identity of Britain, secularisation, the far-right and terrorism, and gender equality. Exploring the story of the British mosque, from house conversions to grand works of architecture, and the role they play in public life, Abdul-Azim Ahmed details the establishment of early mosques during the era of Empire, and the rapid growth in the years following the Second World War. Ahmed takes a sociological approach to this study, drawing on fieldwork and ethnographic case-studies, alongside reviews of databases and historical documents to provide perspectives on the British mosque from the congregants themselves. The Muslim congregation, a poorly understood and often overlooked dimension of religion in Britain, is examined, and issues of diversity, denomination, sacredness, and society are explored.
