Book excerpt: How might we best understand the relationship between the vibrant religious landscapes we see in many cities and contemporary urban social processes? Through case studies drawn from around the world, contributors explore the ways in which these processes interact in cities. This book argues that religious events – including rituals, processions, and festivals – are not only choreographies of sacred traditions, but they are also creative disruptions that reveal how urban cultural hierarchies are experienced and contested. Exposing the power dynamics behind these events, this book shows how performative uses of urban space serve to destabilize dominant genealogies and lineages around urban identities just as they lay claims to cultural supremacy or heritage. Through exploring the affective disruptions and political controversies caused by religious events, the contributors engage theoretical discussions in urban studies, the sociology of religion and the ethnography of ritual. This book is a significant contribution to understanding emerging patterns in contemporary religion and also for theories related to heritagization, eventization, and urbanization.
