While French laïcité is often considered something fixed, its daily deployment is rather messy. What might we learn if we study the governance of religion from a dynamic bottom-up perspective? Using an ethnographic approach, this book examines everyday secularism in the making. How do city actors understand, frame and govern religious diversity? Which local factors play a role in those processes? In Urban Secularism: Negotiating Religious Diversity in Europe, Julia Martínez-Ariño brings the reader closer to the entrails of laïcité. She provides detailed accounts of the ways religious groups, city officials, municipal employees, secularist actors and other civil-society organisations negotiate concrete public expressions of religion.
