What does religion mean to modern Ireland and what is its recent social and political history? The Oxford Handbook of Religion in Modern Ireland provides in-depth analysis of the relationships between religion, society, politics, and everyday life on the island of Ireland from 1800 to the twenty-first century. Taking a chronological and all-island approach, it explores the complex and changing role of religion both before and after partition. The handbook's thirty-two chapters address long-standing historical and political debates about religion, identity, and politics, including religion's contributions to division and violence. They also offer perspectives on how religion interacts with education, the media, law, gender and sexuality, science, literature, and memory. Whilst providing insight into how everyday religious practices have intersected with the institutional structures of Catholicism and Protestantism, the book also examines the island's increasing religious diversity, including the rise of those with 'no religion'. Written by leading scholars in the field and emerging researchers with new perspectives, this is an authoritative and up-to-date volume that offers a wide-ranging and comprehensive survey of the enduring significance of religion on the island.
