The enduring influence of religion in shaping postwar Europe. This volume examines the role of Christian churches in Europe during the often-overlooked postwar period (ca. 1918–ca. 1925), enriching our understanding of the enduring influence of religion in the aftermath of conflict. Taking a multinational, multidenominational, and multidimensional perspective, the essays explore the complex religious landscapes of postwar Europe, the resilience of ecclesiastical networks, and the transnational loyalties connecting Europe and North America. By highlighting the enduring vitality of faith and religious institutions, this study provides fresh insights into the evolving roles of churches, religious movements, and communities. Together, the essays shed light on the broader religious landscape of postwar Europe and provide an invaluable resource for understanding the lasting impact of religion in a transformed world.
