The German Protestant Kirchentag (Church Convention), founded four years after the end of the Second World War, was an influential movement and discursive platform in the process of rebuilding Protestantism in divided Germany and is still influential today. The volume collects the interdisciplinary contributions of the academic conference at Alfried Krupp Institute for Advanced Study in Greifswald on the occasion of the 75th anniversary of the Kirchentag. It provides an introduction to the history of this successful gathering of lay protestants and shows how the search for peace is a central and recurring subject during all periods of discussion platforms and working groups at the Church Convention in both German states. Against the backdrop of selected debates in Peace Ethics after 1945 and current challenges of violence and war, injustice and climate change, the volume investigates past deliberations, arguments and societal discussions at the Kirchentag up to German reunification and ethically and hermeneutically discusses current questions of peace.
