As the “war to end all wars” drew to a close in 1918, international boundaries had been redrawn, society had changed irrevocably, and communities across the world were experiencing loss on an unprecedented scale. In a Wales recently swept by religious revival, many people were sustained by their faith – but it was frequently challenged, too. A century later, on All Things Considered, Roy Jenkins and guests assess the impact of this epoch-changing conflict on faith in Wales and further afield. Joining Roy are: Dr Philip Jenkins, Distinguished Professor of History at Baylor University in Texas, who grew up in Port Talbot: one of his many books is ‘The Great and Holy War: How World War 1 changed religion for ever’; Dr Robin Barlow, author of ‘Wales and World War One’; Dr Robert Pope, Director of Studies in Church History and Doctrine at Westminster College Cambridge; and Dr Elin Jones, who was until recently responsible for the history curriculum in schools in Wales.
