Demonstrates the vital role Sunday schools played in forming and sustaining faith before, during, and after the First World War for British populations both at home and abroad.Sunday schools were an important part of the religious landscape of twentieth-century Britain and they were widely attended by much of the British population. The Sunday School Movement in Britain argues that the schools played a vital role in forming and sustaining the faith of those who lived and served during the First World War. Moreover, the volume contends that the conflict did not cause the schools to decline and proposes that decline instead set in much earlier in the twentieth century. The book also questions the perception that the schools were ineffective tools of religious socialisation and examines the continued attempts of the Sunday school movement to professionalise and improve their efforts. Thus, the involvement of the movement with the World's Sunday School Association is revealed to be part of the wider developing international ecumenical community during the twentieth century.Drawing together under-utilised material from archives and newspapers in national and local collections, The Sunday School Movement in Britain presents a history of the schools demonstrating their lasting significance in the religious life of the nation and, by extension, the enduring importance of Christianity in Britain during the first half of the twentieth century.
