Post-First World War social reconstruction was grounded in the idea of community and brought leisure into social policy. Debate on leisure in post-war society was conducted within a broad mindset of welfare that embraced community, democracy, citizenship and education. This chapter reviews the application of new liberal theories of leisure to the creation of what Lloyd George promised as a country fit for heroes to live in. It explores the role of leisure in the creation of community and reviews the relationships between social service and leisure. The National Council of Social Service, formed in 1919, focused on the community rather than the individual and played a major supporting role in the implementation of social policy on leisure, notably the 1918 Education Act and the 1937 Physical Training and Recreation Act, both of which promoted voluntary action in leisure and set the foundations for the leisure policy of the welfare state.
