Campaigns for moral reform were a recurrent and distinctive feature of public life in later Georgian and Victorian England. Antislavery, temperance, charity organisation, cruelty prevention, ‘social purity’ advocates and more – all promoted their causes through the mobilisation of citizen volunteer support. This book sets out to explore the world of these volunteer networks, their foci of concern, their patterns of recruitment, their methods of operation, and the responses they aroused. In its exploration of this culture of self-consciously altruistic associational effort, the book provides the first systematic survey of moral reform movements as a distinct tradition of citizen action over the period, as well as casting light on the formation of a middle-class culture torn, in this stage of economic and political nation-building, between acceptance of a market-organised society and unease about the cultural consequences of doing so. This is a revelatory book that is both compelling and accessible.
