This four-volume historical resource provides new opportunities for investigating the relationship between religion, literature and society in Britain and its imperial territories by making accessible a diverse selection of harder-to-find primary sources. These include religious fiction, poetry, essays, memoirs, sermons, travel writing, religious ephemera, unpublished notebooks and pamphlet literature. Spanning the long nineteenth century (c.1789–1914), the resource departs from older models of ‘the Victorian crisis of faith’ in order to open up new ways of conceptualising religion. Volume four on ‘Disbelief and New Beliefs’ explores the transformation of the religious landscape of Britain and its imperial territories during the nineteenth century as a result of key cultural and intellectual forces.
