David Ceri Jones’s landmark study situates the Welsh Methodist Revival within the context of the international evangelical community that thrived, particularly between 1735 and 1750, and that spanned many parts of Europe and the American colonies. The Welsh revival was one constituent element of this much wider pan-Protestant awakening. This survey focuses on the relationship of the Welsh revival with its various sister awakenings in England, Scotland, Ireland, parts of France, Germany and the American colonies. Analysing the means by which Methodists in Wales communicated with their fellow evangelicals, it traces some of the ways in which the Welsh Methodists contributed to the wider evangelical enterprise and argues that the Methodist Revival actually represents the birth of Evangelicalism in Wales. ‘A Glorious Work in the World’: Welsh Methodism and the International Evangelical Revival, 1735-1750 will be essential reading for anyone interested in the history of Methodism and the Evangelical Revival, as well as those interested in the broader questions of literacy, popular religion, national identity and the eighteenth-century British Atlantic world more generally.
