A survey of Welsh Christianity from its origins in Roman Britain to the present. Christianity has played an enormous role in the history of Wales and in the defining and shaping of Welsh identity over the past two thousand years. Biblical place names, an urban and rural landscape littered with churches, chapels, crosses, and sacred sites, a bardic and literary tradition deeply imbued with Christian themes in both the Welsh and English languages, and the songs sung by tens of thousands of rugby fans all hint at a Christian presence that was once universal. Yet for many people in contemporary Wales, the story of the development of Christianity in the country remains little known. Aimed at the general reader, this is the first single-volume history of Welsh Christianity from its origins in Roman Britain to the present. Drawing on the expertise of four leading historians of the Welsh Christian tradition, it offers a succinct, clear, and accessible account of the development of Christianity in Wales in its Catholic, Protestant, and Nonconformist forms and will be the perfect introduction to the subject.
