Since the mid-nineteenth century, only a modicum of attention has been given to the amazing success of the Latter-day Saint missionary effort in Wales. This book provides valuable historical context and publication information about The Church of Jesus Christ of Latter-day Saints in the Principality of Wales during the 1840s and 1850s—the Church’s beginnings, its growth, and its progress amid the constant opposition and allegations from other religious persons and organizations that felt threatened by the doctrine and proselytizing of Latter-day Saint missionaries.
