Mormonism in Britain began in the late 1830s with the arrival of American missionaries from the Church of Jesus Christ of Latter-day Saints. Not long afterward, thousands of British converts emigrated to Utah and became a kind of lifeblood for the early Mormon Church. England's North West, where Mormonism had its strongest presence, has become a place of profound significance to the church, yet its early importance to Mormonism has never been fully explored. Matthew Rasmussen's detailed account examines how Mormonism has changed and endured in Britain. After many British believers left for America, church membership in England fell so sharply that the movement in Britain seemed to be on the brink of collapse. Yet British Mormonism gradually rebuilt and continues today. How did this religious minority flourish when so many nineteenth-century revivalist movements did not? Rasmussen explains Mormonism’s inception, perpetuation, and maturation in Britain in a compelling case study of a “new religious movement” with staying power.
