Joseph Smith Jr. (December 23, 1805 – June 27, 1844) was an American religious and political leader and the founder of Mormonism and the Latter Day Saint movement. Publishing the Book of Mormon at the age of 24, Smith attracted tens of thousands of followers by the time of his death fourteen years later. The religious movement he founded is followed by millions of global adherents and several churches, the largest of which is the Church of Jesus Christ of Latter-day Saints (LDS Church).
Born in Sharon, Vermont, Smith moved with his family to Western New York amid hardships following a series of crop failures in 1816. Living in an area of intense religious revivalism during the Second Great Awakening, Smith reported experiencing a series of visions. The first of these was in 1820, when he saw "two personages" (whom he eventually described as God the Father and Jesus Christ). In 1823, he said he was visited by an angel who directed him to a buried book of golden plates inscribed with a Judeo-Christian history of an ancient American civilization. In 1830, Smith published the Book of Mormon, which he described as an English translation of those plates.
