Latter-day Saints

The Latter Day Saint movement (also called the LDS movement, LDS restorationist movement, or Smith–Rigdon movement) is the collection of independent church groups that trace their origins to a Christian primitivist movement founded by Joseph Smith in the late 1820s. Collectively, these churches have over 15 million members. The vast majority of adherents belong to The Church of Jesus Christ of Latter-day Saints (LDS Church), with their predominant theology being Mormonism. The LDS Church self-identifies as Christian. A minority of Latter Day Saint adherents, such as members of the Community of Christ, believe in traditional Protestant theology, and have distanced themselves from some of the distinctive doctrines of Mormonism. Other groups include the Remnant Church of Jesus Christ of Latter Day Saints, which supports lineal succession of leadership from Smith's descendants, and the more controversial Fundamentalist Church of Jesus Christ of Latter-Day Saints, which defends the practice of polygamy.

The movement began in western New York during the Second Great Awakening when Smith said that he received visions revealing a new sacred text, the Book of Mormon, which he published in 1830 as a complement to the Bible. Based on the teachings of this book and other revelations, Smith founded a Christian primitivist church, called the "Church of Christ". The Book of Mormon attracted hundreds of early followers, who later became known as "Mormons", "Latter Day Saints", or just "Saints." In 1831, Smith moved the church headquarters to Kirtland, Ohio, and in 1838 changed its name to the "Church of Jesus Christ of Latter Day Saints."
