The Latter Day Saint Movement is a religious movement that began in the early 19th century in the United States. It was founded by Joseph Smith, who claimed to have received divine revelations and translated the Book of Mormon, a sacred text for its followers. The movement emphasizes the restoration of original Christianity and includes various denominations, the largest being the Church of Jesus Christ of Latter-day Saints. Members of the movement believe in modern-day prophets and continuing revelation from God. They practice unique rituals, such as baptism for the dead and temple ceremonies, which they believe are essential for salvation and eternal life. The movement has grown significantly and has millions of adherents worldwide.
