The Latter-day Saint Movement, also known as Mormonism, 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 that he said was a record of ancient American prophets. The movement emphasizes the restoration of original Christianity and includes various beliefs about God, Jesus Christ, and the importance of modern-day prophets. The largest group within this movement is the Church of Jesus Christ of Latter-day Saints, which has millions of members worldwide. Other smaller groups, often referred to as "fundamentalist Mormons," may have different beliefs and practices. The movement is known for its emphasis on family, community service, and missionary work.
