Mormons are a religious and cultural group related to Mormonism, the principal branch of the Latter Day Saint movement of Restorationist Christianity, initiated by Joseph Smith in upstate New York during the 1820s. After Smith's death in 1844, the Mormons followed Brigham Young to what would become the Utah Territory. Today, most Mormons are understood to be members of The Church of Jesus Christ of Latter-day Saints. Some Mormons are also either independent or non-practicing. The center of Mormon cultural influence is in Utah, and North America has more Mormons than any other continent, though the majority of Mormons live outside the United States.
