Mormonism is the predominant religious tradition of the Latter Day Saint movement of Restorationist Christianity. Joseph Smith founded the movement in Western New York in the 1820s. During the 1830s and 1840s, Mormonism distinguished itself from traditional Protestantism. Mormonism represents the non-Protestant faith taught by Smith in the 1840s. After Smith's death in 1844, most Mormons followed Brigham Young on his westward journey to the area that became the Utah Territory, calling themselves The Church of Jesus Christ of Latter-day Saints (LDS Church). Variations not a part of the LDS Church include Mormon fundamentalism, which seeks to maintain practices and doctrines such as polygamy (which the LDS Church abandoned), and various other small independent denominations.
