 After Smith was killed 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).Other sects include Mormon fundamentalism, which seeks to maintain practices and doctrines such as polygamy, and other small independent denominations.The second-largest Latter Day Saint denomination, the Reorganized Church of Jesus Christ of Latter-day Saints, since 2001 called the Community of Christ, does not describe itself as "Mormon", but follows a Trinitarian Christian restorationist theology, and considers itself Restorationist in terms of Latter Day Saint doctrine.
