Mormonism is the predominant religious tradition of the Latter Day Saint movement. This movement was founded by Joseph Smith, Jr. beginning in the 1820s as a form of Christian primitivism. During the 1830s and 1840s, Mormonism gradually distinguished itself from traditional Protestantism. Mormonism today represents the new, non-Protestant faith taught by Smith in the 1840s, while its branches include Mormon fundamentalism, which seeks to maintain practices and doctrines such as polygamy that were discontinued by the LDS Church, and various other small independent denominations. Learn more about Mormons, both fundamentalist and mainstream, their beliefs and history in the following pages.
