The Latter Day Saint movement (also called the LDS movement, LDS restorationist movement, or Smith–Rigdon movement) is the collection of independent church groups that trace their origins to a Christian Restorationist movement founded by Joseph Smith in the late 1820s.
Collectively, these churches have almost 18 million nominal members, including over 17 million belonging to the Church of Jesus Christ of Latter-day Saints (LDS Church), 250,000 in Community of Christ, and several other denominations with memberships generally ranging in the thousands of members. The predominant theology of the churches in the movement is Mormonism, which sees itself as restoring again on Earth the early Christian church; their members are most commonly known as Mormons. An additional doctrine of the church allows for prophets to receive and publish modern-day revelations.
