Church of Jesus Christ of the Children of Zion

Rigdonite is a name given to members of the Latter Day Saint movement who accept Sidney Rigdon as the successor in the church presidency to movement founder, Joseph Smith. The early history of the Rigdonite movement is shared with the history of the Latter Day Saint movement, but as of the 1844 succession crisis becomes distinct. Sidney Rigdon and other church leaders, including Brigham Young and James J. Strang, presented themselves as leaders of the movement and established rival church organizations. Rigdon's group was initially headquartered in Pittsburgh, Pennsylvania. It was known at one point as the Church of Jesus Christ of the Children of Zion, and its adherents are referred to as Rigdonites, or sometimes "Pennsylvania Latter Day Saints" or "Pennsylvania Mormons." The only surviving organization that traces its succession back to Rigdon's organization is The Church of Jesus Christ, founded by a group of Rigdon's followers led by William Bickerton.

Sidney Rigdon, who had been the first counselor in the first presidency under Joseph Smith, claimed to have received a vision, after the death of Joseph Smith, sustaining him as the leader of the Church. Although Joseph Smith taught that after the president in a presidency is released or dies the presidency no longer exists, Rigdon overlooked this teaching and returned to attempt to convince the other saints that he was to be the leader of the church. Unconvinced, because the other members were familiar with Smith's teachings, Brigham Young presented the doctrine taught by Smith that aside from the first presidency, the quorum of the twelve apostles was the governing body of the church. Most Latter Day Saints followed Young as a result.
