Joseph Smith Jr's Kevo

Smith left ambiguous or contradictory succession instructions that led to arguments and disagreements among the church's members and leadership, several of whom claimed rights to leadership.

An August 8, 1844 conference which established Young's leadership is the source of an oft-repeated legend. Multiple journal and eyewitness accounts from those who followed Young state that when Young spoke regarding the claims of succession by the Quorum of the Twelve Apostles, he appeared to look or sound like the late Smith. Although many of these accounts were written years after the event, there were contemporary records. Historian D. Michael Quinn wrote:
The Times and Seasons reported that just before the sustaining vote at the afternoon session of the August meeting, "every Saint could see that Elijah's mantle had truly fallen upon the 'Twelve.'" Although the church newspaper did not refer to Young specifically for the "mantle" experience, on 15 November 1844 Henry and Catharine Brooke wrote from Nauvoo that Young "favours Br Joseph, both in person, manner of speaking more than any person ever you saw, looks like another." Five days later Arza Hinckley referred to "Brigham Young on [w]hom the mantle of the prophet Joseph has fallen."
Most Latter Day Saints followed Young, but some aligned with other various people claiming to be Smith's successor. Some waited for Smith's son, Joseph Smith III, to assume leadership of the church despite his young age at the death of his father. The church had published a revelation in 1841 stating "I say unto my servant Joseph, In thee, and in thy seed, shall the kindred of the earth be blessed", and this was widely interpreted as endorsing the concept of Lineal Succession. Documentary evidence indicates also that Smith set apart his son as his successor at various private meetings and public gatherings, including Liberty and Nauvoo. Indeed, Brigham Young assured the bulk of Smith's followers as late as 1860 that young Joseph would eventually take his father's place. That year, the younger Smith became leader of what was to later be incorporated as the Reorganized Church of Jesus Christ of Latter Day Saints (now called the Community of Christ church) in the Midwest, made up of scattered church members not having journeyed west with Young, including Smith's widow Emma and two of Joseph III's brothers.

In addition, Smith's Vice Presidential running mate Sidney Rigdon formed the Church of Jesus Christ, headquartered in Greensburg, Pennsylvania with a few more congregations scattered throughout the area.

Many of these smaller groups were spread throughout the midwestern United States, especially in Independence, Missouri, and several remain viable as religious groups. Issues relating to the succession crisis are still the subject of discussion and debate.
