Host Martin Tanner highly recommends a new, historically accurate, highest quality LDS film Six Days in August, about the succession issue, who would lead the Church after Joseph Smith was murdered on June 27th, 1844.  For several months it was unclear who would lead the Church.  The Council of the Twelve Apostles and its president, Brigham Young, promised to continue to lead the Church just as Joseph Smith had been planning.  Sidney Rigdon, another possible successor, would have kept the Church in Nauvoo or in the mid-West.  James Strang claimed to be a successor prophet and wanted to lead the Church.  Emma wanted Joseph Smith, III, to be the next president, but he was only 11 years old.  In a Church assembly in August 1844, Sidney Rigdon spoke and convinced many he should lead, but them Brigham Young spoke, and according to the diaries of over 120 people who were at the assembly, Brigham Young appeared to appear as Joseph Smith, or sounded like Joseph Smith, which was taken as a sign from God. The Church members overwhelmingly voted for Brigham and the Apostles to lead the Church.
