Backstory and Context
Joseph Smith never had the opportunity to turn his utopian vision into a reality, however, as an anti-Mormon mob killed Smith in 1844. As a result of his death, church leadership fell to Brigham Young, who led LDS members to the Salt Lake Valley; they established Salt Lake City in 1847.
