Religious leader (1801–1877) who became leader of the Mormon Church in 1844 after its founder, Joseph Smith, was shot and killed by a mob of angry opponents. A charismatic and powerful leader, Young led the mass migration of Mormons to the Great Salt Lake Valley in Utah, establishing the church’s stronghold in that state. By the time of Young’s death, the Mormon population in Utah had reached 140,000, and the leader’s own legacy included twenty-seven wives and fifty-six children. Clear ink signature, “Brigham Young,” on a lightly lined off-white 3.5 x .75 slip affixed to a larger slip at the left and right edges. The larger slip bears the ink date February 1870 in another hand. Faint show-through of glue (near but not touching signature, and easily matted out) and tiny glue spot to first name, otherwise fine, bright condition. R&R COA.
