Taylor, shot five times, was with Joseph and Hyrum Smith when they were assassinated by a mob in Carthage jail. He was thereafter known by some as a "living martyr." In 1847, with Parley P. Pratt, Taylor led 1,500 pioneers from Winter Quarters to Salt Lake Valley, where he helped found Utah's sugar-manufacturing industry in 1852. A naturalized American citizen, he was elected to the territorial legislature from 1854 to 1876 and served as territorial superintendent of schools in 1877. Presiding over the Mormon Church as its third president from 1877 to 1887, he approved the Primary Association for children and founded Zion's Central Board of Trade, an economic cooperative organization (1878). During the church's Jubilee Year celebration in 1880, he reorganized the First Presidency, forgave debts owed to the Perpetual Emigrating Company by the poor, and canonized the Pearl of Great Price as scripture. The Assembly Hall on Temple Square (1882) and the Logan Temple (1884) were completed and dedicated under his direction.
