Brigham Young (; June 1, 1801 – August 29, 1877) was an American religious leader and politician. He was the second president of the Church of Jesus Christ of Latter-day Saints (LDS Church), from 1847 until his death in 1877. During his time as church president, Young led his followers, the Mormon pioneers, west from Nauvoo, Illinois, to the Salt Lake Valley. He founded Salt Lake City and served as the first governor of the Utah Territory. Young also worked to establish the learning institutions that would later become the University of Utah and Brigham Young University. A polygamist, Young had at least 56 wives and 57 children. He formalized the prohibition of black men attaining priesthood, and led the church in the Utah War against the United States.
