After 17 months of travel, Brigham Young leads 148 Mormon pioneers into Salt Lake Valley, resulting in the establishment of Salt Lake City.

Salt Lake Valley is a 500-square-mile (1,300 km2) valley in Salt Lake County in the north-central portion of the U.S. state of Utah. It contains Salt Lake City and many of its suburbs, notably Murray, Sandy, South Jordan, West Jordan, and West Valley City; its total population is 1,029,655 as of 2010. Brigham Young said, "this is the right place," when he and his fellow Mormon settlers moved into Utah after being driven out of several states.

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 which would later become the University of Utah and Brigham Young University. A polygamist, Young had at least 55 wives and 56 children. He instituted a ban prohibiting conferring the priesthood on men of black African descent, and led the church in the Utah War against the United States.
