The document discusses the history of the Mormon religion and its followers, the Mormons. It describes how Joseph Smith founded the religion after claiming to see visions of angels and golden plates. The Mormons faced persecution for their beliefs in polygamy and political ambitions, leading them to be driven from Ohio, Missouri, and Illinois. Brigham Young then led the Mormons westward to Salt Lake Valley in 1847 to escape violence and find a safe place to practice their faith. Through cooperation, leadership, and self-sufficiency, the Mormons were able to survive and establish Salt Lake City despite hardships and conflicts with the U.S. government over their sovereignty.
