The White Horse Prophecy is the popular name of an influential but disputed version of a statement on the future of the Latter Day Saints (popularly called Mormons) and the United States.It was given by Edwin Rushton in about 1900, and supposedly made in 1843 by Joseph Smith, Jr., the founder of the Latter Day Saint movement. The Latter-day Saints, according to Rushton's version, would "go to the Rocky Mountains and... be a great and mighty people," associated in the prophecy's figurative language, with one of the biblical four Horsemen of the Apocalypse in the Book of Revelation.
