The religious movement popularly known as Mormonism encompasses several denominations and sects, the largest of which is the Church of Jesus Christ of Latter-day Saints, which is headquartered in Salt Lake City, Utah, and had a worldwide membership of about twelve million in 2003. The second largest organization is the Community of Christ (formerly known as the Reorganized Church of Jesus Christ of Latter Day Saints) with headquarters in Independence, Missouri, and a membership of about 250,000. Perhaps the smallest of numerous Mormon splinter groups is the Church of Jesus Christ of Latter Day Saints (Strangite) in Burlington, Wisconsin—composed of followers of James T. Strang (1813–1856)—with about two hundred members. All of these churches trace their origins to founder Joseph Smith Jr. (1805–1844).
