The Latter Day Saint Movement , ( Mormons ) have been persecuted since their founding in the 1830s . This persecution drove them from New York and Ohio to Missouri , where they continued to suffer violent attacks . In 1838 , Gov. Lilburn Boggs declared that Mormons had made war on the state of Missouri , and " must be treated as enemies , and must be exterminated or driven from the state " At least 10,000 were expelled from the State . In the most violent of the altercations at this time , the Haun 's mill Massacre , 17 were murdered by an anti-Mormon mob and 13 were wounded . The Extermination Order signed by Governor Boggs was not formally invalidated until 25 June 1976 , 137 years after being signed
