Early Mormon history is marked by many instances of violence, which have helped to shape the church's views on violence. The first significant instance occurred in Missouri. Mormons who lived there tended to vote as a bloc, which often lead to the unseating of the local political leadership. Differences culminated in hostilities and the eventual issuing of an executive order (often called the Extermination Order) by Missouri governor Lilburn Boggs declaring, "the Mormons must be treated as enemies, and must be exterminated or driven from the State." Three days later, a militia unit attacked a Mormon settlement at Haun's Mill, resulting in the death of 18 Mormons and no militiamen. The Extermination Order was not formally rescinded until 1976.
