Killing of Joseph Smith
Joseph Smith, the founder and leader of the Latter Day Saint movement, and his brother, Hyrum Smith, were killed by a mob in Carthage, Illinois, United States, on June 27, 1844, while awaiting trial in the town jail on charges of treason. As a result of the 1838 Mormon War and a state executive order by Missouri Governor Lilburn Boggs, a large group of Mormons, including Smith and his brother, had to flee Missouri.
