 The economic, political, and religious dominance of the Mormons (Smith was mayor of the city and commander of the local militia, the Nauvoo Legion) inspired mobs to attack the city, and Smith was arrested for ordering the destruction of an anti-Mormon newspaper, the "Nauvoo Expositor", although he acted with the consent of the city council.He was imprisoned, along with his brother Hyrum Smith, at Carthage Jail, where they were attacked by a mob and murdered.After a succession crisis, most of the Mormons united under Brigham Young, who organized an evacuation from Nauvoo and from the United States itself after the federal government refused to protect the Mormons.
