The social classes of the antebellum South included the planter elite, small planters, businessmen or the middle class, yeomen farmers, poor whites, free blacks, and slaves. The planter elite, small planters, and sometimes businessmen and yeomen farmers owned slaves who performed much of the work for them, although each group except the planter elite often worked with slaves in the fields or at other hard labor. Small planters, businessmen, yeomen farmers, and poor whites often had dreams of increasing their wealth so they could join the planter elite. Poor whites were hindered from getting agricultural work because of slavery yet enjoyed white privilege, although slaves were often better nourished and clothed than poor whites. Poor whites and slaves traded goods, and slaves labeled poor whites as "poor white trash." Free blacks and slaves created an African American community in spite of differences in freedom. Slaves often resisted white society by rebelling and creating a distinct slave community and religion outside of the control of southern whites. The Missouri Mormon War took place in 1838 in the northwest Missouri counties of Caldwell and Daviess and included conflict between the Mormons and Missourians over land, politics, economics, and religion. The extermination order was issued on October 27, 1838, by Missouri governor Lilburn Boggs, who claimed Mormons should be driven from the state or exterminated because of the threat this group posed to public safety. Three days later the Mormon settlement of Haun's Mill was attacked by a Missouri militia, which massacred seventeen Mormon men and boys. The Mormons eventually left the state of Missouri but faced similar persecution in Nauvoo, Illinois. Joseph Smith and his brother were killed in a Carthage, Illinois, jail in 1844.
