An all-white jury in Mississippi finds Roy Bryant and J. W. Milam not guilty in the torture-murder of 14-year-old African American boy Emmett Till.

Mississippi is a state in the Southeastern and Deep South regions of the United States. It borders Tennessee to the north, Alabama to the east, the Gulf of Mexico to the south, Louisiana to the southwest, and Arkansas to the northwest. Mississippi's western boundary is largely defined by the Mississippi River, or its historical course. Mississippi is the 32nd largest by area and 35th-most populous of the 50 U.S. states and has the lowest per-capita income. Jackson is both the state's capital and largest city. Greater Jackson is the state's most populous metropolitan area, with a population of 591,978 in 2020. Other major cities include Gulfport, Southaven, Hattiesburg, Biloxi, Olive Branch, Tupelo, Meridian, and Greenville.

Emmett Louis Till was an African American youth, who was 14 years old when he was abducted and lynched in Mississippi in 1955 after being accused of offending a white woman, Carolyn Bryant, in her family's grocery store. The brutality of his murder and the acquittal of his killers drew attention to the long history of violent persecution of African Americans in the United States. Till posthumously became an icon of the civil rights movement.
