Emmett Till and Mamie Till-Mobley National Monument includes several sites in Illinois and Mississippi. It preserves and protects historically important locations associated with the 1955 racially motivated murder of Emmett Till, an African American teenager. President Joseph Biden established the monument in 2023. 
In 1955, two men abducted and murdered 14-year-old Emmett Till in Mississippi for allegedly whistling at a white woman. At Till’s funeral in Chicago, his mother, Mamie Till, insisted that his coffin be left open in order to expose the brutality inflicted on her son. In the murder trial, an all-white jury acquitted (found not guilty) the two men responsible for the crime. After they were acquitted, the men admitted to torturing and murdering Till. Outrage over the Emmett Till case helped spark the civil rights movement of the 1950’s and 1960’s. 
The Emmett Till and Mamie Till-Mobley National Monument includes several sites. The Mississippi unit includes Grabball Landing in Glendora, Mississippi, where Emmett Till’s body was likely pulled from the Tallahatchie River. The first commemorative sign was installed in 2008, but vandals destroyed it and damaged several replacements over the next 10 years. A new bulletproof sign was installed in 2019. Because the site is now part of the national monument, it is a federal crime to vandalize the sign.
The national monument also includes the Tallahatchie County Second District Courthouse in Sumner, Mississippi. This courthouse was the location of the 1955 murder trial.
In Illinois, the monument includes the Roberts Temple Church of God in Christ, in Chicago. Mamie Till held her son’s funeral in this church. Thousands of people from across the United States attended.
