Freedom Riders were civil rights activists who rode interstate buses into the segregated Southern United States in 1961 and subsequent years to challenge the non-enforcement of the United States Supreme Court decisions Morgan v. Virginia (1946) and Boynton v. Virginia (1960), which ruled that segregated public buses were unconstitutional. The Southern states had ignored the rulings and the federal government did nothing to enforce them. The first Freedom Ride left Washington, D.C., on May 4, 1961, and was scheduled to arrive in New Orleans on May 17.

The Student Nonviolent Coordinating Committee was the principal channel of student commitment in the United States to the civil rights movement during the 1960s. Emerging in 1960 from the student-led sit-ins at segregated lunch counters in Greensboro, North Carolina, and Nashville, Tennessee, the Committee sought to coordinate and assist direct-action challenges to the civic segregation and political exclusion of African Americans. From 1962, with the support of the Voter Education Project, SNCC committed to the registration and mobilization of black voters in the Deep South. Affiliates such as the Mississippi Freedom Democratic Party and the Lowndes County Freedom Organization in Alabama also worked to increase the pressure on federal and state government to enforce constitutional protections.
