Freedom Summer was a 1964 voter registration project in Mississippi, part of a larger effort by civil rights groups such as the Congress of Racial Equality, and the Student Nonviolent Coordinating Committee. The Freedom Summer, consisted of black Mississippians and more than a thousand out-of-state, who faced constant abuse and harassment from Mississippi’s white population. The Ku Klux Klan, police and even state and local authorities carried out a systematic series of violent attacks; including beatings, false arrest and the murder of at least three civil rights activists.
