"Freedom Summer" refers to a significant campaign in 1964 aimed at increasing voter registration among African Americans in the southern United States, particularly in Mississippi. This initiative was organized by civil rights groups, including the Student Nonviolent Coordinating Committee (SNCC) and the Congress of Racial Equality (CORE). Volunteers, many of whom were college students, traveled to Mississippi to help register voters and establish freedom schools to educate the local population about their rights. The campaign faced intense opposition, including violence and intimidation from local white residents and law enforcement. The disappearance and murder of three civil rights workers—James Chaney, Andrew Goodman, and Michael Schwerner—highlighted the dangers faced by those involved. Despite these challenges, Freedom Summer played a crucial role in raising awareness about civil rights issues and led to the eventual passage of the Voting Rights Act of 1965.
