Freedom Summer, also known as the Mississippi Summer Project, was a pivotal civil rights campaign in the US during the summer of 1964. Organized by civil rights organizations such as the Student Nonviolent Coordinating Committee (SNCC) and the Congress of Racial Equality (CORE), Freedom Summer aimed to increase Black voter registration in Mississippi, where African Americans faced intense racial discrimination and voter suppression.

During Freedom Summer, hundreds of mostly white college students from the North traveled to Mississippi to join local Black activists in registering Black voters, conducting freedom schools, and organizing community centers. The campaign faced violent repression from white supremacist groups and state authorities, resulting in the murder of three civil rights workers - James Chaney, Andrew Goodman, and Michael Schwerner.

Despite the challenges and violence, Freedom Summer succeeded in bringing national attention to the struggle for civil rights in the South, increasing Black voter registration, and laying the groundwork for the passage of the Voting Rights Act of 1965. The campaign highlighted the bravery and resilience of Black activists and their allies in the fight for racial justice and equality.
