The murders of Chaney, Goodman, and Schwerner, also known as the Freedom Summer murders, the Mississippi civil rights workers' murders, or the Mississippi Burning murders, refers to events in which three activists were abducted and murdered in the city of Philadelphia, Mississippi, in June 1964 during the Civil Rights Movement. The victims were James Chaney from Meridian, Mississippi, and Andrew Goodman and Michael Schwerner from New York City. All three were associated with the Council of Federated Organizations (COFO) and its member organization, the Congress of Racial Equality (CORE). They had been working with the Freedom Summer campaign by attempting to register African Americans in Mississippi to vote. Since 1890 and through the turn of the century, southern states had systematically disenfranchised most black voters by discrimination in voter registration and voting.
