In the 1960s the civil rights movement attracted students to the South from all over the country to work on voter registration and integration. The intervention of people from outside the communities and threat of social change aroused fear and resentment among many whites. In June 1964, three civil rights workers disappeared in Neshoba County, Mississippi. They had been investigating the arson of a black church being used as a "Freedom School". Six weeks later, their bodies were found in a partially constructed dam near Philadelphia, Mississippi. James Chaney of Meridian, Mississippi, and Michael Schwerner and Andrew Goodman of New York City had been members of the Congress of Racial Equality. They had been dedicated to non-violent direct action against racial discrimination. The investigation also unearthed the bodies of numerous anonymous victims of past lynchings and murders.
