Mississippi lawmakers are honoring civil rights activists as the 50th anniversary of Freedom Summer approaches.
Hundreds of college students converged on the state in 1964 to help local people challenge a strictly segregated society. They registered black voters and established schools.
Some of the volunteers were threatened or beaten. Three of them, Michael Schwerner, James Chaney and Andrew Goodman, were killed in what became known as the "Mississippi Burning" case.
Lawmakers have adopted a resolution honoring Freedom Summer participants, who are holding events in late June to mark the anniversary.
Civil rights veteran Hollis Watkins told senators Wednesday: "We've come a long way, but we still have a long way to go." Senators gave Watkins and others a standing ovation.
