Meredith Mississippi March Against Fear came through Grenada via Highway 51 on June 15, 1966. A voter rally was held afterward in the town square. That night, Dr. Martin Luther King, Jr. gave a speech. About 1,300 people were registered to vote after the rally, but it is estimated that 700 of those people would not be allowed to vote because county officials did not tell them that voters also had to register at City Hall. Shortly after the march, the Grenada County Freedom Movement (GCFM) was created and it affiliated with the SCLC.
