In 1963, representatives of civil rights organizations such as the Student Non-Violent Coordinating Committee (SNCC) and the Dallas County Voter's League (DCVL) organized Black residents of Selma, Alabama, to challenge discriminatory voter registration practices.
The registrars intentionally slowed down the proceedings, limiting registration to only a few people every hour and ensuring that only a small handful of those waiting in line would be able to register. Sheriff Clark, his deputies, and supporters forbade Freedom Day participants from leaving the line to eat, drink, or use the restroom.
At 12:30 pm, a group of 40 state troopers arrived and assisted local law enforcement in intimidating the Freedom Day participants. Because those waiting to register to vote could not leave the line to eat or drink, at one point, a group of organizers attempted to bring food and water to the Black residents waiting in line. These organizers were beaten and shocked with cattle prods by the state and local officials.
At the time, Dallas County was 58% Black, but less than 1% of eligible Black residents were registered to vote. During 1963, Dallas County Sheriff Jim Clark met their voter registration efforts with harassment and violent resistance, joined by other local law enforcement officers and segregationist supporters who participated in violence against Black residents with impunity. Hundreds of Black residents were arrested, beaten, or threatened in Selma during the first half of 1963.
