Selma Marches
The Selma Marches were a series of three marches that took place in 1965 between Selma and Montgomery, Alabama. These marches were organized to protest the blocking of Black Americans' right to vote by the systematic racist structure of the Jim Crow South. With the leadership of groups such as the Dallas County Voters League (DCVL), the Student Nonviolent Coordinating Committee (SNCC), and the Southern Christian Leadership Conference (SCLC), the Selma Marches would become a watershed moment that led to the passing of theVoting RightsAct of 1965.
