Different campaigns targeted different mechanisms of exclusion. The Montgomery bus boycott used sustained local economic pressure against segregated transit. Sit-ins challenged segregated service directly and helped create a new student movement. Freedom Rides tested whether federal rules governing interstate travel would be enforced against violent resistance. Freedom Summer built voter-registration and political-education efforts in Mississippi, while the Selma campaign exposed the violence and administrative barriers surrounding Black voting. Marches brought visibility, but less visible work-canvassing, teaching, collecting affidavits, raising bail, and maintaining local organizations-made the public events possible.

Movement pressure changed institutions without acquiring their formal powers. Lawyers could ask courts for injunctions; organizers could reveal facts and increase participation; boycotts could impose economic costs; journalists could widen the audience; voters could alter electoral incentives. Courts could invalidate unconstitutional government action, Congress could enact national rules, and executive officials could investigate, sue, administer funds, and enforce orders. The Civil Rights Act of 1964 addressed segregation in public accommodations, discrimination in covered employment, and discrimination in federally supported programs through different titles. The Voting Rights Act of 1965 supplied federal tools against racial exclusion from voting. Those statutes were political achievements of organized pressure as well as exercises of congressional power.

No single tactic, leader, branch, or law explains the movement's results. Strategic disagreements concerned nonviolence, self-defense, litigation, electoral work, federal alliances, economic justice, leadership, and the pace of change. Victories also required administration and could produce new conflicts over proof, coverage, remedies, and compliance. The next lesson isolates civil disobedience because it is one tactic within this larger ecosystem, not a synonym for the movement as a whole. For CLEP purposes, connect each actor to its actual capacity: movements mobilize people and change political costs; courts announce and enforce judgments; Congress legislates; presidents and agencies execute federal law; state and local institutions implement or resist it.
