The civil rights movement achieved significant victories through major advocacy and grassroots organizing. Key milestones included the Civil Rights Act of 1964, which outlawed discrimination in employment and public accommodations, and the Voting Rights Act of 1965, aimed at eliminating barriers to voting for African Americans. Grassroots efforts, like local organizing and protests, mobilized community support and highlighted systemic inequality. Leaders such as Martin Luther King Jr. used nonviolent resistance to confront segregation and discrimination, fostering a broader societal awareness that ultimately shifted public opinion and transformed U.S. laws and policies.
