Key events include the Montgomery Bus Boycott, the March on Washington, and the Freedom Rides, all of which were pivotal in raising awareness and pushing for legislative changes.

The movement also led to landmark legal victories, such as the Civil Rights Act of 1964 and the Voting Rights Act of 1965, which aimed to abolish segregation and ensure equal rights for African Americans. Activists faced significant opposition and danger, but their efforts were critical in challenging and ultimately changing the legal and social framework of Jim Crow laws, which enforced racial segregation in the South and beyond.
