The American Civil Rights Movement achieved significant victories primarily in the 1960s, with major milestones such as the Civil Rights Act of 1964 and the Voting Rights Act of 1965. These legislative achievements aimed to end racial segregation and discrimination against African Americans, solidifying their legal rights in public spaces and voting processes. The movement included key events such as the March on Washington in 1963, where Dr. Martin Luther King Jr. delivered his famous "I Have a Dream" speech, and grassroots activism that mobilized countless individuals across the nation to demand equality and justice.
