The movement that sought to end racial segregation in the United States is known as the Civil Rights Movement. Emerging primarily in the 1950s and 1960s, it involved grassroots activism, legal challenges, and significant public demonstrations led by figures like Martin Luther King Jr. and organizations such as the NAACP. The movement aimed to achieve equality for African Americans and dismantle systematic injustices rooted in Jim Crow laws. Key milestones included the Brown v. Board of Education decision, the March on Washington, and the passage of landmark legislation like the Civil Rights Act of 1964.
