The movement that critically addressed major social issues in the United States during the 1960s was the Civil Rights Movement. This era was characterized by grassroots activism aimed at ending racial segregation and discrimination against African Americans. Led by figures such as Martin Luther King Jr., Malcolm X, and Rosa Parks, the movement sought to secure equal rights through nonviolent protest, legal challenges, and public awareness campaigns. Significant events, such as the March on Washington and the Selma to Montgomery marches, drew national attention and culminated in landmark legislation like the Civil Rights Act of 1964 and the Voting Rights Act of 1965.
