What was Martin Luther King, Jr. primarily known for advocating?

Martin Luther King, Jr. is primarily known for advocating civil rights, particularly in the context of ending racial segregation and discrimination against African Americans in the United States during the 1950s and 1960s. His leadership in the civil rights movement was marked by a commitment to nonviolent protest and the principle of civil disobedience, inspired by Mahatma Gandhi. King’s efforts were crucial in highlighting the injustices faced by African Americans and mobilizing public opinion for legislative changes, including the Civil Rights Act of 1964 and the Voting Rights Act of 1965.

The advocacy for civil rights encompassed various issues, such as voting rights, desegregation, and the elimination of racial discrimination in public accommodations. King's most famous moment was his "I Have a Dream" speech during the March on Washington for Jobs and Freedom in 1963, which articulated his vision of a racially integrated and equitable society. This focus on civil rights significantly advanced the fight for social justice and equality in America, making it a cornerstone of his legacy.
