The prominent leader known for his contributions to the civil rights movement in the 1960s is Martin Luther King Jr. He was a key figure advocating for nonviolent resistance in the quest for racial equality in the United States. His leadership during events such as the Montgomery Bus Boycott and the March on Washington exemplified his commitment to justice and civil rights. King’s eloquent speeches, especially his "I Have a Dream" address, inspired millions and galvanized support for legislation aimed at ending segregation and discrimination, including the Civil Rights Act of 1964.
