Martin Luther King's greatest legacy was his push for the United States to fulfill its promise of equal rights for all people, regardless of the color of their skin. King's "I Have a Dream" speech became one of the most famous speeches of the 20th century.
Martin Luther King's legacy included his dream of a world where children would not be "judged by the color of their skin, but by the content of their character."
As a leader of the NAACP, Martin Luther King, Jr. led African Americans toward racial equality through the power of nonviolence. He did this in many ways through demonstrations, sit-ins, boycotts and the famous March on Washington. In 1964, King was even awarded the Nobel Peace Prize. After his assassination, Congress decided in 1983 to make every third Monday in January Martin Luther King, Jr. Day in honor of his legacy.
