Martin Luther King was an American civil rights leader who worked to bring about social, political, and economic equality for African-Americans by peaceful means. During the 1950s and 1960s, his struggle for racial justice won the support of millions of persons, both black and white. He preached "nonviolent resistance," and it reached a high point in Washington, DC on August 28, 1963, where more than 200, 000 persons marched from the Washington Monument to the Lincoln Memorial in order to express concern over civil rights. Millions also watched on television when King told the crowd, "I have a dream that one day this nation will rise up and live out the true meaning of its creed: 'We hold these truths to be self-evident: that all men are created equal.'" In spite of his great emphasis on nonviolence, King often became the target of violence. He was stabbed in New York City and stoned in Chicago. His home in Montgomery, Alabama, was bombed. Finally, violence took away his life at the age of thirty-nine. A hidden rifleman shot and killed him on April 4, 1968, in Memphis, Tennessee. Martin Luther King has left us a legacy of courage and social commitment. According to him, "The function of education...is to teach one to think intensively and to think critically. But education which stops with efficiency may prove the greatest menace to society. The most dangerous criminal may be the man gifted with reason, but with no morals."
