Martin Luther King's timeline shows the important events that happened in the life of King. On January 15, 1929, King was born and became the most visible spokesman and leader in the American civil rights movement from 1955 until his assassination in 1968. King advanced civil rights through nonviolence and civil disobedience, inspired by his Christian beliefs and the nonviolent activism of Mahatma Gandhi. As the timeline diagram suggests, King helped organize the 1963 March on Washington, where he delivered his "I Have a Dream" speech on the steps of the Lincoln Memorial. On October 14, 1964, King won the Nobel Peace Prize for combating racial inequality through nonviolent resistance. In 1965, he helped organize two of the three Selma to Montgomery marches. In 1968, King was planning a national occupation of Washington, D.C., to be called the Poor People's Campaign, when he was assassinated on April 4 in Memphis, Tennessee.
