On January 15, 1929, Martin Luther King, Jr. was born in Atlanta, Georgia, the son of a Baptist minister. King received a doctorate degree in theology and in 1955 helped organize the first major protest of the African American civil rights movement: the successful Montgomery Bus Boycott. He advocated civil disobedience and nonviolent resistance to segregation in the South. The peaceful protests he led throughout the American South were often met with violence, but King and his followers persisted, and the movement gained momentum.

A powerful orator, King won growing support from others who believed in racial justice for all people . In 1963, Bayard Rustin and A. Philip Randolph led the massive March on Washington for Jobs and Freedom; the event’s grand finale was King’s famous “I Have a Dream” speech. Two hundred and fifty thousand people gathered outside the Lincoln Memorial to hear the stirring speech.

In 1964, the civil rights movement achieved two of its greatest successes: the ratification of the 24th Amendment, which abolished the poll tax, and the Civil Rights Act of 1964, which prohibited racial discrimination in employment and education and outlawed racial segregation in public facilities. Later that year, King became the youngest person to win the Nobel Peace Prize. In the late 1960s, King openly criticized U.S. involvement in Vietnam and turned his efforts to winning economic rights for poor Americans. He was assassinated in Memphis, Tennessee, on April 4, 1968.
