Martin Luther King Jr. (January 15, 1929 – April 4, 1968) was an American Christian minister and activist who became the most visible spokesperson and leader in the Civil Rights Movement from 1955 until his assassination in 1968. Born in Atlanta, Georgia, King is best known for advancing civil rights through nonviolence and civil disobedience, inspired by his Christian beliefs and the nonviolent activism of Mahatma Gandhi.

King led the 1955 Montgomery bus boycott and in 1957 became the first president of the Southern Christian Leadership Conference (SCLC). With the SCLC, he led an unsuccessful 1962 struggle against segregation in Albany, Georgia, and helped organize the nonviolent 1963 protests in Birmingham, Alabama. He helped organize the 1963 March on Washington, where he delivered his famous "I Have a Dream" speech.

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. His death was followed by riots in many U.S. cities. Allegations that James Earl Ray, the man convicted of killing King, had been framed or acted in concert with government agents persisted for decades after the shooting.

Sentenced to 99 years in prison for King's murder, effectively a life sentence as Ray was 41 at the time of conviction, Ray served 29 years of his sentence and died from hepatitis in 1998 while in prison.
