King and the Rev. Ralph Abernathy are taken by a police officer after they led a line of demonstrators into the business section of Birmingham, Alabama, in April 1963. While in solitary confinement, King wrote his “Letter from Birmingham Jail,” which said people have a moral responsibility to disobey unjust laws. AP

King addresses a crowd during the March on Washington on August 28, 1963. It was here, on the steps of the Lincoln Memorial, that he delivered his iconic “I Have a Dream” speech. “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.’ ” CNP/Getty Images

A bomb blast at the Sixteenth Street Baptist Church killed four African-American girls. “These children — unoffending, innocent and beautiful — were the victims of one of the most vicious and tragic crimes ever perpetrated against humanity,” King said in his eulogy. “And yet they died nobly. They are the martyred heroines of a holy crusade for freedom and human dignity.” Burton Mcneely/The LIFE Images Collection/Getty Images

King and his wife lead the final stretch of a march from Selma, Alabama, to the state capital of Montgomery on March 25, 1965. About 25,000 people had marched to protest discriminatory practices, such as poll taxes and literacy tests, that prevented many black people from voting in the South. It was the last of three marches that month. The first ended in clashes with police and is now known as “Bloody Sunday.” AP

King speaks to protesters at the conclusion of the Selma to Montgomery march. It was here that he famously said “the arc of the moral universe is long, but it bends toward justice.” A few months later, President Johnson signed the Voting Rights Act, which ensured that everyone’s right to vote would be protected and enforced.

This photo, taken during a rally in Memphis on April 3, 1968, is one of the last pictures ever taken of King. Here, he delivered his final speech, which is now known as the “I’ve Been to the Mountaintop” speech. “We’ve got some difficult days ahead,” he said. “But it doesn’t matter with me now. Because I’ve been to the mountaintop. And I don’t mind. Like anybody, I would like to live a long life. Longevity has its place. But I’m not concerned about that now. I just want to do God’s will. And He’s allowed me to go up to the mountain. And I’ve looked over. And I’ve seen the promised land. I may not get there with you. But I want you to know tonight, that we, as a people, will get to the promised land.” Bettmann Archive/Getty Images

On April 4, 1968, King was fatally shot on the balcony of the Lorraine Motel in Memphis. Here, people stand over King’s fallen body as they point in the direction that the gunshots came from.
