Martin Luther King Jr. was a Baptist minister and civil rights activist who played a key role in the American civil rights movement. He grew up in the segregated South and became a pastor in Montgomery, Alabama where he led the Montgomery bus boycott in 1955 to protest racial segregation. In 1963, he delivered his iconic "I Have a Dream" speech during the March on Washington. He continued his advocacy for civil rights and racial equality, organizing additional protests and marches, until he was assassinated in Memphis, Tennessee in 1968.
