Martin Luther King Jr. was born in 1929 in Atlanta, Georgia. He was a prominent civil rights leader who led the Montgomery Bus Boycott starting in 1955 when Rosa Parks was arrested for refusing to give up her seat to a white passenger. This boycott lasted over a year and ended segregation on Montgomery buses. King's most famous speech was the "I Have a Dream" speech delivered at the 1963 March on Washington where he advocated for racial equality and justice. King was assassinated in 1968 in Memphis, Tennessee.
