Martin Luther King Jr. Day celebrates Martin Luther King as an important civil rights activist. Martin Luther King Day is a federal holiday held on the third Monday of January.
He was a leader in the movement to end racial segregation in the United States. His most famous address was the "I Have A Dream" speech. He was an advocate of non-violent protest and became the youngest man to be awarded the Nobel Peace Prize. He was assassinated in 1968.
In 1968, shortly after Martin Luther King died, a campaign was started for his birthday to become a holiday to honor him. After the first bill was introduced, trade unions lead the campaign for the federal holiday. It was endorsed in 1976. Following support from the musician Stevie Wonder with his single "Happy Birthday" and a petition with six million signatures, the bill became law in 1983.
