Martin Luther King Jr. Day is Monday, honoring one of the greatest civil rights leaders of all time.
Celebrated this year on January 17, 2011, the holiday falls on the third Monday of January every year, right around King's birthday, which is January 15. King would have been 82 this year.
His "I Have A Dream" speech was recited on August 28, 1963 during the March on Washington. King spoke in front of the Lincoln Memorial.
Perhaps the most famous of King's speeches, the repetition "I have a dream" resonated with marches and became a symbol of civil rights. The speech was initially titles "Normalcy, Never Again," but as King became more and more impassioned, he began to "preach" continuously repeating the phrase.
