Martin Luther King, Jr. Day is an American federal holiday marking the birthday of Martin Luther King, Jr. This holiday is observed on the third Monday of January each year, which is around the time of King’s birthday, January 15. This year we celebrate on Monday, January 21st.
Martin Luther King, Jr. was an important figure in American history as a charismatic spokesman for nonviolent activism during the civil rights moment of the 1960s, which successfully protested racial discrimination in federal and state laws.
After King was tragically assassinated in 1968, a campaign began to create a federal holiday in his name. President Ronald Reagan signed the holiday into law in 1983 and it was first observed three years later.
