Today is Martin Luther King Jr. Day, an American federal holiday celebrating the birthday of American civil rights activist and organizer Martin Luther King, Jr. The campaign for a federal holiday in his honor began soon after his assassination in 1968. President Ronal Reagan signed the holiday into law in 1983, and it was first observed three years later. It was officially observed in all 50 states for the first time in 2000.
