Happy Birthday, single written, produced, and performed by Stevie Wonder in 1981 to popularize the campaign, and continued his fight for the holiday, holding the Rally for Peace Press Conference in 1981.
United States President Ronald Reagan approved the creation of the holiday, signing it into existence on November 2, 1983. The first official Martin Luther King, Jr. Day, held the third Monday in January of each year, was held on January 20, 1986, and was commemorated with a large-scale concert, where Stevie Wonder was the headlining performer. It wasn’t until 2000 (seventeen years after the first observance) that the holiday was officially observed in all 50 states for the first time.
