The Birthday of Martin Luther King, Jr. , often called Martin Luther King Day, is a United States holiday honoring the Reverend Dr. Martin Luther King, Jr., observed on the third Monday of January each year, around the time of King's birthday, January 15. It is the only United States federal holiday commemorating an African-American.
The holiday was the result of a large-scale campaign headed by a number of activists. One of the most notable of these was musician Stevie Wonder, who released the single "Happy Birthday" to popularize the campaign in 1980 and hosted the Rally for Peace Press Conference in 1981.
Opposition to the Bill was led by Sen. Jesse Helms who questioned whether King was important enough to receive such an honor. He was also critical of King's opposition to the Vietnam War and alleged Communist connections.
At the White House Rose Garden on November 2, 1983, U.S. President Ronald Reagan signed a bill creating a federal holiday to honor King. It was observed for the first time on January 20, 1986.
On January 18, 1999, for the first time, Martin Luther King Day was officially observed in all fifty U.S. states. The day is marked by demonstrations for peace, social justice and racial and class equality, as well as a national day of volunteer community service.
On January 16, 2006, Greenville County, South Carolina, was the last county in the U.S. to officially adopt Martin Luther King Day as a paid holiday.
