37. Martin Luther King Jr. Day falls on the third Monday in
January, close to the civil rights activist’s birthday on Jan. 15.
King was the leading spokesman for nonviolent activism in the
civil rights movement, advocating for the victims of injustice and
economic disadvantage and protesting racial discrimination. He
won the Nobel Peace Prize in 1964. The campaign for a federal
holiday in King’s honor began soon after his assassination in
1968. Congress passed the legislation, President Ronald Reagan
signed it into law in 1983, and it was first recognized three
years later. Some states resisted the holiday, giving it
alternative names, combining it with other holidays or not
observing it, and it was officially observed in all 50 states for
the first time in 2000. (AP/Yahoo News)
