2021 Martin Luther King Jr. Day

Martin Luther King Jr. Day (officially Birthday of Martin Luther King, Jr. and sometimes referred to as MLK Day) is an American federal holiday marking the birthday of Martin Luther King Jr. It is observed on the third Monday of January each year, which is around King's birthday, January 15. The holiday is similar to holidays set under the Uniform Monday Holiday Act. The earliest Monday for this holiday is January 15 and the latest is January 21.

King was the chief spokesperson for nonviolent activism in the Civil Rights Movement, which successfully protested racial discrimination in federal and state law. The campaign for a federal holiday in King's honor began soon after his assassination in 1968. President Ronald Reagan signed the holiday into law in 1983, and it was first observed three years later. At first, some states resisted observing the holiday as such, giving it alternative names or combining it with other holidays. It was officially observed in all 50 states for the first time in 2000.

Martin Luther King, Jr. was a social activist and Baptist minister who played a key role in the American civil rights movement from the mid-1950s until his assassination in 1968. King sought equality and human rights for African Americans, the economically disadvantaged and all victims of injustice through peaceful protest. He was the driving force behind watershed events such as the Montgomery Bus Boycott and the 1963 March on Washington, which helped bring about such landmark legislation as the Civil Rights Act and the Voting Rights Act. King was awarded the Nobel Peace Prize in 1964 and is remembered each year on Martin Luther King, Jr. Day, a U.S. federal holiday since 1986.
