Rosa Parks Day is a holiday in honor of the civil rights leader Rosa Parks, celebrated in the U.S. states of Missouri and Massachusetts on her birthday, February 4, in Michigan and California on the first Monday after her birthday, and in Ohio, Texas, Alabama, Tennessee, Oregon and several cities and counties on the day she was arrested, December 1.

[3] It is also celebrated by the Columbus Ohio bus system (COTA) with a special tribute to the late civil rights leader.

[19] In 1955, Parks completed a course in "Race Relations" at the Highlander Folk School in Tennessee where nonviolent civil disobedience had been discussed as a tactic.

Parks' action gained notoriety leading to the Montgomery bus boycott, which was a seminal event in the civil rights movement, and was a political and social protest campaign against the policy of racial segregation on the public transit system of Montgomery, Alabama.

[23] Many important figures in the civil rights movement took part in the boycott, including Reverend Martin Luther King Jr. and Ralph Abernathy.
