King organized the Montgomery Bus Boycott after Parks was arrested and jailed for refusing to give up her seat to a White man on a city bus.

The boycott was a civil rights protest in which African Americans refused to ride city buses in Montgomery due to segregated seating. It lasted over a year, beginning on December 5, 1955 and ending on December 20, 1956.

It led to a Supreme Court ruling in 1956 which desegregated public transportation in Montgomery.

Parks was honored with a statue in downtown Montgomery in December 2019. She passed away in October 2005 at the age of 92.
