Racial segregation laws in Montgomery, Alabama required Black passengers on public buses to yield their seats to white passengers. On December 1, 1955, Rosa Parks, an African-American woman, was arrested for refusing to comply with this policy, galvanizing the local Black community and civil rights organizations to organize a coordinated protest.
Beginning December 5, 1955, African-American residents of Montgomery boycotted the city's public bus system for over a year. Participants organized carpools, walked, and used other means of transport to avoid riding segregated buses, sustaining economic and social pressure on the transit system throughout the campaign.
On December 20, 1956, the U.S. Supreme Court's ruling in Browder v. Gayle took effect, declaring Alabama and Montgomery bus segregation laws unconstitutional. The boycott became a defining moment in the American civil rights movement and elevated figures such as Martin Luther King Jr. to national prominence as civil rights leaders.
