The Montgomery Bus Boycott was a significant event in American civil rights history that took place in Montgomery, Alabama, from December 1955 to December 1956. The boycott was sparked by the arrest of Rosa Parks, a Black woman, who refused to give up her seat to a white passenger on a segregated city bus. Her arrest led to a coordinated effort by Black community leaders, including Dr. Martin Luther King Jr., to organize a boycott of the city's bus system in protest of racial segregation and mistreatment on public transportation.

The boycott was a key moment in the civil rights movement, as it demonstrated the power of nonviolent protest and collective action to bring about change. The Black community in Montgomery showed remarkable unity and resilience, organizing carpools and walking long distances to work in order to economically pressure the bus company and local government to end segregation on buses.

After 381 days of protest, the U.S. Supreme Court ruled in the case of Browder v. Gayle that segregation on public buses was unconstitutional, leading to the desegregation of Montgomery's bus system. The Montgomery Bus Boycott not only brought about a significant victory in the fight against segregation but also galvanized the civil rights movement and marked a turning point in the struggle for racial equality in America.
