The Montgomery Bus Boycott was a pivotal event in the civil rights movement in the United States. It began on December 5, 1955, after Rosa Parks, a Black woman, was arrested for refusing to give up her seat to a white man on a city bus in Montgomery, Alabama. In response to her arrest, the Black community in Montgomery, led by figures such as Dr. Martin Luther King Jr., organized a boycott of the city's segregated bus system.

For 381 days, Black residents of Montgomery refused to ride the buses, choosing instead to walk, carpool, or use other means of transportation. The boycott was a powerful demonstration of nonviolent resistance to segregation and discrimination. It brought national attention to the civil rights movement and helped to galvanize support for desegregation efforts across the country.

In 1956, the U.S. Supreme Court ruled in the case of Browder v. Gayle that segregation on public buses was unconstitutional, effectively ending the boycott. The Montgomery Bus Boycott is remembered as a significant moment in the history of the civil rights movement and a key victory in the struggle for racial equality in the United States.
