The Montgomery Bus Boycott was a key event in the Civil Rights Movement that took place in Montgomery, Alabama, in 1955-1956. 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 city bus. Her act of defiance led to her arrest and galvanized the African American community in Montgomery to take action against segregated seating on city buses.

Led by civil rights leaders such as Dr. Martin Luther King Jr., the Black community in Montgomery organized a boycott of the city's bus system, choosing to walk, carpool, or use other modes of transportation instead of riding the buses. The boycott lasted for over a year, during which time Black residents faced harassment, violence, and arrests for their participation.

The Montgomery Bus Boycott was a significant turning point in the Civil Rights Movement, demonstrating the power of nonviolent protest and collective action. The Supreme Court eventually ruled that segregated seating on buses was unconstitutional, leading to the desegregation of public transportation in Montgomery and inspiring similar boycotts and protests across the South. The success of the boycott elevated Dr. Martin Luther King Jr. to national prominence as a civil rights leader and set the stage for further activism and change in the fight for racial equality.
