The Montgomery Bus Boycott was a significant event in the Civil Rights Movement 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 bus.

In response to Parks' arrest, civil rights leaders, including Dr. Martin Luther King Jr., organized a boycott of the city's bus system. African Americans in Montgomery boycotted the buses, walking, carpooling, or cycling instead. The boycott lasted for over a year and put significant economic pressure on the bus company and the city.

The Montgomery Bus Boycott was a pivotal moment in the Civil Rights Movement, demonstrating the power of nonviolent protest and civil disobedience. The boycott ultimately led to a Supreme Court ruling that declared segregation on public buses unconstitutional, marking a major victory for the civil rights movement and inspiring further activism in the fight for racial equality.
