The Montgomery Bus Boycott was a significant event in the Civil Rights Movement that took place in Montgomery, Alabama in 1955-1956. The boycott was organized in response to the arrest of Rosa Parks, a Black woman who refused to give up her seat on a segregated bus to a white passenger. Parks' act of resistance sparked a wave of protest and activism led by civil rights leaders such as Martin Luther King Jr.

The boycott lasted for 381 days and involved the African American community in Montgomery refusing to use the city's public buses in protest of racial segregation on the buses. This nonviolent protest was a pivotal moment in the Civil Rights Movement, demonstrating the power of collective action and civil disobedience in the fight against segregation and racial injustice.

The Montgomery Bus Boycott ultimately led to the Supreme Court ruling in Browder v. Gayle that declared segregation on public buses unconstitutional, marking a significant victory for the Civil Rights Movement and inspiring further efforts to end racial discrimination and segregation across the United States.
