The Montgomery Bus Boycott was a pivotal 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, as required by segregation laws at the time.

Rosa Parks' act of defiance led to her arrest and galvanized the black community in Montgomery to take a stand against segregation on buses. Civil rights leaders, including Dr. Martin Luther King Jr., organized a boycott of the city's bus system, urging black residents to refuse to ride the buses until they were desegregated.

The boycott lasted for 381 days and was a powerful display of nonviolent resistance and solidarity within the black community. The boycott put financial pressure on the bus company and the city government, ultimately leading to a Supreme Court ruling that declared segregation on public buses unconstitutional.

The Montgomery Bus Boycott is widely regarded as a key turning point in the Civil Rights Movement, highlighting the effectiveness of nonviolent protest in the fight for racial equality. It also brought national attention to the leadership of Dr. King and set the stage for future civil rights victories in the United States.
