The Montgomery bus boycott was a political and social protest campaign against the policy of racial segregation on the public transit system of Montgomery, Alabama. It was a foundational event in the civil rights movement in the United States. The campaign lasted from December 5, 1955 – the Monday after Rosa Parks, an African-American woman, was arrested for her refusal to surrender her seat to a white person – to December 20, 1956, when the federal ruling Browder v. Gayle, a United States Supreme Court decision that declared the Alabama and Montgomery laws that segregated buses were unconstitutional, took effect.
Background
Before the bus boycott, Jim Crow laws mandated the racial segregation of the Montgomery Bus Line. As a result of this segregation, African Americans were not hired as drivers, were forced to ride in the back of the bus, and were frequently ordered to surrender their seats to white people even though black passengers made up 75% of the bus system's riders. Many bus drivers treated their black passengers poorly beyond the law: African-Americans were assaulted, shortchanged, and left stranded after paying their fares.
The year before the bus boycott began, the Supreme Court and Warren Court decided unanimously, in the case of Brown v. Board of Education, that racial segregation in schools was unconstitutional. The reaction by the white population of the Deep South was "noisy and stubborn". Discontented white southerners joined the White Citizens' Council as a result of the decision.
Although it is often framed as the start of the civil rights movement, the boycott occurred at the end of many black communities' struggles in the South to protect black women, such as Recy Taylor, from racial violence. The boycott also took place within a larger statewide and national movement for civil rights, including court cases such as Morgan v. Virginia, the earlier Baton Rouge bus boycott, the arrests of 15-year-old Claudette Colvin and 18-year-old Mary Louise Smith, among others, for refusing to give up their seat on a Montgomery bus.
History
Under the system of segregation on Montgomery buses, the 10 front seats were reserved for white people at all times. The 10 back seats were supposed to be reserved for black people at all times. The middle section consisted of 16 unreserved seats for white and black people on a segregated basis. White people filled the middle seats from the front to back, and black people filled seats from the back to front until the bus was full. If other black people boarded the bus, they were required to stand. If another white person boarded the bus, then everyone in the black row nearest the front had to get up and stand so that a new row for white people could be created; it was illegal for white and black people to sit next to each other. When Rosa Parks refused to give up her seat for a white person, she was sitting in the first row of the middle section.
Often when boarding the buses, black people were required to pay at the front, get off, and reenter the bus through a separate door at the back. Where white people paid at the front, sat in the front, and exited in the front. Occasionally, bus drivers would drive away before black passengers were able to reboard. National City Lines owned the Montgomery Bus Line at the time of the Montgomery bus boycott. Under the leadership of Walter Reuther, the United Auto Workers donated almost $5,000 (equivalent to $60,093 in 2025) to the boycott's organizing committee.
Rosa Parks
Rosa Parks (February 4, 1913 – October 24, 2005) was a seamstress by profession; she was also the secretary for the Montgomery chapter of the National Association for the Advancement of Colored People (NAACP). Twelve years before her history-making arrest, Parks was stopped from boarding a city bus by driver James F. Blake, who ordered her to board at the rear door and then drove off without her. Parks vowed never again to ride a bus driven by Blake. As a member of the NAACP, Parks was an investigator assigned to cases of sexual assault. In 1945, she was sent to Abbeville, Alabama, to investigate the gang rape of Recy Taylor. The protest that arose around the Taylor case was the first instance of a nationwide civil rights protest, and it laid the groundwork for the Montgomery bus boycott.
In 1955, Parks completed a course in "Race Relations" at the Highlander Folk School in Tennessee, where nonviolent civil disobedience had been discussed as a tactic. On December 1, 1955, Parks was sitting in the foremost row in which black people could sit (in the middle section). When a white man boarded the bus, the bus driver told everyone in her row to move back. At that moment, Parks realized that she was again on a bus driven by Blake. While all of the other black people in her row complied, Parks refused, and she was arrested for failing to obey the driver's seat assignments, as city ordinances did not explicitly mandate segregation but did give the bus driver authority to assign seats. Found guilty on December 5, Parks was fined $10 plus a court cost of $4 (combined total equivalent to $168 in 2025), and she appealed. This movement also sparked riots leading up to the 1956 Sugar Bowl.
E. D. Nixon
Some action against segregation had been in the works for some time before Parks' arrest, under the leadership of E. D. Nixon, president of the local NAACP chapter and active member of the Brotherhood of Sleeping Car Porters. Nixon intended that her arrest be a test case to allow Montgomery's black citizens to challenge segregation on the city's public buses. With this goal, community leaders had been waiting for the right person to be arrested, a person who would anger the black community into action, who would agree to test the segregation laws in court, and who, most importantly, was "above reproach". When Colvin was arrested in March 1955, Nixon thought he had found the perfect person, but the teenager turned out to be pregnant. Nixon later explained, "I had to be sure that I had somebody I could win with." Parks was a good candidate because of her employment and marital status, along with her good standing in the community.
Between Parks' arrest and trial, Nixon organized a meeting of local ministers at Martin Luther King Jr.'s church. Though Nixon could not attend the meeting because of his work schedule, he arranged that no election of a leader for the proposed boycott would take place until his return. When he returned, he caucused with Ralph Abernathy and Rev. E.N. French to name the association to lead the boycott to the city (they selected the "Montgomery Improvement Association", "MIA"), and they selected King (Nixon's choice) to lead the boycott. Nixon wanted King to lead the boycott because the young minister was new to Montgomery and the city fathers had not had time to intimidate him. At a subsequent, larger meeting of ministers, Nixon's agenda was threatened by the clergymen's reluctance to support the campaign. Nixon was indignant, pointing out that their poor congregations worked to put money into the collection plates so these ministers could live well, and when those congregations needed the clergy to stand up for them, those comfortable ministers refused to do so. Nixon threatened to reveal the ministers' cowardice to the black community, and King spoke up, denying he was afraid to support the boycott. King agreed to lead the MIA, and Nixon was elected its treasurer.
Boycott
On the night of Parks' arrest, the Women's Political Council, led by Jo Ann Robinson, printed and circulated a flyer throughout Montgomery's black community that read as follows:
Another Negro woman has been arrested and thrown in jail because she refused to get up out of her seat on the bus for a white person to sit down.
It is the second time since the Claudette [Colvin] case that a Negro woman has been arrested for the same thing[.] This has to be stopped.
Negroes have rights too, for if Negroes did not ride the buses, they could not operate. Three-fourths of the riders are Negro, yet we are arrested, or have to stand over empty seats. If we do not do something to stop these arrests, they will continue. The next time it may be you, or your daughter, or mother.
This woman's case will come up on Monday. We are, therefore, asking every Negro to stay off the buses Monday in protest of the arrest and trial. Don't ride the buses to work, to town, to school, or anywhere on Monday.
You can afford to stay out of school for one day if you have no other way to go except by bus. You can also afford to stay out of town for one day. If you work, take a cab, or walk. But please, children and grown-ups, don't ride the bus at all on Monday. Please stay off of all buses Monday.
The next morning there was a meeting led by the new Montgomery Improvement Association (MIA) head, King, where a group of 16 to 18 people gathered at the Mt. Zion Church to discuss boycott strategies. At that time Rosa Parks was introduced but not asked to speak, despite a standing ovation and calls from the crowd for her to speak; she asked someone if she should say something, but they replied, "Why, you've said enough." A citywide boycott of public transit was proposed, with three demands: 1) courteous treatment by bus operators, 2) passengers seated on a first-come, first-served basis, with black people seated in the back half and white people seated in the front half, and 3) black people would be employed as bus operators on routes predominately taken by black people.
This demand was a compromise for the leaders of the boycott, who believed that the city of Montgomery would be more likely to accept it rather than a demand for full integration of the buses. In this respect, the MIA leaders followed the pattern of 1950s boycott campaigns in the Deep South, including the successful boycott a few years earlier of service stations in Mississippi for refusing to provide restrooms for Black people. The organizer of that campaign, T. R. M. Howard of the Regional Council of Negro Leadership, had spoken on the lynching of Emmett Till as King's guest at the Dexter Avenue Baptist Church only four days before Parks's arrest. Parks was in the audience and later said that Emmett Till was on her mind when she refused to give up her seat.
The MIA's demand for a fixed dividing line was to be supplemented by a requirement that all bus passengers receive courteous treatment by bus operators, be seated on a first-come, first-served basis, and that Black people be employed as bus drivers. The proposal was passed, and the boycott was to commence the following Monday. To publicize the impending boycott it was advertised at black churches throughout Montgomery the following Sunday.
On Saturday, December 3, it was evident that the black community would support the boycott, and very few black people rode the buses that day. On December 5, a mass meeting was held at the Holt Street Baptist Church to determine if the protest would continue. Given twenty minutes' notice, King gave a speech asking for a bus boycott and attendees enthusiastically agreed. Starting December 7, J Edgar Hoover's FBI noted the "agitation among negroes" and tried to find "derogatory information" about King.
The boycott proved extremely effective, with enough riders lost to the city transit system to cause serious economic distress. Martin Luther King later wrote, "[a] miracle had taken place." Instead of riding buses, boycotters organized a system of carpools, with car owners volunteering their vehicles or themselves driving people to various destinations. Some white housewives also drove their black domestic servants to work. When the city pressured local insurance companies to stop insuring cars used in the carpools, the boycott leaders arranged policies at Lloyd's of London.
