The Montgomery Improvement Association (MIA) was formed on December 5, 1955 by black ministers and community leaders in Montgomery, Alabama. Under the leadership of Ralph Abernathy, Martin Luther King, Jr. and Edgar Nixon, the MIA was instrumental in guiding the Montgomery bus boycott, a successful campaign that focused national attention on racial segregation in the South and catapulted King into the national spotlight..
Following Rosa Parks' arrest on 1 December 1955 for failing to vacate her seat for a white passenger on a Montgomery city bus, Jo Ann Robinson of the Women's Political Council and E. D. Nixon of the National Association for the Advancement of Colored People (NAACP) launched plans for a one-day boycott of Montgomery buses on December 5, 1955, the following Monday.
Since no one knew what to expect, the empty buses were a complete surprise. The success of the boycott on December 5, and the excitement on the mass meeting on the evening of that day, removed any doubt about the strong motivation to continue the boycott. As King put it, “[t]he question of calling off the protest was now academic. The enthusiasm of these thousands of people swept everything along like an onrushing tidal wave.” On the afternoon of December 5, the black leadership, consisting of civic and religious leaders of Montgomery, established the Montgomery Improvement Association. Dr. Martin Luther King Jr. was chosen to lead the MIA at the age of 26, with Ralph Abernathy, Jo Ann Robinson, E. D. Nixon, Rufus Lewis and other prominent figures at his side.
At a meeting that evening attended by several thousand community members, the MIA was established to oversee the continuation and maintenance of the boycott, and King, a young minister new to Montgomery, was elected its chairman president. According to Rosa Parks, "Dr. King was chosen in part because he was relatively new to the community and so did not have any enemies." The organization’s overall mission, extended beyond the boycott campaign, as it sought to "improve the general status of Montgomery, to improve race relations, and to uplift the general tenor of the community."
After the MIA’s initial meeting, the executive committee drafted the demands of the boycott and agreed that the campaign would continue until demands were met. Their demands included courteous treatment by bus operators, first-come, first-served seating, and employment of African American bus drivers.
Thus, despite the Supreme Court's decision in Brown v. Board of Education, the MIA was initially willing to accept a compromise that was consistent with separate but equal rather than complete integration. In this respect, it followed the pattern of earlier boycott campaigns in the Deep South during the 1950s. A prime example was the successful boycott of service stations in Mississippi for refusing to provide restrooms for blacks. The organizer of that campaign, T.R.M. Howard of the Regional Council of Negro Leadership, had spoken in Montgomery as King's guest at the Dexter Avenue Baptist Church only days before Parks's arrest.
Over the next year, the MIA organized carpools and held weekly gatherings with sermons and music to keep the black community mobilized. Also during this time period, officers of the organization negotiated with Montgomery city leaders, coordinated legal challenges with the NAACP to the city's bus segregation ordinance, and supported the boycott financially, raising money by passing the plate at meetings and soliciting support from northern and southern civil rights organizations.
Following its success in Montgomery, the MIA became one of the founding organizations of the Southern Christian Leadership Conference (SCLC) in January 1957. The MIA lost some vital momentum after King moved from Montgomery to Atlanta in 1960, but the organization continued campaigns throughout the 1960s, focusing on voter registration, local school integration, and the integration of Montgomery city parks. Although it lost momentum, it did however improve the life of black people living in Montgomery after the boycott.
