Summary

From December 1955 to December 1956, African American residents of Montgomery, Alabama, boycotted city buses to end segregated seating. The campaign, led by the Montgomery Improvement Association and Dr. Martin Luther King Jr., succeeded when the U.S. Supreme Court declared bus segregation unconstitutional. The boycott inspired the broader civil rights movement and led to the formation of the Southern Christian Leadership Conference.

Background

In Montgomery, Alabama, and across the southern United States, laws required African Americans to sit at the back of buses and yield seats to white passengers. The Women’s Political Council had been working to end bus segregation since 1946, and there was talk of a citywide boycott as early as 1954. The arrest of Rosa Parks on December 1, 1955, for refusing to give up her seat sparked the boycott.

What happened

On December 5, 1955, 90 percent of Montgomery’s African American community stayed off public buses in a one-day boycott called by the Women’s Political Council. [source: nv-database] That afternoon, leaders founded the Montgomery Improvement Association (MIA) with Rev. [source: nv-database] Martin Luther King Jr. [source: nv-database] as president, and a mass meeting voted to continue the boycott. [source: nv-database] The MIA organized an intricate carpool system after city officials threatened taxi drivers who offered reduced fares. [source: nv-database] On January 30, 1956, King’s home was bombed, but he calmed the crowd and urged nonviolence. [source: nv-database] In February 1956, city officials obtained injunctions and indicted leaders under an anti-conspiracy law; King was convicted and ordered to pay $500 or serve 386 days, gaining national support. [source: nv-database] Bayard Rustin and later Glenn Smiley advised King on nonviolent strategy. [source: nv-database] In June 1956, a federal district court ruled bus segregation unconstitutional, and the city appealed. [source: nv-database] On November 13, 1956, the U.S. [source: nv-database] Supreme Court affirmed the ruling. [source: nv-database] The boycott officially ended on December 20, 1956, when the Court order reached Montgomery, and the first integrated bus rode the next day. [source: nv-database] Violence escalated in January 1957, including bombings of churches and homes, but bus service returned to normal after arrests [source: nv-database].
