What did Rosa Parks actually do, and why is the usual story incomplete?

On 1 December 1955 in Montgomery, Alabama, Rosa Parks refused to give up her seat on a city bus to a white passenger and was arrested. That much is accurate. The version in which a tired seamstress acted on impulse is not, and Parks spent much of her life correcting it.

She was a long-standing activist. She had been secretary of the Montgomery chapter of the NAACP since 1943, had investigated cases of racial violence and sexual assault against Black women, and only months earlier had attended a training programme on desegregation at the Highlander Folk School in Tennessee. She was politically experienced and knew exactly what refusing would set in motion.

Parks addressed the tiredness explanation directly in her autobiography, writing that she was not physically tired, and that "the only tired I was, was tired of giving in."

The story is also incomplete in another way. Parks was not the first to refuse. In March 1955 a fifteen-year-old, Claudette Colvin, was arrested in Montgomery for the same act, and Mary Louise Smith was arrested in October. Local leaders judged that Parks, an adult with an unimpeachable public record, made a stronger test case.

Her arrest triggered the Montgomery bus boycott, which ran for 381 days and brought Martin Luther King Jr to national prominence. The legal victory, however, came through a different case: Browder v. Gayle, in which Colvin and Smith were among the plaintiffs and Parks was not. The Supreme Court affirmed in 1956 that bus segregation was unconstitutional.

Parks lost her job, faced sustained threats, and eventually moved to Detroit.
