Montgomery Bus Boycott
From Tardis Wiki, the free Doctor Who reference
The Montgomery Bus Boycott was an historical event in civil rights history. Started by Rosa Parks in the American state Alabama on first of December, 1955, the boycott was enacted by black bus passengers throughout Montgomery, who refused to use the segregated bus services for over a year in the state. As such, law relented and the segregated bus services were ended by law in 1956. (TV: Rosa)
