The Bristol Bus Boycott, announced on this day in 1963, arose from the refusal of the Bristol Omnibus Company to employ black or Asian bus crews in the city of Bristol, England. It succeeded in ending the "colour bar" after four months.

The action was led by four young West Indian men, Roy Hackett, Owen Henry, Audley Evans and Prince Brown, who formed an action group later known as the "West Indian Development Council". Unhappy with the lack of progress in fighting discrimination by the West Indian Association and inspired by Montgomery Bus Boycott in the United States, the activists decided on a bus boycott in Bristol to win their rights.

The boycott drew national attention to racial discrimination in Britain and continued for several months. The boycott was finally resolved on August 27th, 1963, when a mass meeting of 500 bus workers agreed to officially put an end to the "colour bar". On September 17th, Raghbir Singh, a Sikh, became Bristol's first non-white bus conductor.

The Bristol Bus Boycott was influential in the passing of the Race Relations Act of 1965 which banned "racial discrimination in public places" and the Race Relations Act 1968, which extended those provisions to employment and housing.
