The Revolution of the Ganhadores, also known as the 1857 African porters' strike, was a labor strike that involved African porters, known as ganhadores, in the Brazilian city of Salvador, Bahia. The strike began following the passage of a city ordinance that changed the way the ganhadores operated in the city. The strike ended in a partial victory for the strikers, as the city council replaced the ordinance with another one that did away with some of the more unpopular provisions.
