The Revolt of the papier timbré was an anti-fiscal revolt in the west of Ancien Régime France, during the reign of Louis XIV from April to September 1675. It was fiercest in Lower Brittany, where it took on an anti-lordly tone and became known as the revolt of the Bonnets rouges or revolt of the Torrebens. It was unleashed by an increase in taxes, including the papier timbré, needed to authenticate official documents.
