In 1351, during the Breton War of Succession (part of the Hundred Years' War), the town was occupied by the Montfortist faction, supported by the English. The rival French-supported Blois faction controlled nearby Josselin. Two groups of approximately 30 English and French knights staged a tournament at a spot between the two towns, to show their prowess and make money by capturing opponents. The Franco-Breton team eventually won after killing or capturing the Anglo-Breton force. This was later known as the Combat of the Thirty.
