Constance was Duchess of Brittany between 1186 and 1196. She was the only child of Conan IV, Duke of Brittany and Earl of Richmond, by his wife Margaret of Scotland, countess of Hereford (granddaughter of king David II).
In 1181, Constance married Geoffrey Plantagenet, the fourth son of Henry II of England and Eleanor of Aquitaine, and had two children by him: Eleanor, Fair Maid of Brittany (1184-1241) and Arthur. Geoffrey assumed the title of Duke of Brittany and became the effective ruler of the duchy since the date. However, he died in 1186, stamped by a horse during a tournament. Constance then became ruler of Brittany until 1196, when she abdicated in favour of Arthur.
