Yolande of Brittany

Yolande of Brittany (1218–1272), also called Yolande de Dreux, was the only daughter of Alix of Thouars and Peter I of Brittany. As a child she was thrice betrothed, including to Henry III of England, but married none; in 1236 she wed Hugh XI of Lusignan, bringing him the Breton counties of Penthièvre and Porhoët.

When Hugh was killed at Fariskur in 1250, she ruled La Marche and Angoulême as regent for her son Hugh XII until 1256. She died on 10 October 1272.
