Counts of Clermont-en-Beauvaisis
The Counts of Clermont-en-Beauvaisis first appear in the early 11th century. Its principal town was Clermont, now in the Oise department but then within the ancient county of Beauvaisis in the province of Île-de-France. Following the death of the childless Theobald VI of Blois, Philip II of France bought the county from his heirs in 1218 and added it to the French crown. It was first granted as an appanage in 1218 to Philip Hurepel; with the extinction of his line, it was granted in 1268 to the House of Bourbon, and was confiscated with the Duchy of Bourbon in 1527.
