The House of Bourbon-Penthièvre was an illegitimate branch of the House of Bourbon, thus descending from the Capetian dynasty. It was founded by the duc de Penthièvre (1725–1793), the only child and heir of the comte de Toulouse, the youngest illegitimate son of Louis XIV of France and the marquise de Montespan, and his wife, Marie Victoire de Noailles, the daughter of Anne Jules de Noailles, duc de Noailles.
