Henrietta of England (16 June 1644 (26 June n.s.) – 30 June 1670) was the youngest daughter of King Charles I and his wife, Henrietta Maria of France. Fleeing England with her governess at the age of three, she moved to the court of her first cousin Louis XIV of France, where she was known as Minette. After she married Philippe of France, brother of King Louis XIV, known as Monsieur at court, she became known as Madame. Very popular with the court, her marriage was marked by frequent tensions. Henrietta was instrumental in negotiating the Secret Treaty of Dover prior to her unexpected death in June 1670. Jacobite claims to the throne of Great Britain following the death of Henry Benedict Stuart descend from her through her daughter Anne Marie, Queen of Sardinia.
