Originally, the Duchy of Chartres (duché de Chartres) was the comté de Chartres, a County. The title of comte de Chartres thus became duc de Chartres. This duchy–peerage was given by Louis XIV of France to his nephew, Philippe II d'Orléans, at his birth in 1674. Philippe II was the younger son and heir of the king's brother, Philippe de France, Duke of Orléans.

Theobold I was also known as Theobald the Cheat, or Theobald the Old. He was given the nickname “the Cheat” fighting with his neighbours, among them the kings of France, the dukes of Normandy, and the church of Reims.[2]
