Duke of Aquitaine
The duke of Aquitaine (Occitan: Duc d'Aquitània, French: Duc d'Aquitaine, IPA: [dyk dakitɛn]) was the ruler of the medieval region of Aquitaine (not to be confused with modern-day Aquitaine) under the supremacy of Frankish, English, and later French kings. As successor states of the Visigothic Kingdom (418–721), Aquitania (Aquitaine) and Languedoc (Toulouse) inherited both Visigothic law and Roman Law, which together allowed women more rights than their contemporaries would enjoy until the 20th century.
