context_page_description: Aquitaine, archaic Guyenne/Guienne, is a historical region of southwestern France and a former administrative region of the country. Since 1 January 2016 it has been part of the region of Nouvelle-Aquitaine. It is situated in the far southwest corner of Metropolitan France, along the Atlantic Ocean and the Pyrenees mountain range on the border with Spain. It is composed of the five departments of Dordogne, Lot-et-Garonne, Pyrénées-Atlantiques, Landes and Gironde. In the Middle Ages, Aquitaine was a kingdom and a duchy, whose boundaries fluctuated considerably.
context_section_description: After the 843 Treaty of Verdun, the defeat of Pepin II and the death of Charles the Bald, the Kingdom of Aquitaine (subsumed in West Francia) ceased to have any relevance and the title of King of Aquitaine took on a nominal value. In 1058, the Duchy of Vasconia (Gascony) and Aquitaine merged under the rule of William VIII, Duke of Aquitaine.    
  The title "Duke of Aquitaine" was held by the counts of Poitiers from the 10th to the 12th century.
