Duke of Gascony

House of Plantagenet

After 1204, the title of Duke of Gascony was held by the kings of England. Lord Edward, son of Henry III and later King Edward I, was named Duke of Gascony in 1249. On his accession to the throne in 1272, the title was reunited with the kingdom of England and treated as another name for the Duchy of Aquitaine, generally inclusive of Guyenne.
