The next creation was in 1416 for Charles, youngest son of King Charles VI of France, who succeeded his brother as dauphin in 1417. He succeeded as King Charles VII of France in 1422 when the title merged in the Crown.
The fifth creation was in 1423 for the Scottish nobleman Archibald Douglas, 4th Earl of Douglas, a commander on the French side in the Hundred Years' War. He was killed at the Battle of Verneuil in 1424. His son Lord Wigtown, absent in Scotland, was believed in France to have died without issue, so the title was presumed extinct. When it became apparent that Wigtown had succeeded his father as Earl of Douglas, he was confirmed in the title Duke of Touraine, though not the lands. He died in 1439 and the male line of the fourth Earl of Douglas became extinct on the death of William Douglas, 6th Earl of Douglas, the following year.
Modern courtesy title
The title of "Duke of Touraine" was awarded in 1981 by the legitimist pretender, Alfonso, Duke of Anjou and Cádiz, to his second son, Louis Alphonse. Following his brother's death in 1984 and that of his father in 1989, he respectively became, under the same pretension, "Duke of Bourbon" and "Duke of Anjou". He is the current legitimist pretender to the title of King of France as "Louis XX".
He, in turn, re-created the title for his third son, Henri, born 1 February 2019; having previously conferred on his twin sons, the titles of "Dauphin of France, Duke of Burgundy" and "Duke of Berry" respectively.
