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.
