David Stewart, Duke of Rothesay

David Stewart (24 October 1378 – 26 March 1402) was heir apparent to the throne of Scotland from 1390 and the first Duke of Rothesay from 1398. He was named after his great-granduncle, David II of Scotland, and also held the titles of Earl of Atholl (1398–1402) and Earl of Carrick (1390–1402). He shares with his uncle and arch-rival, Robert Stewart, first Duke of Albany, the distinction of being first dukes to be created in the Scottish peerage. David never became king. His marriage to Mary Douglas, daughter of Archibald the Grim, the third Earl of Douglas, was without issue.
