As
heir apparent to his father's
dukedom of Sussex,
earldom of Dumbarton, and
barony of Kilkeel, Archie was at birth and by custom entitled to use Prince Harry's senior
subsidiary title, Earl of Dumbarton, as a
courtesy. However, the media reported that the Duke and Duchess decided, instead, that Archie would be styled as
Master Archie Harrison
Mountbatten-Windsor, in accordance with their reported wish that he grow up as a private citizen. Upon the accession of Charles III, Archie became entitled to use the title
prince and
style Royal Highness, as the child of a son of the monarch, pursuant to
letters patent issued by
King George V in 1917. However, sources reported that it was unclear whether he would use that title and style, noting that not all members of the royal family who are eligible for a title choose to use one. In the interview
Oprah with Meghan and Harry, the Duchess of Sussex said that she had been told that changes would be made to remove that entitlement; Charles III's plans for a scaled-down royal family dated back to the 1990s. The official website of the royal family was updated to refer to him as "Prince Archie of Sussex" on 9 March 2023. It was reported that any titles would be used in formal settings, but not in everyday conversational use. ==See also==
