The Duke of Cambridge is second in line to the throne after his father, Prince Charles , meaning Duchess Kateis set to take on a new title when her husband moves up in the ranks and becomes King William V – but what title will she be granted? Though confusion around this has caused many to report that she’ll be referred to as Queen Catherine VI, HELLO! can report after speaking with royal historian Marlene Koenig, of the Royal Musings blog, that it’s most likely that she’ll simply be called Queen Catherine.
“The wife of the king is by tradition a queen,” Marlene explained, elaborating on why Prince Philip, the Queen’s consort, is known as a prince and not a king. “The husband of a queen, in most monarchies, has to be created a title. A husband does not share a wife’s rank and the same goes for the husbands of princesses.” A perfect example of this is the fact that Jack Brooksbank will not be given a title after saying “I do” to Princess Eugenie .
“Philip was not created a Prince of the UK until 1957. He was given the UK HRH and the titles Duke of Edinburgh, Earl of Merioneth and Baron Greenwich by George VI before the wedding but was not created a British Prince until nearly ten years later,” the historian added.
And although she will be the sixth Catherine to be a consort, the royal will not have a number in her title, as regnal numbers are only given to the sovereign and not a consort. In other words, the Duchess of Cambridge would have had to be born royal in order to receive a numbered title like her husband, who will be styled as the fifth King William.
When Prince Charles ascends the throne, William is set to inherit his father’s titles, according to Marlene, taking on the role of Duke of Cornwall and the Duke of Rothesay. By virtue of their relationship, Kate will take on those same titles as duchess. But that’s not all! The father of three will most likely be given another title by his father, the King: Prince of Wales. Though it is not a title inherited by birth – Charles received it when he turned nine – it’s extremely likely that it will be bestowed upon William, which would open the door for Kate becoming Princess of Wales.
