(This particular post has to do with British Royal Protocol.)
Kate’s title is actually Her Royal Highness, Princess William, Duchess of Cambridge, Countess of Strathearn.
And it was never ‘Princess Diana‘
I couldn’t believe it either when I started researching royal titles last week. But it’s very much true. In fact, a princess is only a Princess (insert name) if she was born into the role. Examples include Princesses Beatrice and Eugenie.
Since neither Kate nor Diana were born royals, they were never merely ‘Princess Kate’ or ‘Princess Diana.’
But what about ‘Princess of Wales?’
Well yes, this is true. When Kate and William are passed down the title of Prince and Princess of Wales, they will both be exactly that. However, Kate will carry the title along with her husband’s name, ‘Princess William of Wales.’ Or even, ‘Her Royal Highness Catherine, Princess of Wales.’ Likewise, it was always ‘Her Royal Highness Diana, Princess of Wales.’
Upon her divorce from Prince Charles, by order of the Queen, Diana was stripped of all royal titles.
Queen Consort Catherine
The good news is, I suppose, that when Prince William takes the throne, the Duchess of Cambridge (never Duchess Catherine or Kate) will become Her Majesty Queen Consort Catherine (VI).
And should Prince William and Kate have a baby girl next time around, she’ll be a Princess through and through.
