First of all she isn't called Princess Kate. Her full title is: -Her Royal Highness Princess William, Duchess of Cambridge, Countess of Strathearn and Baroness Carrickfergus. Or for short: -Her Royal Highness The Duchess of Cambridge.
If she divorced then the precedent would be that she would loose her titles but would be able to use a courtesy title until she married again which would be: -Catherine, Duchess of Cambridge There has never been a British Queen who has been divorce before so there is no precedent. However if I was to guess her title would change from: -Her Majesty The Queen There are several potential possibilities: Follow the precedent of divorce peers: -Catherine, Queen (of the UK) or something similar to a dowager or ex-monarch -Queen Catherine.
She would no longer be Her Royal Highness The Princess William, Duchess of Cambridge. She'd be Catherine, Duchess of Cambridge. Divorced royal women lose the HRH and their title of Princess.
The use their first names followed by their former title. HRH The Princess of Wales became Diana, Princess of Wales. HRH The Duchess of York became Sarah, Duchess of York.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
