Why was Diana a princess, but Kate is only a Duchess?

To be a Duchess, they must first prove their family married into a Dutch family. She was unable to prove that. Her loss.

Prince Charles is the Prince of Wales, therefore Diana was the Princess of Wa;les. William is a hereditary prince, when his father becomes King he will become the prince of Wales and Catherine will become Princess of Wales. The title Duchess of Cambridge gives her a title and prestige that simply a princess title would not give her.

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.
