Ever wondered where did Royal surname "Mountbatten-Windsor" come from? Did you know that at one point British Royals had no surname?

Well, British Royal Family name has long history... Prior to 1917, members of the British Royal Family had no surname, but only the name of the house or dynasty to which they belonged. However, in 1917 King George V changed the Royal Family name from German-sounded (and German by origin) Saxe-Coburg-Gotha to Windsor and abolished all German titles held by his family. Remember, it was during First World War and in Britain there were strong anti-German feelings among British citizens.

In 1960 The Queen of England and the Duke of Edinburgh decided to have their own direct descendants be named differently, thus distinguishing them among other Royal Family members (yeah, too many Royals in the word :)

So, what they did - they included Duke's surname to create new Mountbatten-Windsor dynasty. Now, all of the Queen's direct descendents will carry this surname (unless they are His or Her Royal Highness or Prince/Princess).
