When a woman marries in UK she takes the surname of her husband. The Queen is no exception, unless Letters Patent are issued stating otherwise, as George VI did when Elizabeth married Prince Philip. (a) So, the House of Stuart changed to Hanover, when George of Hanover inherited the crown from his distant cousin Anne Stuart, Queen of UK.
(b) When Victoria of Hanover, Queen of UK married Albert Saxe-Coburg and Gotha, then the House of Hanover was succeeded by the House of Saxe-Coburg and Gotha. (c) Then George V, son of Edward VII Saxe-Coburg and Gotha, decided to change his "surname", so the House was renamed to Wettin. (d) Then George V Wettin decided to change it *(again) to Windsor.
(e) When Elizabeth II Windsor married Philip Mountbatten (actually he was Philip Schleswig-Holstein-Sonderburg-Glücksburg... but that's another story), the royal house REMAINED Windsor, because George VI chose so... Yes, I know its a lot of fuzz about nothing, but they are royals, what do you expect?
They are royal House Names, sort of like surnames. Stuart was the royal House Name of Scotland, which became the royal House Name of England, too, when James VI Stuart of Scotland succeeded his cousin, Elizabeth I Tudor, on the throne of England. The House Name in the UK has changed several times, though the incumbents of the throne have all been related.
Windsor was adopted during World War I when the previous House Name under Queen Victoria and her son Edward VII -- Saxe-Coburg-Gotha -- sounded too Germanic. Yes, the name could conceivably change again, though I suspect it won't. When Queen Elizabeth married, the House Name did not change to her husband's surname, Mountbatten.
It remained Windsor. Edit: elsie55 is wrong. The Queen, whose House Name is Windsor, happens to be a direct descendant of the first Stuart monarch of a united England and Scotland and therefore of his ancestors.
She is also a direct descendant of Henry VII Tudor (as was James I Stuart), the Plantagenets through many branches, and of William the Conqueror and back to the Anglo-Saxon monarchs.
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.
