History
When The Simpsons went to London on their holidays, Homer hit her carriage with the mini he rented. Because of this, as well as Homer's assumption that she was an imposter due to the initials on her luggage saying "H.R.H." which in his mind meant Henrietta R. Hippo instead of "Her Royal Highness" she sentenced Homer to be imprisoned in the Tower of London and later executed by decapitating him and later placing his head on a spike. After Homer's backfired escape through a secret passage, she later pardons Homer and allows him to leave England after he apologizes, although under the condition that the Simpsons family take Madonna with them when they leave.

The queen and her son Prince Charles enjoyed watching scenes from Springfield through the surveillance cameras planted around the town. She said that Ralph reminds her of Prince Charles.

Titles and Styles
In Scotland she was asked to be styled Elizabeth I of Scotland, since there was no Elizabeth I in Scotland, but there was one in England.
 * April 21, 1926 - November 20, 1947: HRH Princess Elizabeth of York

Trivia
In The Regina Monologues her luggage carried the inscription H.R.H which means Her Royal Highness, which is used for Princes and Princesses, but since she is the Queen, her luggage inscription should have read H.M. as in Her Majesty, because that is her official style, but prior to ascending to the British Throne, she did carry the style Her Royal Highness Princess Elizabeth, Duchess of Edinburgh.
