Thanks to all who attempted my sovereign quiz. There were some very good answers, but as NER readers should know by now, quizzes are as much about reading the author's mind as they are about objective right and wrong. My mind is in many ways very nerdy, as you will see.

Here is a reminder of the quiz:

Which of the following monarchs is the odd one out and why? (Be careful.)

1. Queen Elizabeth I
2. Queen Anne
3. Queen Victoria
4. King George III
5. King Richard I

The answer is King George III.

George III was mad, as we know. He began one of his speeches "My Lords and Peacocks." Arguably he didn't know much. But unlike the other monarchs listed, he knew his number.

Queen Elizabeth I didn't know she was Queen Elizabeth I. She knew she was Queen Elizabeth, but she wasn't to know that there would be a second one. Queens Anne and Victoria, likewise didn't know - and we still don't know - whether they are the first of several or the one and only. King Richard "Gare de Lyon" knew his station, but he didn't know he whether he was King Richard I or just plain old King Richard.

George III, alone in that list, knew he was George III and would be no matter how many Georges came after him.

People say that there were two World Wars - World War I and World War II. But I think there was only one - World War II.
