Charles I tried to make himself closer to an absolute monarch, but that didn’t end well. Charles II restored royalty following he Puritans. They were both heroes for royal power, which might be why that name was chosen 70 years ago.
That being said, Charles III is such a jerk, and should abdicate. William V would make a much better king.
Why do you think he would be a good king? He’s still an inbred with two idiots for parents. Charles and William are both secret Muslims, right? Which one dressed as a Nazi?
