The King Charles big Era.
No one knows then?
Does every monarch have an era named after them?
Charles 2 time was known as Carolean. Charles 1 got his head chopped off so didn’t get an adjective.
Henry, Anne, Mary, John, William are a few others without adjectives but are better known for their house names.
I prefer my armed forces to swear allegiance to the Monarch and not the Prime minister. Thatcher would have turned them on the miners.
