See? You already have to qualify, explain etc. Because it can't be what it says on the box, the last kingdom. History is still in production, so even if at some future point there are no more kingdoms/queendoms and we know which one was the last, it's still possible that in some future someone may have the bright idea again and get away with it.

Just as one can't expect a true and honest answer when asking about a lady's last name. Because she may have another one of those later. There should be a politically rectified way to ask "what's your last name so far?".
