Responding to my own comment because I'm just thinking about this a little more. I think it's very much the reason why God/tradition "appoints the king/queen".

Responding to my own comment because I'm just thinking about this a little more. I think it's very much the reason why God/tradition "appoints the king/queen". - The age old tradition is larger than any individual's life, and theoretically keeps the "dictator" in line (as long as we all respect that tradition). If there is a new period of change with a new leader then anything is possible, subject to human motivations.
