Genuine question Callistemon21, I'm not trying to tee up an argument. We often hear the idea of a slimmed down monarchy - who or what do you have in mind, Monarch + Children + Grandchildren, Monarch + first n in line to the throne, for some value of n...? Or would it be more ‘fluid’? I can see disadvantages to both my suggestions, for the first one some, especially amongst the grandchildren, would become irrelevant. For the second nearly everyone on the list would be ‘demoted’ at some point as they fell further down the line of succession and potential become ‘non-Royal’.
I've no idea how it works in the remaining 6 monarchies (or 11, I think, if you count Principalities and Duchies) in Europe.
Interesting random fact related to Princes/Elected Presidents: the President of France, in this case of course Macron, is one of the two Princes of Andorra, the other being the Bishop of Urgell. Therefore, the Andorran monarchs are in the first case elected by French citizens and in the second place appointed by the Pope.
