My question is how do we bring back monarchies to nations with no dynastic heirs. An example of which is Poland, my nation of birth. We had a hereditary monarchy, ruled by the Piasts up until the Jagiełło dynasty and then once the PLC came to be, it was changed to an elective monarchy. The problem is that if it were to be reverted to hereditary rule, well, there aren't any actual linear 'descendants' of the Piast royal family beyond the usual 'everybody is partially descendant from dynasty X or Y, and elective monarchy has fucked Poland before; it is an abomination of the idea of a monarchy.
So, in that case, what should be done? Would the leader of a monarchist faction, regardless of their background be chosen and start a new legacy and dynasty? After all, the royal dynasties had to start like that, they didn't always exist. I, for example, to my knowledge, come from no great house, but if I were to say, lead a faction or party that gained control over Poland, would my claim to the throne be any less valid than someone's from a more.. prestigious family who hasn't bothered to return the nation to its natural state?
