Should the Monarchies of Poland and Lithuania be Restored, ...

... who would be the logical heirs to those thrones?

I can only repeat it would be most likely return to Habsburgs in CZ, even though we never really liked them. But our only national dynasty (the legal branch) extinct in 1306

well, it would be totally hard to find the real heirs to the throne in Poland, as since the 16th century we had elections and elected kings - there were no such thing as a succession from the father to the son, so that would be really hard to find a proper king for us now

and still, I don't think my compatriots would like to have a king now... well, I personally wouldn't mind at all, but I think that my country is now occupied with more important things than the restoration of the monarchy, like the economy, finances of the country... I think the government wouldn't like to spend even a little złoty (our currency) on finding and introducing the new king to every little aspect of the rule...
