"No nation is older than 250"
(i.postimg.cc)
I'm pretty sure the Scandinavian countries are older than counting years with four digits.
To be fair, it's easier to manage a pub than a whole country.
Because the concept of a nation state is not much older, no? American Independence and French Revolution were among the first movements.
Isn't it kinda interesting, that the first nation is still a thing? France is in it's 5th iteration.
