Nation state has been around since the agricultural revolution

Except it hasn't.

Name one.

Egypt

LMAO

China

Terrible example, because it's false.

China???????

Those are not nation states.

Persia

wtffff

these are all nation states

Stop, let me address how you're wrong one at a time.

they have an authority and border

Egypt's identity was religious and shifted through time, the nation was embodied by the dynasty.

no

Persia really has no national identity.

Yes. You are simply blatantly wrong.

those are or where nations

Persia was routinely conquered by foreign entities.

routinely

no

There was no national identity to speak of.

Yes, routinely.

Muh nations came around in 1850

no thats not a thing

Jalayirids, Mongols, Gokturks, Oghuzi Turks, Scythians.

Persia has repeatedly been conquered.

look at european empires

they had nationalism for as long as they where around

look at mercantilism

Mercantilism was based on the acquirement of resources.

Has nothing to do with nationalism.

How about we start by you defining what a nation state is because it clearly is not what an actual nation state is if you think Persia and Egypt and China were nation states.

France was not even a nation before the French Revolution. It was numerous languages and *communal* cultures. People did not speak "French" outside of the Ile-de-France.

Same thing in China.

Mandarin, the word itself, refers to the court language of the Qing dynasty. People did not speak Mandarin. There were various local languages. Same as France.

There was no national identity to speak of.

You are simply historically incorrect on this.

The word Mandarin literally comes from the Portuguese word for minister.

Egypt did not really have a collective identity until the Muslim conquests, and thereafter it had a religious identity just like European states did until the erosion of that form of identity by the Westphalian system and the secularization of Europe by liberalism in the 18th and 19th centuries, giving birth to actual ethnolinguistic identities.
