Hi Cleopatra:
Nation is a community
constituted by shared belief and mutual commitment.
extended in history
connected to a specific land
distinguished by other communities by its public culture.
I would add "shares a set of national myths".
...for example in medieval universities it was used to classify students by country of origin ...
It was also used this way amongst the Knights of Malta, where it caused all sorts of problems in co-ordinating the defence against the Ottomans. Rioting between the different "nations" of the Paris universities was almost a recognised sport. Give young men some means of dividing themselves into "teams" and inter-team violence follows. Patriotism, like religion, is one of the ways older minds manipulate young male violence to their own ends.
In the silly poem that I quoted above to tease Capel Dodger , the word “nation” is applied to Romans,Saxons, Danes and Normans and to people that he ironically identifies as those who contributed to the “heterogeneous things , an Englishman”.
Eddie Izzard recently presented a series called "Mongrol Nation" about Britain, I recommend it (I'm a big fan anyway). You'll recall I did mention "Britain (a whole argument in itself)" earlier on. Fortescue was wrong about Scotland being a "nation", but right not to think that Wales was (never was, still isn't).
So, it’s wrong to sugget that the concept of Nation entered politics with the rise of the 19th ce Nationalism it was already recognizable to places at least a century earlier.
Indeed, but it was a tool of philosophy rather than a dominant political reality. The theorising that led to 19thCE Nationalism - which is politically dominant today - was part of an attempt to create an alternative ideology to the heriditary, "Mandate of Heaven" ideology that was holding back progress in Germany. (Socialism, which is explicitly anti-nationalist, was another such effort.) The finished product was taken up by subjects of the Austrian Empire, despite it being mostly inappropriate (Hungary, at least, excepted). Spain, France and Portugal were "natural", peripheral nations that coalesced in the late 15th/early 16thCE (post-1492 in Spain, post Louis XI in France, every now and again in Portugal). There was no precise theory of nation leading the way. It was these examples which theorists of nationalism looked to for their defined ideology, without, perhaps, recognising their real nature. And it this model which has been imposed on the world outside Western Europe (where your examples come from). That's what I see as the problem.
The Greeks were the first who distinguished themselves from the "barbarians".
...I don't doubt the antiquity of the Chinese civilization I am just saying that the Greeks were the first that they not only perceived but expressed in their writings and turned into a policy the idea that they differ as a group from the people that surrounded them.
You do make some wild claims. I doubt that the Sumerians missed this idea, or the early Chinese. Ezra was pushing the idea of at least a religious nation when he banned marrying-out. The Greeks happen to have been particularly well-reported, and we can see from those reports that nationalism was only ever the preferred ideology of the dominant city of the time. Writing the idea down and having those writings still extant is hardly relevant.
The idea that each people had a homeland and that the rule of foreigners constitute oppression that must be resisted gives us the right to suggest that this first form of nationalism has political implications and goes far beyong the triban sentiment and feeling.
Actually, the Greeks had the idea that
they had a homeland. Alexander took to the idea of Empire - with Greece as part of it - without any hesitation, as did the Seleucids and your Ptolomaic ancestors. Rule of foreigners as appression ... I imagine the problem wasn't thought about much, them being Greeks and all.
Berlin says that those who view politics as an activity that should be left in the hands of the elite view with distaste the philosophy on which sovereign nations are built.
In modern terms, such people are eager to grasp the ideology, since it gives them cover for exercising their rapacity within their own borders. The outside world, dazzled by the idea of "sovereignty" that must not be denied, leaves them to it. "Nations" sprang up all over Central America post-Empire, ruled by just that type. The 1880's have been described as the decadde when nationalism completed its migration fro left (democratic) to right (demagogic).
Think about it Capel Dodger and do not reject Berlin because the man was not a Zionist.
I don't dismiss anyone because a label has been stuck on them. It is my ambition to be right, not to have any prejudices confirmed. I won't achieve that by rejecting useful thinking, and even erroneous thinking can be stimulating.
Edited to add:
I'm assuming Ptolemaic descent from your avatar, but apologies if you're referring to Cleopatra mother of Herod Philip.
