This is a very good list, although it has some problems.
There is no particular compelling argument that the Dutch republic was the "first" nation-state (France? England? Muscovy?), especially when the concept of a "nation" at the time was, uh, not the same as ours. Hell, the most traditional and widely-spread nationalism narrative is that it didn't exist in a recognizable form until the Enlightenment, and if any state were to be the first "nation-state" in Europe it would be France.
That is wrong. There was nationalism since Ancient times, mainly in Greece and Rome. The Greeks considered Barbarians all non Greeks. That is not something strange. The strange thing is that there was not a unified Greek State (at least until Alexander, and even that was not a complete unification. The Spartans never joined the League of Corinth. Also it collapsed after the death of Alexander) and yet there was a nationalism based on common culture. Also Aristotle said to Alexander ''Rule the Greeks as a ruler and the Barbarians as a Despot''. If this is not nationalist (and racist), then I dont know what it is.
Also there was a Roman Nationalism for sometime, until the Romans created the Roman Empire. From there on, the Romans created a huge multi cultural empire (Like USA, but with an Emperor).
After the collapse of Rome, a strong regionalism existed because of fedualism, in western Europe at least. The Byzantine Empire was a multicultural Empire united under a strong Monarchy, christianity and Hellenic language (Language, not nationality. Something like English in USA). However, as it lost land, a nationalistic movement was born, but it died only a few years after it was born. In 1453 the Ottomans took over Constantinople.
The creation of huge Empires (Ottoman, Holy Roman, Spanish) ceased those nationalistic movements.
The Dutch revolution, although religious, created a state that was homeland to a certain ethnic group, the Dutch. So the Dutch were the first
modern Nation State.
France was not a nation state until the French Revolution. Until that day, the French were subjects of the King of France. After the Revolution, they were free citizens of France. That's why nationalism developed. If you think that this is wrong, explain me why nationalism developed so fast after the campaigns of Napoleon.
Another example: Why China, a country with so rich history, never developed a strong nationalism until the creation of the Republic? Why a state that existed for almost 3,000 years did not develop nationalism, like the Ancient Greece? One of the many reasons is that it was an absolute monarchy. If it became a constitutional Monarchy, then, maybe, there would have been a stronger Nationalism in China. It is true that the Chinese also considered the non-Chinese Barbarians, but there was not a strong nationalistic sense in China. Other thing is nationalism and other Patriotism.
In the Ottoman Empire, because of the religious divisions and because the Patriarch was the one that was responsible for the taxes of the Christians and because of the regional Governments (each village - town elected its own ''Governor'' [The Greek Dimogerontes, for example]), Nationalism deveoped very fast although it was an absolute Monarchy.
Then Communism came and once again a huge multicultural Empire was created, the Soviet Union. However, it also failed and after 80 years it collapsed. After its collapse, strong nationalistic movements developed in the former USSR states.
So since the start of history, there were two movements: Nationalism and Multiculturalism. Saying that nationalism is something modern is wrong. Since the Ancient times there was a fight between nationalism and multiculturalism. There was nationalism in Ancient Greece and Rome, but after the conquests of Rome, a huge multicultural Empire was developed. A few years after the fall of Rome, huge multicultural Empires were created. However after Napoleons campaigns, in less than a century Empire's that lasted more than 500 years collapsed. Communism managed to create a huge multicultural Empire, but after its fall it's multiculturalism collapsed and a strong movement of nationalism was born in the former USSR states.
So saying that Nationalism is something modern is wrong. Also saying that the first Nation State is France is wrong.
