I suspect DUpipo, and many others, are equating Nazism or Fascism with nationalism. Nationalism predates both by at least a century. From what little I've seen the aftermath of the Napoleonic War (e.g. the Congress of Vienna) kind of wakened nationalism in EuroLand, with vary degrees of consequences for the Ottoman, Russian, and Austro-Hungarian Empires. Examples would be the war for Greek independence, the Balkans more or less rebelling against the Ottoman and Austro-Hungarian Empires, Zionism, Prussia engineering the unification of Germany (and the twisted road to get there), and the unification of Italy. Nationalism also drove Japan's rise to power and the consequent First Sino-Japanese War and Russo-Japanese War, and the Boxer Rebellion. Then there's all the colonies that gained independence post-WW2. Not only is nationalism not peculiarly Nazi or Fascist, it's not even solely European.
