Pureteenland and Dantura,
The right word for that you want to express (nationalism in sense of believing in supremacy of one's nation or race tha others) is "chauvinist" or "chauvinism".
If you have knowledge about Balkans as you demonstrated the knowledge of words of foreign origin in English...and you obviously have, so bad for Balkans.
