THO the curation of nationalism by states.

Nationalism is the idea that a person's nation is superior to all others. It is the emergence of a group identity based upon a shared sense of history, cultural, ethnic, or linguistic ties. The difference between nationalism and patriotism is the feeling of superiority; in the eyes of nationalists, loyalty to and pursuing the interests of the nation are more important than anything else. States often curate nationalism by incorporating nationalist ideas in school curriculums, national symbols, monuments, etc.
