> A nation is a community of people with a common culture, language, ethnicity
Nitpick: The belief of the existence of the said common ground is actually more important than its actual existence. France is considered a nation state even though there are several ethno-linguistic groups in France. A few illustrations:
- less than half of the French population during the French revolution spoke French as their native language.[1]
- The second Nobel Prize of Literature from France (Frédéric Mistral) didn't wrote its work in French, but in Occitan[2].
- My family has lived in France for as long as genealogy could trace back, yet half of my great-grandparents only learnt French in school, they didn't spoke it at home.
[1]: I don't have an online source for that, nor the exact figure: I read it in Frernad Braudel's L’Identité de la France
