The Danish nation is a concept closely connected to 19th century ethnic nationalism. It relates to self-identification rather than to laws. The term's use is relevant chiefly in historical contexts of debate on the status of Schleswig and Holstein vis-à-vis a Danish nation-state.
The Danish nation is to be distinguished from the legal concept of nationality, Danish nationals; i.e. persons fully subjected to Danish law.
The Danish nation consists, in theory, of all people the other members see as members.
