The National Romantic style was a Nordic architectural style that was part of the National Romantic movement during the late 19th and early 20th centuries. It is often considered to be a form of Art Nouveau.

Romantic nationalism is the form of nationalism in which the state claims its political legitimacy as an organic consequence of the unity of those it governs. This includes such factors as language, race, ethnicity, culture, religion, and customs of the nation in its primal sense of those who were born within its culture. It can be applied to ethnic nationalism as well as civic nationalism. Romantic nationalism arose in reaction to dynastic or imperial hegemony, which assessed the legitimacy of the state from the top down, emanating from a monarch or other authority, which justified its existence. Such downward-radiating power might ultimately derive from a god or gods (see the divine right of kings and the Mandate of Heaven).
