Sønner av Norge

"Sønner av Norge" (originally "Sønner af Norge", lit. '"Sons of Norway"') is the common title of the song "Norsk Nationalsang" (lit. '"Norwegian National Song"'), which was the de facto national anthem of Norway from 1820 until the early 20th century. From the mid-1860s, "Ja, vi elsker dette landet" gradually came to occupy the unofficial position as national anthem, but was used alongside "Sønner af Norge" until the early 20th century, with "Sønner af Norge" being preferred in official situations.

History
The lyrics were written by Henrik Anker Bjerregaard (1792–1842) and the melody by Christian Blom (1782–1861), after the Royal Norwegian Society for Development had announced a competition to write a national anthem for Norway in 1819. "Norsk Nationalsang" ("Sønner af Norge") was announced as the winner.
