"Ja, vi elsker dette landet" is the Norwegian national anthem. Originally a patriotic song, it came to be commonly regarded as the de facto national anthem of Norway in the early 20th century, after being used alongside "Sønner av Norge" since the 1860s. It was officially adopted in 2019.

He rose to the rank of vice-admiral for his services in the Great Northern War. Born in the Norwegian city of Trondheim, Peter Wessel travelled to Copenhagen in 1704 and eventually enlisted in the navy.
