Nowhere. You mean Norway. People from Norway are Norwegian. I believe this is how you became confused.
This is a long and difficult question, depending if you mean historically in the viking era, or modern Norway. As I assume you mean modern times, Norway got they're independence from Sweden in 1905 almost 100 years after the constitution of Norway was signed in 1814.
"Hallo" or "Hei".
You mean historical?
'norwegian'???? I think you mean 'Norway. The capital city is Oslo. 'Norwegian' is the adjective to describe Norway. .e.g. people speak the norwegian language in Norway.
That depends on if you mean by geography or culture. By geography, Norway is closest to Sweden, but culturally, Norway is probably closer to Denmark.
You mean like the vikings?
It means that the nation Norway owns it.
It means "people from Norway".
If you mean what I think, it would be: Jeg skal til Norge. (I'm going to Norway) 'You are leaving for Norway': 'Du reiser til Norge'
The cross symbolizes Christianity.
It is a dish of meat and potatoes that comes from Norway.
