movement solidifies and is threatened by war On 10 February Christian Frederick invited prominent Norwegians to a meeting to be held at his friend Carsten Anker's estate in Eidsvoll to discuss the situation. He informed them of his intent to resist Swedish hegemony and claim the Norwegian crown as his inheritance. But at the emotional session in Eidsvoll on 16 February, his advisors convinced him that Norway's claim to independence should rather be based on the principle of self-determination and that he should act as a regent for the time being.
