From 1397 to 1814, Norway was basically the sidekick in the Kalmar Union with Denmark. Kings ruled from Copenhagen, and Norwegian identity went into hibernation. Think of it as a five-century-long awkward roommate situation.
During this period, the “Kings” were mostly Danish—like Christian IV, who rebuilt Oslo after a fire and left a lot of Renaissance buildings. He’s also famous for having a prosthetic nose after a duel. Royal style tips: Always carry a spare nose.
The 19th century brought a revival, with Norway adopting its own constitution in 1814. They elected Christian Frederick as king, but the Swedes invaded two weeks later. So much for that. Timing is everything.
