Sweden-Norwayball, also known as Sweden and Norwayball, the United Kingdomsball, and officially, the United Kingdom of Sweden and Norwayball, was a union between the kingdoms of Swedenball and Norwayball.
Sweden had lost the Great Northern War. He lost Finland, and for a compromise, he looked west.
On 7 January 1814, Denmarkball, about to be overrun by Swedenball, Russiaball, and Prussiaball troops under the command of the elected crown prince of Sweden, Denmarkball agreed to cede Norwayball to the Swedenball in order to avoid an occupation of Jutland.
Of course for the newly independent Norwayball, an organised resistance was impossible and Swedenball's troops quickly occupied most of Norway. The war ended with decisive Swedenball victory and two countries were united under Kingdom of Sweden-Norwayball.
After almost a century of uneventful peace, the union dissolved after heavy disagreements between Norwayball and Swedenball.
