When did Norway become free from Sweden?

Norway became free from Sweden in 1905 following a peaceful dissolution of the union between the two countries. The union between Norway and Sweden had lasted for 91 years prior to this, starting in 1814 after the Napoleonic Wars. However, as time went on, growing tensions between the two nations led to an increasing desire for Norwegian independence. Ultimately, a referendum in 1905 resulted in a majority of Norwegians voting for independence, leading to the dissolution of the union and the creation of the sovereign Kingdom of Norway.
