The Swedish-Norwegian War begins.
The Swedish–Norwegian War, also known as the Campaign against Norway (Swedish: Fälttåget mot Norge), War with Sweden 1814 (Norwegian: Krigen med Sverige 1814), or the Norwegian War of Independence, was a war fought between Sweden and Norway in the summer of 1814. The war resulted in a compromise, with Norway being forced into the United Kingdoms of Sweden and Norway, a union with Sweden under the Swedish king Charles XIII, but with Norway having its own constitution and parliament.
