The SwedishNorwegian War, also known as the Campaign against Norway (Swedish: Flttget 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.

The Convention of Moss (Mossekonvensjonen) was a ceasefire agreement signed on 14 August 1814 between the King of Sweden and the Norwegian government. It followed the Swedish-Norwegian War due to Norway's claim to sovereignty. It also became the de facto peace agreement and formed the basis for the personal union between Sweden and Norway that was established when the Norwegian Storting (Parliament) elected Charles XIII of Sweden as king of Norway on 4 November 1814. The Union lasted until Norway declared its dissolution in 1905.
