The Svalbard Treaty was signed in Paris on 9 February 1920.
The treaty establishes Norway’s full and undivided sovereignty over Svalbard. Svalbard is part of the Kingdom of Norway, and it is Norway that ratifies and enforces the legislation that is to apply to the archipelago. Nevertheless, the treaty does include some conditions restricting the enactment of Norwegian sovereignty, and Norwegian authorities are required to see to it that Norwegian legislation and administration respect these conditions.
The 8 Arctic States are all parties to the treaty.
