Abstract :
Over the last four decades, Norwegian rule on the Svalbard islands has developed gradually, from being virtually non-existent to firm. This study explains these developments in Norwegian jurisdiction both from a perspective of international relations and within a paradigm of domestic politics. It finds that external forces have been the permissive causes of change, while internal forces represent the efficient causes. Norway’s incremental strengthening of jurisdiction, notably from the mid-1970s onward, has resulted in an unprecedented Norwegian grip on the Arctic islands in which the other parties to the 1920 Svalbard Treaty seemingly acquiesce.
