The project The transformation of international law and Norwegian sovereignty in 1814 aimed to examine in new ways, from the perspective of public international law, historical processes in relation to Norway's transition from being one element of the Danish-Norwegian “whole state” to union with Sweden. In order to connect to the international field of research the project has been carried out systematically comparatively and as part of the new trends within the field of history of international law and international relations. The historical premise for this research is the following: The years up to and including 1815 saw the establishment of many of the essential features of modern Scandinavia, including the region's outer borders and new internal constitutional arrangements. These developments occurred within an international legal order undergoing significant change. The Revolutionary and Napoleonic Wars that followed the American (1776) and the French (1789) revolutions were partly the result of – and themselves resulted in – major transformations in public international law, partly summed up at the Congress of Vienna in 1815. The era from the 1770s to 1815 represents one of the most important periods of change in the history of international law.
