With the victory of the Coalition (Tsardom of Russia and the Kingdom of Denmark-Norway) and the defeat of Sweden prompted a change in the politics and territories of the Scandinavian countries. Besides Sweden being bankrupt and throw in political chaos, Denmark-Norway was exhausted after the war and worried at the threat of Prussian and its ambitions to control the Baltic Sea and the duchies of Schleswig and Holstein.

Political institutions of the United Kingdom
The United Kingdom was initially established as the personal union of Denmark-Norway and Sweden. Originally Denmark-Norway and Sweden had separate legal codes and currencies, and mostly separate governing institutions (Estates and councils of the realm). Each one was administered by a governor-general named by the King. Following the introduction of absolutism, the centralisation of government meant a concentration of institutions in Copenhagen and the abolishment of any institution outside the rule of the king and all high office came to be named and responsible to the King.

When the dynastic succession and internal revolts of the nobles in the three counties would force, against the wishes of King to re summoned and grant more power to the Estates of the three kingdoms in exchange of hereditary crown, rescinding the established custom of an elective monarchy and revive the councils of the Realm of each kingdom ,

The progress towards a unitary state would come possible on a later date. The European revolutionary wars pushed for greater centralization and the reestablishment of the governing councils and states of each of the constituent kingdoms toward a more centralized organization: King, Grand Council of the Ream, the central ministries and the Estates of the three kingdoms.

However the revolutionary wars also came to the United Kingdom when a French and German republican armies and navies occupied Copenhagen (the Battles of Holstein and Jutland) obligating the King and his court to flee towards Oslo and shipped to Britain. Meanwhile the revolutionaries proclaimed the Republic of Scandinavia.
