Treaty of Kiel As early as in 1812, prior to the
Napoleonic invasion of Russia, the Swedish Crown Prince
Charles John (Karl Johan) – formerly
Marshal of France Jean Baptiste Bernadotte – had entered into an agreement with Tsar
Alexander I that
Russia would support a Swedish attack on Norway in order to force
Denmark–Norway to cede its northern part to Sweden. The Swedish attack against Norway was postponed however, due to the fluid state of the conflict between
Napoleon and the
Sixth Coalition. The
Swedish Army and, incidentally, Karl Johan's skills as a general, were urgently needed against
France in
Central Europe. On 18 May 1813, Swedish troops re-occupied
Swedish Pomerania and deployed against Napoleon's forces as a result of treaties between Karl Johan (on behalf of Sweden),
Great Britain and
Prussia, which ceded Norway to Sweden for its participation in the war, becoming effective after France and its allies (including Denmark–Norway) were defeated. In early December, Karl Johan led an invasion of Denmark with his Allied Army of the North that included Swedes, Russians and North Germans. The Danes were outnumbered and were unable to mount a coherent defense against Karl Johan's battle-hardened army. Within a few days, the Danes were forced out of
Holstein and into Jutland proper. By 14 December, Bernadotte agreed to an armistice and peace talks began in
Kiel on the basis of ceding Norway to the Swedish king in return for Swedish Pomerania, additional territory in North Germany, specifics to be decided at the general peace conference following the cessation of hostilities between the Sixth Coalition and Imperial France, as well as 1,000,000
Riksdalers. The Danish position was hopeless and by early January 1814, King
Frederick VI of Denmark–Norway reconciled himself to the necessity of losing Norway. By the
Treaty of Kiel, signed on 13 January, King Frederick VI had to cede the Kingdom of Norway to the king of Sweden, by which the two nations would enter a union. However, this treaty was not accepted by the Norwegian people, who refused to be simply a bargaining chip. Elements of the Danish government also covertly supported Norway's determination for independence. Ultimately, Denmark would pay a catastrophic price for the treaty, as Karl Johan viewed this support, no matter how covert, as betrayal and a violation of the treaty, and this would later be reflected in the final peace settlement at the
Congress of Vienna, which voided Kiel's promise to compensate Denmark for its loss of Norway with Swedish Pomerania, various additional Northern German territory, and 1,000,000 Riksdalers.
Norwegian Constituent Assembly An insurrection broke out, led by Prince
Christian Frederick of Denmark,
heir presumptive to the thrones of Denmark and Norway and
Governor-general of Norway (and later King Christian VIII of Denmark). He gathered a constitutional assembly which adopted the liberal constitution of 17 May, with that constitution also naming Christian Frederick as king of an independent Norway. As the head of the new state, Christian Frederick desperately tried to gain support from the United Kingdom, or any of the other major powers within the
Sixth Coalition, in order to maintain Norway's independence. However, the foreign diplomats, more concerned with Napoleon, refused to promise any outside support to the Norwegians. ==Armies==
