The 'Convention of Moss' was a cease fire agreement, signed
August 14,
1814, between the Swedish King and the
Norwegian Storting. It followed a brief
Swedish campaign against Norway due to Norway's claim to sovereignty. It also became the ''de facto'' peace agreement and formed the basis for the
personal union between Sweden and Norway that lasted until Norway
declared the dissolution of the union in
1905.
In 1814,
Denmark-Norway was on the losing side in the
Napoleonic wars. On
January 14, 1814, at the
Treaty of Kiel, Norway was ceded to the king of Sweden. In an attempt to take control of its destiny the Norwegians convened a
constitutional assembly at
Eidsvoll and on
May 17 1814 signed the
Constitution of Norway. The vice-roy and heir to the thrones of Denmark and Norway, prince
Christian Frederik, was elected by the assembly as king.
The Swedish king,
Karl XIII rejected the premise of an independent Norway and launched a military campaign on
July 27, 1814 with an attack on the
Hvaler islands and the city of
Fredrikstad. The Swedish army was superior in numbers, was better equipped and trained, and was led by one of Napoleon's foremost generals, the newly elected Swedish crown prince,
Jean Baptiste Bernadotte. Battles were short and decisively won by the Swedes. Armistice negotiations concluded at
Moss on August 14, 1814.
In the peace negotiations, Christian Frederik agreed to relinquish claims to the Norwegian crown and return to Denmark if Sweden would accept the
democratic Norwegian constitution and a
loose personal union. The convention comprised four documents, all written in French, with the following main points:
★ The agreement was entered into between the Swedish crown prince on behalf of the Swedish King, and the Norwegian parliament. The Swedes did not recognize Christian Frederik's claim to the Norwegian throne, so he was not a party to the official agreement. (Though a secret agreement was also executed ordering him to return to Denmark).
★ The Norwegian parliament was to convene by the end of September, or the beginning of October, to ratify the convention.
★ The King of Sweden accepted the Norwegian constitution, with only such amendments as were necessary to accommodate the union with Sweden. All changes were to be accepted by the Norwegian parliament.
★ Christian Frederik should abandon all claims to the Norwegian crown and leave Norway.

The Moss Ironworks main office - where the Convention of Moss was negotiated and signed.
Norwegians were shocked by their government's concessions, and when the Swedish general
Magnus Björnstjerna, who had led the Swedish negotiations, arrived in
Christiania, he got an unfriendly welcome. Norwegians also directed their resentment toward their own leaders and what they perceived as spineless military defense. Over time, public opinion shifted. The convention was a significant improvement over the terms dictated to Denmark-Norway at the treaty of Kiel. Notably, Norway was no longer to be treated as a Swedish conquest but rather as an equal party in a union of two independent states. Both the principle and substance of the Norwegian Constitution were accepted, and Norway retained its own parliament and separate institutions, except for the common king and foreign service. This was the last war between Sweden and Norway, and Sweden's last war.
