Denmark ceded Norway to the king of Sweden in the Treaty of Kiel, ending the long Denmark–Norway union. Many Norwegians rejected being transferred by treaty and began organizing for self-rule. This agreement set off the political crisis that shaped Norway’s independence movement in 1814.
Norwegian leaders met with Prince Christian Frederik at Eidsvoll and decided to call a Constituent Assembly. The plan was to claim national independence, write a constitution, and choose a king. This meeting helped shift the independence effort from royal inheritance claims to a broader national decision-making process.
Elected representatives gathered at Eidsvoll to draft a constitution for Norway. The assembly debated whether to pursue full independence or accept some form of union with Sweden. These weeks created the institutional foundation for a modern Norwegian state.
The assembly finalized and dated the Norwegian Constitution, declaring Norway an independent kingdom and electing Christian Frederik as king. The constitution limited royal power and created a national parliament (the Storting). It became the key legal document Norwegians later defended within—and eventually beyond—the union with Sweden.
Sweden attacked Norway to enforce the Treaty of Kiel and bring Norway into union under the Swedish crown. The fighting was short but decisive, showing Norway could not secure independence by military means in 1814. The war pushed both sides toward negotiations that recognized Norway’s constitution in modified form.
Norway and Sweden agreed to an armistice at Moss. Sweden accepted that Norway could keep its constitution with changes needed for a union, while Christian Frederik would step aside. This compromise turned a military defeat into a political arrangement that preserved Norway’s internal self-government.
Norway’s Storting adopted constitutional amendments to fit a personal union with Sweden and elected Sweden’s King Charles XIII as king of Norway. Norway kept its own constitution and parliament but shared a monarch and foreign policy with Sweden. This created the Sweden–Norway union framework that lasted until 1905.
Sweden and Norway agreed on the Act of Union (Riksakten), clarifying decision-making between the two states under one monarch. It addressed issues like how the two governments and legislatures would handle shared matters, especially foreign policy. The act helped stabilize the union’s rules, but it did not remove long-term tensions over equality and control.
A union mark combining Swedish and Norwegian colors was introduced into both countries’ flags. The symbol was meant to show partnership and equal status within the personal union. Over time, the mark became controversial in Norway as demands grew for clearer national independence.
After repeated votes, Norway’s parliament overcame royal veto and removed the union mark from Norway’s merchant and state flags (though not the naval ensign at that time). The “pure” Norwegian flag became a visible sign of growing dissatisfaction with the union. The flag dispute showed that constitutional limits on royal power could be used to press for greater Norwegian autonomy.
The Storting passed a bill to create separate Norwegian consulates, aiming to protect Norway’s trade interests abroad. King Oscar II vetoed the bill, reflecting the union’s rule of a shared foreign policy run through Swedish institutions. The veto triggered a constitutional crisis that moved the independence dispute from debate to direct confrontation.
After the king refused to accept the Norwegian government’s resignation and would not form a new government, the Storting declared that the king’s constitutional authority in Norway had effectively ceased. It then proclaimed the union with Sweden dissolved. This was the decisive political break that shifted the question from internal union conflict to international recognition.
Norway held a plebiscite to confirm the Storting’s dissolution decision. The vote was nearly unanimous in favor, strengthening Norway’s negotiating position and showing broad public support. This democratic mandate helped reduce the risk that the crisis would be settled by force.
Sweden and Norway negotiated terms to avoid war and manage practical issues of separation, including border security arrangements. The Karlstad agreement helped turn a tense standoff into an orderly diplomatic settlement. It cleared the way for Sweden’s formal recognition of Norwegian independence later that year.
Sweden recognized Norway as a separate state, and King Oscar II formally renounced his claim to the Norwegian throne. This ended the personal union in legal and symbolic terms. Norway was now independent, but still needed to settle its future form of government and head of state.
After a referendum supported offering the throne to Denmark’s Prince Carl, the Storting offered and he accepted, taking the name Haakon VII. His election and arrival marked Norway’s new start as an independent constitutional monarchy. The 1814 constitution—adapted through the union years—now operated without the union constraints that had driven the 1905 crisis.
