The 'Kalmar Union' (
Danish,
Norwegian and
Swedish: ''Kalmarunionen'') was a series of
personal unions (
1397–
1524) that united the three kingdoms of
Denmark,
Norway (with
Iceland and
Greenland) and
Sweden (including some of
Finland) under a single
monarch.
[1] The countries had given up their
sovereignty, but not their
independence, and diverging interests (especially Swedish nobility's dissatisfaction over the dominant role played by Denmark and
Holstein) gave rise to a conflict that would hamper it from the
1430s until the union's breakup in
1523 when
Gustav Vasa became king of Sweden. The union was formally dissolved the following year. Norway and her overseas dependencies, however, continued to remain a part of the realm of
Denmark-Norway under the
Oldenburg dynasty for several centuries after the dissolution.
Union
The union was the work of Queen
Margaret of
Norway (
1353–
1412), a daughter of King
Valdemar IV of
Denmark. At the age of ten, she was married to King
Haakon VI of Norway. Margaret succeeded in having their son
Olav recognized as heir to the throne of Denmark. In
1376 Olav inherited the crown of Denmark from his maternal grandfather as King
Oluf III, with his mother as guardian. When Haakon VI died in
1380, Olav also inherited the crown of Norway. The two kingdoms were united in a personal union under a child king, with the king's mother as his guardian.
Before Olav came of age and could take over the government, he died in
1387. Margaret made the Danish Council of the Realm elect her as regent of Denmark, but she could not assume the title of queen. Next year she was also recognized as regent of Norway, on
February 2,
1388. She adopted her sister's grandson Bogislav, a son of prince Vartislav of
Pomerania, and gave him the more Nordic name Erik. She manoeuvred to have the Norwegian Council recognize him as heir to the throne of Norway
[2], in spite of his not being first in the line of succession, and he was installed as king of Norway in
1389, still with Margaret as his guardian.
In Sweden, this was a time of conflict between king
Albert of Mecklenburg and leaders of the nobility. Albrecht's enemies in
1388 elected Margaret as regent in the parts of Sweden that they controlled, and promised her assistance in conquering the rest of the country. Their common enemy was the
Hanseatic league and the growing German influence over the Scandinavian economy.
[3] After Danish and Swedish troops in
1389 defeated the Swedish king,
Albert of Mecklenburg, and he subsequently failed to pay the required
tribute of 60,000 silver
marks within three years after his release
[2], her position in Sweden was secured. The three Nordic kingdoms were united under a common regent. Margaret promised to protect the political influence and privileges of the nobility under the union. Her grandnephew Erik, already king of Norway since 1389, succeeded to the thrones of Denmark and Sweden in
1396.

Eric of Pomerania
The Nordic union was formalized on
June 17 1397 by the
Treaty of Kalmar, signed in the Swedish castle of
Kalmar, close to the Danish border. The treaty stipulated an eternal union of the three realms under one king, who was to be chosen among the sons of the deceased king. They were to be governed separately, together with the respective councils, and according to their ancient laws, but foreign policy was to be conducted by the king. At Kalmar, the 15 year old
Eric of Pomerania {right} was crowned king of all three kingdoms by the archbishops of Denmark and Sweden, but Margaret managed to remain in control until her death in 1412.
Conflict
The Swedes were not happy with the Danes' frequent wars on
Schleswig,
Holstein,
Mecklenburg, and
Pomerania, which were a disturbance to Swedish exports (notably
iron) to the
Continent. Furthermore, the centralization of government in Denmark raised suspicions. The
Swedish Privy Council wanted to retain a fair degree of
self-government. The unity of the union eroded in the
1430s, even to the point of armed rebellion (the
Engelbrecht rebellion), leading to the expulsion of Danish forces from Sweden. Erik was deposed (
1438–
39) as the union king and was succeeded by the childless
Christopher of Bavaria. In the power vacuum that arose following Christopher's death (
1448), Sweden elected
Charles VIII king with the intent to reestablish the union under a Swedish crown. Charles was elected king of Norway in the following year, but the
counts of
Holstein were more influential than the Swedes and the Norwegians together, and made the
Danish Privy Council appoint
Christian I of
Oldenburg as king. During the next seven decades struggle for power and the wars between Sweden and Denmark would dominate the union.
After the successful reconquest of Sweden by
Christian II and the subsequent
Stockholm bloodbath in
1520, the Swedes started yet another rebellion which ousted the Danish forces once again in
1521. While independence had been reclaimed the election of King
Gustav of the
Vasa on
June 6,
1523, restored sovereignty for Sweden and dissolved the union. The day of Gustav Vasa's crowning is since
1983 the
National Day of Sweden, but was only recently made a
national holiday, in
2005 (482 years later).
Final dissolution
The last structures of the Kalmar Union remained until
1536 when the
Danish Privy Council, in the aftermath of a civil war, unilaterally declared Norway to be a Danish province
[5], without consulting their Norwegian colleagues. Norway kept some separate institutions and its legal system
5, but the former Norwegian possessions of
Iceland,
Greenland, and the
Faroe Islands, came directly under the Danish crown. In the
1814 treaty of Kiel, the king of
Denmark-Norway was forced to cede Norway to the
king of Sweden,
Charles XIII. Norway, led by the vice-roy, prince
Christian Frederik, objected to the terms of the treaty. A constitutional assembly declared Norwegian independence, adopted a liberal constitution, and elected Christian Frederik king. After a brief war with Sweden, however, the peace terms of the
Convention of Moss recognized Norwegian independence, but forced Norway to accept a personal union with Sweden.
In the middle of the
19th century, many intellectuals joined the
Scandinavist movement, which promoted closer contacts between the three countries. At the time, the
union between Sweden and Norway under one monarch, together with the fact that King
Frederik VII of Denmark had no male heir, gave rise to the idea of reuniting the countries of the Kalmar Union, except
Finland.
