Kalmar Union

The Kalmar Union was a special agreement made in Scandinavia at a place called Kalmar in Sweden. It was created by Queen Margaret of Denmark. From 1397 to 1523, this union brought together three big kingdoms under one ruler: Denmark, Sweden (which at that time also included much of today’s Finland), and Norway. Norway also included islands and areas like Iceland, Greenland, the Faroe Islands, and the Northern Isles of Orkney and Shetland.

Even though these lands shared the same monarch, they were still their own separate countries with their own laws. But they worked together on important decisions both inside and outside their borders. The union did not last perfectly without breaks; it had a few short pauses along the way.

In 1523, a man named Gustav Vasa was chosen to be the King of Sweden. Eleven days after he became king, he entered the city of Stockholm, and Sweden decided to leave the Kalmar Union. A year later, in 1524, the king of Denmark officially gave up his right to rule Sweden with the Treaty of Malmö.

History

The Kalmar Union was formed by Scandinavian leaders who wanted to be stronger against powerful trade groups like the Hanseatic League. Queen Margaret I of Denmark helped create the union. She brought Denmark, Sweden (which included parts of modern-day Finland), and Norway together under one ruler. The union started in 1397 when Margaret’s adopted son, Eric, became king in Kalmar.

The union had many problems. Different groups in the countries often disagreed. Over time, Sweden left the union. In 1523, Gustav Vasa led Sweden to independence, ending the Kalmar Union. Denmark and Norway stayed connected for many years. Norway later joined Sweden in 1814 before becoming fully independent.
