Anund Jacob or James, Swedish: Anund Jakob was King of Sweden from 1022 until around 1050. He is believed to have been born on July 25, in either 1008 or 1010 as Jakob. When the Swedish Thing was to elect him the co-ruler of Sweden, the people objected to his non-Scandinavian name. They then gave him the pronomen Anund. The line of kings appended to the Westrogothic law says that he was called Kolbränna ("Coal-burner") as he had the habit of burning down the houses of his opponents.
His political agenda included maintaining the balance of power in Scandinavia, which is why he supported the Norwegian kings Olaf II and Magnus I against Denmark's king Cnut the Great during the 1020s and 1030s. At the Battle of the Helgeå, Anund and Olaf were either victorious over or defeated by Cnut.
When Magnus I became king of Norway and Denmark in 1042, Anund Jakob supported him until the death of Magnus in 1047. Anund Jakob's reign has traditionally been dated from 1022 to approximately 1050, but there is a great uncertainty over the year he died. He was probably alive 1049, and his brother and successor Emund is certain to have ruled Sweden in the summer of 1060.
