Axel Oxenstierna was born in 1583 and died in 1654. Oxenstierna was Gustavus Adolphus’ most senior nobleman and they formed a formidable partnership together in advancing Sweden’s power in the Baltic. When Gustavus Adolphus died in 1632, Oxenstierna effectively took over the running of the Thirty Years War.
Oxenstierna was a strong supporter of monarchical power. Despite his status as Sweden’s leading nobleman, he did not share the views of other noblemen who viewed an extension of monarchical power as being at their expense. Though he had been responsible for the Accession Charter which the young Gustavus had to sign in 1611, he was a monarchist.
The Treaty of Westphalia is a testament to Sweden’s standing in Europe by 1648. Sweden acquired West Pomerania including Stettin and the Oder Estuary, Wismar in Mecklenburg and the bishoprics of Bremen and Verdun. Sweden also got 5 million thalers from the settlement.
During the regency of Christina, Oxenstierna ruled Sweden. His Regency of Five included one of his brothers and a cousin. This way there was always a majority in the Five who would support Oxenstierna.
In July 1634, Oxenstierna drew up the Form of Government which completely modernised Sweden’s administration. Christina was highly suspicious of this document as she saw it as potentially expanding Oxenstierna’s power at her expense. Christina became convinced that Oxenstierna was taking advantage of her youth and sex.
In 1636, Oxenstierna returned to Sweden from Germany where he had been directing Sweden’s input into the Thirty Years War. It is from this time on that the relationship between Oxenstierna and Christina started to weaken. In 1644, Christina came of age and she started to assert her authority which could only impact the authority Oxenstierna had acquired. As a supporter of monarchical power, he could hardly complain about what Christina was doing. 1644 to 1654 is sometimes referred to as the “Ten Year Rule” – a reference to Christina asserting her authority and making decisions for her country at the expense of Oxenstierna.
The Council’s main concern was that Christina was breaking down the working relationship that had developed when Gustavus was king of Sweden. Oxenstierna believed that her approach might push Sweden towards absolute monarchical rule and that a breakdown in trust would occur. They were also concerned that there was no obvious proof that Charles was a suitable candidate for Sweden’s throne.
Christina knew that if she appeared to be moving towards the lower estates, that would concern the numerically much smaller nobility of Sweden. In 1650, the lower estates via the Diet demanded resumption and also a limitation being put on noble power.
Christina supported this and used this support to get the nobles to agree to her choice of successor. When the nobles agreed to her choice, she returned to their side though a law was passed in 1652 which limited the extra labour a free peasant could do on ex-royal land. However, this was very minor compared to what the nobility had feared could be passed. After this, the normal relationship between crown and nobles was restored. Christina had asserted her power and Oxenstierna had to accept this.
