Charles IX of Sweden - King Charles IX

King Charles IX

Finally, the Riksdag at Linköping, 24 February 1600 declared that Sigismund abdicated the Swedish throne, that duke Charles was recognized as the sovereign. He was declared king as Karl IX (anglicized as Charles IX). Charles's short reign was one of uninterrupted warfare. The hostility of Poland and the breakup of Russia involved him in overseas contests for the possession of Livonia and Ingria, the Polish–Swedish War (1600–1611) and the Ingrian War, while his pretensions to claim Lappland brought upon him a war with Denmark in the last year of his reign.

In all these struggles, he was more or less unsuccessful, owing partly to the fact that he and his forces had to oppose superior generals (e.g. Jan Karol Chodkiewicz and Christian IV of Denmark) and partly to sheer ill-luck. Compared with his foreign policy, the domestic policy of Charles IX was comparatively unimportant. It aimed at confirming and supplementing what had already been done during his regency. He did not officially become king until 22 March 1604. The first deed in which the title appears is dated 20 March 1604; but he was not crowned until 15 March 1607.
