War against Sigismund
The war against Sigismund () was a war between Duke Charles, later King Charles IX and Sigismund, King of Sweden and the Polish–Lithuanian Commonwealth. Lasting from 1598 to 1599, it is also called the War of Deposition against Sigismund, since the focus of the conflict was the attempt to depose the latter from the throne of Sweden. The war eventually resulted in the deposition of Sigismund (with Duke Charles taking over the government and later also acceding to the throne), the dissolution of the Polish-Swedish Union, and the beginning of an eleven-year war.
