The war against Sigismund (Swedish: Kriget mot Sigismund) was a war between Duke Charles, later known as King Charles IX of Sweden, and Sigismund, who was at the time the king of both Sweden and the Polish–Lithuanian Commonwealth (that is, the King of Poland and the Grand Duke of Lithuania). 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.
