The Polish–Swedish War (1621–25) was another war in the series of conflicts between the Polish–Lithuanian Commonwealth and the Swedish Empire (see Polish–Swedish wars). It began with a Swedish invasion of Polish-Lithuanian fief of Livonia. Swedish forces succeeded in taking the city of Riga after a siege. The Commonwealth, occupied by a serious war with Ottoman Empire (battles of Cecora and Chocim) was unable to send significant forces to stop Gustav Adolf, and was forced to sign a truce favorable to Sweden. The Commonwealth was forced to cede Livonia north of the Dvina (Düna) river, and retained only a nominal control over Riga. A new truce in Mitau (Jelgava, Mitawa) was signed and lasted from November 1622 to March 1625.
