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.
