Treaty of Oliva

3 May 1660

The Treaty of Oliva was signed near Danzig, now Gdańsk, in a monastery at Oliwa, and it brought the Second Northern War to an end. The parties were Sweden, the Polish–Lithuanian Commonwealth, Brandenburg-Prussia and the Habsburgs, with France mediating. King John II Casimir of Poland renounced his claim to the Swedish throne, and Sweden kept Livonia. The Elector Frederick William of Brandenburg obtained full sovereignty over Ducal Prussia, previously held as a fief from the Polish crown, a step that helped the later rise of the Prussian state. The treaty also protected the religion of Catholics in the territories ceded to Sweden. Sweden was left a leading Baltic power, while the Commonwealth was weakened.
