Treaty of Oliva
The Treaty of Oliva, or Peace of Oliva, was a treaty signed between Sweden and Poland, at Oliva, near Gdansk in Poland, on April 23, 1660. In the treaty John II of Poland renounced his claims to the Swedish Crown, which his father Sigismund III had lost in 1599. In it Poland also formally ceded Livonia and the city of Riga, which had already been under Swedish control since the 1620s.
The treaty finally settled conflicts that had been left standing in the War against Sigismund (1598-1599), Polish-Swedish War (1600-1629) and the Northern Wars (1655-1660) between Sweden and Poland.
