Treaty of Plussa

The Treaty or Truce of Plussa, Pljussa, Plyussa or Narva and Plusa (Плюсское перемирие, Stilleståndsfördrag vid Narva å och Plusa) was a truce between Russia and Sweden, which ended the Livonian War (1558-1583). The truce was signed on 10 August 1583 at the Plyussa River north of the city of Pskov. The truce was set to expire in 1586, but extended in 1585-1586.

According to this truce, Sweden kept the annexed Russian towns of Ivangorod (Ivanslott), Jamburg, Koporye (Kaprio), and Korela (Kexholm/Käkisalmi) with their uyezds, holding control over Ingria. Russia kept a narrow passage to the Baltic Sea at the estuary of the Neva River, between the rivers of Strelka and Sestra.

Upon the expiration of the truce in 1590, Russia resumed the war against Sweden to once again conquer Narva and other Baltic lands annexed by the Swedes. Beginning in 1593, Russia and Sweden resumed peace negotiations, which would last for two years. Finally, the two countries signed the Treaty of Teusina (Tyavzino) in 1595, where Russia regained the territories lost in 1583.

Sweden regained control over Ingria by the Treaty of Stolbovo in 1617, following the Ingrian War.
