Treaty of Teusina

The Treaty of Teusina (Finnish: Täyssinän rauha, Russian: Тя́взинский ми́рный догово́р) was concluded by Russian diplomats under the boyar Afanasiy Pushkin and ambassadors of the Swedish king at the village of Tyavzino [ru] (Finnish: Täyssinä, Swedish: Teusina) in Ingria on 18 May 1595 to end the Russo-Swedish War (1590–1595).

The Swedish-Russian border was delineated from the outstream of the Systerbäck river into the Gulf of Finland, over the lakes Saimaa and Inari, the settlement of Neiden and up to the Barents Sea.

King Sigismund stated, that the minimal demands set by the Swedes would be a return to pre-war borders, and gain some compensation over territories.

The peace treaty was commercially beneficial to Sweden, due to designating Vyborg and Narva as international hubs for trade.

Tens of thousands of civilians were killed, which at that time was a much larger portion of the total population in the regions the war was waged on.
