Treaty of Polyanovka

The negotiations began on 30 April after the failure of the Polish-Lithuanian siege of Belaya.

Overall, the agreement confirmed the pre-war status quo, with Russia paying a large war indemnity (20,000 rubles in gold) for Władysław IV agreeing to surrender his claim to the Russian throne and return the royal insignia to Russia.

Władysław, despite holding an upper hand, was trying to bring Russia into an anti-Sweden alliance; hence in a gesture of goodwill he agreed to give the Russians the border town of Serpeysk and nearby territories.

The sides also reached an agreement on prisoner exchange and a trade treaty.

[1] The treaty ended the almost unbroken series of wars between the Commonwealth and its neighbours that had been waged since the beginning of the 17th century.
