The Eternal Peace of Polianovka ended the Smolensk War between Russia and Poland-Lithuania. The treaty saw Wladyslaw IV of Poland-Lithuania renounce his claim to the Russian throne, recognising Michael Romanov as Tsar. In return Russian officially acknowledged the Polish gains won in the earlier Polish-Muscovite War of 1609-1619 that had seen Poland-Lithuania gain the areas around Smolensk, Seversk and Chernihiv, moving the border between Poland-Lithuania and Russia up to one hundred miles to the east. Some of the territory lost in 1619 would not be regained by Russia until the 1660s.
