Territories marked in orange were gained by the Polish–Lithuanian Commonwealth. Much of these territories, including the city of Smolensk, used to belong to the Grand Duchy of Lithuania before its union with the Kingdom of Poland. They would later be re-conquered by the Tsardom of Russia in the second half of the 17th century as per the terms of the Treaty of Andrusovo.

The Truce of Deulino (also known as Peace or Treaty of Dywilino) concluded the Polish–Russian War of 1609–1618 between the Polish–Lithuanian Commonwealth and the Tsardom of Russia. It was signed in the village of Template:Ill on 11 December 1618 and took effect on 4 January 1619.<ref name=dict>Template:Cite book</ref>
