Truce of Deulino (also known as Peace or Treaty of Dywilino), was signed in 11 December 1618 and put in effect on 4 January 1619. It concluded the Dymitriad wars (also known as the Polish-Muscovite War (1605-1618)) between the Polish-Lithuanian Commonwealth and Russian Tsardom. The agreement enlarged the Commonwealth to its greatest geographical extent in history, which lasted until the Commonwealth conceded the loss of Livonia in 1629. The Truce gave the Commonwealth control over some conquered territories, including the city of Smolensk (Smolensk Voivodeship) and Chernigov Voivodship and proclaimed a 14 and a half year truce. Władysław, son of Commonwealth king Sigismund III Vasa , refused to relinquish his claim to the Moscow throne, even though his father had already done so.
