Swedish Livonia was a dominion of the Swedish Empire from 1629 until 1721. The territory, which constituted the southern part of modern Estonia and the northern part of modern Latvia, represented the conquest of the major part of the Polish-Lithuanian Duchy of Livonia during the 1600–1629 Polish-Swedish War. Parts of Livonia and the city of Riga were under Swedish control as early as 1621 and the situation was formalized in the Truce of Altmark 1629, but the whole territory was not ceded formally until the Treaty of Oliva in 1660. The minority part of the Wenden Voivodeship retained by the Polish–Lithuanian Commonwealth was renamed the Inflanty Voivodeship, which today corresponds to the Latgale region of Latvia.
