Literally meaning "the Middle Land", it is situated in north-central Latvia north of the Daugava River.
In ancient times, the territory of Vidzeme was inhabited by Latgalians and Livs (near the coast of the Gulf of Riga and along the lower reaches of the Daugava and Gauja rivers).
After the Polish-Swedish War concluded by the Truce of Altmark in 1629, Sweden acquired the western part of the Duchy of Livonia roughly as far as the Aiviekste River, since then forming Vidzeme's eastern border.
During the course of the Great Northern War, Swedish Livonia was conquered by the Russian Empire and ceded to Russia at the Treaty of Nystad in 1721.
During World War II, the region was occupied by the Soviet Union from 1940, and then by Nazi Germany from 1941 to 1944.
