Swedish Ingria (Swedish: Svenska Ingermanland, land of Ingaevones) was a dominion of the Swedish Empire from 1583 to 1595 and then again from 1617 to 1721, when it was ceded to the Russian Empire in the Treaty of Nystad.
Ingria was ceded to Sweden by Russia together with the County of Kexholm by the Treaty of Stolbovo in 1617. It consisted of the area along the basin of the river Neva, between the Gulf of Finland, the Narva River, Lake Peipsi in South-West, and Lake Ladoga in North-East. Bordering to Kexholm and Swedish Karelia by the Sestra (Rajajoki /Systerbäck) river in North-West.
Ingria fell to Sweden in the 1580s, was returned to Russia by the Treaty of Teusina (1595), and again ceded to Sweden in the Treaty of Stolbovo (1617). Sweden's interest of the territory was strategic: as a buffer zone against Russian attacks on the Karelian Isthmus and present-day Finland; and Russian trade was to pass through Swedish territory. In addition, Ingria became the destination for Swedish deportees.
Historical Ingria (Finnish: Inkeri or Inkerinmaa; Russian: Ингрия, Ingriya, Ижорская земля, Izhorskaya zemlya, or Ингерманландия, Ingermanlandiya; Swedish: Ingermanland; Estonian: Ingeri or Ingerimaa) is the geographical area located along the southern shore of the Gulf of Finland, bordered by Lake Ladoga on the Karelian Isthmus in the north and by the River Narva on the border with Estonia in the west.
The Orthodox Izhorians, along with the Votes, are the indigenous people of historical Ingria. With the consolidation of the Kievan Rus and the expansion of the Republic of Novgorod north, the indigenous Ingrians became Greek Orthodox. Ingria became a province of Sweden in the Treaty of Stolbovo in 1617 that ended the Ingrian War, fought between Sweden and Russia. After the Swedish conquest of the area in 1617 the Ingrian Finns, descendants of 17th-century Lutheran emigrants from present-day Finland, became the majority in Ingria. In 1710, following a Russian conquest, Ingria was designated as the Province of St. Petersburg. In the Treaty of Nystad (1721), Sweden formally ceded Ingria to Russia. In 1927 the Soviet authorities designated the area as Leningrad Province. Deportations of the Ingrian Finns started in late 1920s, and Russification was nearly complete by the 1940s. As of 2015, Ingria forms the northwestern anchor of Russia—its "window" on the Baltic Sea—with Saint Petersburg as its centre.
