Ingria is a historical region in what is now northwestern European Russia. It lies along the southeastern 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 earliest known modern inhabitants of the region were indigenous Finnic ethnic groups, primarily the Izhorians and Votians, who converted to Eastern Orthodoxy over several centuries during the late Middle Ages. They were later joined by the Ingrian Finns, descendants of 17th century Lutheran Finnish immigrants to the area. At that time, modern Finland proper and Ingria were both part of the Swedish Empire.
Ingria as a whole never formed a separate state; however, North Ingria was an independent state for just under two years in 1919–1920. The inhabitants of Ingria cannot be said to have comprised a distinct nation, since the population is made up of several different ethnic groups, despite the Soviet Union recognizing Ingrian as a nationality. The indigenous peoples of Ingria, like the Votians and Izhorians, are today close to extinction, together with their languages. This notwithstanding, many people still recognize and attempt to preserve their Ingrian heritage.
Historic Ingria covers approximately the same area as the Gatchinsky, Kingiseppsky, Kirovsky, Lomonosovsky, Tosnensky, Volosovsky and Vsevolozhsky districts of modern Leningrad Oblast as well as the city of Saint Petersburg.
History

In the Viking era (late Iron Age), from the 750s onwards, Ladoga served as a bridgehead on the Varangian trade route to Eastern Europe. A mixed slavic-varangian aristocracy developed that would ultimately rule over Novgorod and Kievan Rus'. In the 860s, the warring Finnic and Slavic tribes rebelled under Vadim the Bold, but later asked the Varangians under Rurik to return and to put an end to the recurring conflicts between them.
The Swedes referred to the ancient Novgorodian land of Vod people as Ingermanland, Latinized to Ingria. The origin of the name is uncertain, but there are several possible explanations. One explanation is that the name comes from the River Inger, a southern tributary of the Neva River. Another explanation is based on the Norwegian Eymund's saga, which tells the story of the Swedish princess Ingegerd Olofsdotter, who married Yaroslav the Wise, Grand Prince of Novgorod and Kiev in 1019. According to the saga, she received Ladoga and the surrounding lands as a wedding gift from Yaroslav, and the region came to be known as Ingegerd's land, or Ingermanland. The lands were administered by Swedish jarls, such as Ragnvald Ulfsson, under the sovereignty of the Novgorod Republic.
In the 12th century, Western Ingria was absorbed by the Novgorod Republic. There followed centuries of frequent wars, chiefly between Novgorod and Sweden, and occasionally involving Denmark and Teutonic Knights as well. The Teutonic Knights established a stronghold in the town of Narva, followed by the Russian castle Ivangorod on the opposite side of the Narva River in 1492.
With the consolidation of the Kievan Rus and the expansion of the Republic of Novgorod north, the indigenous Ingrians became Eastern 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 in 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.
In the modern era, Ingria forms the northwestern anchor of Russia—its "window" on the Baltic Sea—with Saint Petersburg as its centre.
Swedish Ingria
Although Sweden and Novgorod had fought for the Ingrian lands more or less since the Great Schism of 1054, the first actual attempt to establish Swedish dominion in Ingria appears to date from the early 14th century, when Sweden first founded the settlement of Viborg in Karelia and then the fortress Landskrona (built in 1299 or 1300) at the confluence of the Ohta and Neva rivers. However, Novgorod re-conquered Landskrona in 1301 and destroyed it. Ingria eventually became a Swedish dominion in the 1580s, but the Treaty of Teusina (1595) returned it to Russia in 1595. Russia in its turn ceded Ingria to Sweden in the Treaty of Stolbova (1617) after the Ingrian War of 1610–1617. Sweden's interest in the territory was mainly strategic: the area served as a buffer zone against Russian attacks on the Karelian Isthmus and on present-day Finland, then the eastern half of the Swedish realm; and Russian Baltic trade had to pass through Swedish territory. The townships of Ivangorod, Jama (now Kingisepp), Caporie (now Koporye) and Nöteborg (now Shlisselburg) became the centres of the four Ingrian counties (slottslän), and consisted of citadels, in the vicinity of which were small boroughs called hakelverk – before the wars of the 1650s mainly inhabited by Russian townspeople. The degree to which Ingria became the destination for Swedish deportees has often been exaggerated.
Ingria remained sparsely populated. In 1664 the total population amounted to 15,000. Swedish attempts to introduce Lutheranism, which accelerated after an initial period of relative religious tolerance,
met with repugnance on the part of the majority of the Orthodox peasantry, who were obliged to attend Lutheran services; converts were promised grants and tax reductions, but Lutheran gains were mostly due to voluntary resettlements by Finns from Savonia and Finnish Karelia (mostly from Äyräpää).
The proportion of Lutheran Finns in Ingria (Ingrian Finns) comprised 41.1% in 1656, 53.2% in 1661, 55.2% in 1666, 56.9% in 1671 and 73.8% in 1695, the remainder being Russians, Ingermanland was to a considerable extent enfiefed to noble military and state officials, who brought their own Lutheran servants and workmen. However, a small number of Russian Orthodox churches remained in use until the very end of the Swedish dominion, and the forceful conversion of ethnic Russian Orthodox forbidden by law.
Nyen became the main trading centre of Ingria, especially after Ivangorod dwindled, and in 1642 it was made the administrative centre of the province. In 1656 a Russian attack badly damaged the town, and the administrative centre moved to Narva.
In 1945, after the Second World War, Estonian Ingria, then in the Soviet Union, was transferred to the Russian SFSR and incorporated into the Leningrad Oblast. Since Estonia reclaimed its independence in 1991, this territory has been disputed. As Russia does not recognize the Treaty of Tartu, the area currently remains under Russian control.
Soviet Ingria

After the 1917 Bolshevik revolution in Russia, the Republic of North Ingria () declared its independence from Russia with the support of Finland and with the aim of incorporation into Finland. It ruled parts of Ingria from 1919 until 1920. With the Russian-Finnish Peace Treaty of Tartu it was re-integrated into Russia, but enjoyed a certain degree of autonomy.
At its height in the 1920s, there were about 300 Finnish language schools and 10 Finnish language newspapers in Ingria.
The First All-Union Census of the Soviet Union in 1926 recorded 114,831 Leningrad Finns, as Ingrian Finns were called. On 25 March 1935, Genrikh Yagoda authorized a large-scale deportation targeting Estonian, Latvian and Finnish kulaks and lishentsy residing in the border regions near Leningrad. About 7,000 people (2,000 families) were deported from Ingria to Kazakhstan, Central Asia and the Ural region. In May and June 1936 the entire Finnish population of the parishes of Valkeasaari, Lempaala, Vuole and Miikkulainen near the Finnish border, 20,000 people, were resettled to the areas around Cherepovets and Siberia in the next wave of deportations. In Ingria they were replaced with people from other parts of the Soviet Union, mostly Russians but also Ukrainians and Tatars.
