Ingrian Finns in the context of "Border Security Zone of Russia"

Finns or Finnish people (Finnish: suomalaiset, IPA: [ˈsuo̯mɑlɑi̯set]) are a Baltic Finnic ethnic group native to Finland. Finns are traditionally divided into smaller regional groups that span several countries adjacent to Finland, both those who are native to these countries as well as those who have resettled. Some of these may be classified as separate ethnic groups, rather than subgroups of Finns. These include the Kvens and Forest Finns in Norway, the Tornedalians in Sweden, and the Ingrian Finns in Russia.

Finnish, the language spoken by Finns, is closely related to other Balto-Finnic languages such as Estonian and Karelian. The Finnic languages are a subgroup of the larger Uralic family of languages, which also includes Hungarian. These languages are markedly different from most other languages spoken in Europe, which belong to the Indo-European family of languages. Native Finns can also be divided according to dialect into subgroups sometimes called heimo (lit. 'tribe'), although such divisions have become less important due to internal migration.

The Baltic Finnic peoples, often simply referred to as the Finnic peoples, are the peoples inhabiting the Baltic Sea region in Northern and Eastern Europe who speak Finnic languages. They include the Finns, Estonians (including Võros and Setos), Karelians (including Ludes and Livvi), Veps, Izhorians, Votes, and Livonians. In some cases the Kvens, Ingrians, Tornedalians and speakers of Meänkieli are considered separate from the Finns.

The bulk of the Finnic peoples (more than 98%) are ethnic Finns and Estonians, who reside in the two independent Finnic nation states—Finland and Estonia.

The Izhorians (Ingrian: ižorat, ižorit, inkeroiset; Russian: ижо́ра; ижо́ры, ижо́рцы; Finnish: inkerikot; Estonian: isurid) are a Finnic indigenous people native to Ingria. Small numbers can still be found in the western part of Ingria, between the Narva and Neva rivers in northwestern Russia. They are also referred to as Ingrians, although the term can also refer to the Ingrian Finns or the Baltic Finnic residents of Ingria in general.

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.

Ingrian (inkeroin keeli, Soikkola: [ˈiŋɡ̊e̞roi̯ŋ ˈke̝ːlʲi]), also called Izhorian (ižoran keeli, Soikkola: [ˈiʒ̥o̞rɑŋ ˈke̝ːlʲi], Ala-Laukaa: [ˈiʒo̞rəŋ ˈkeːlʲ]), is a Finnic language spoken by the (mainly Orthodox) Izhorians of Ingria. It has approximately 70 native speakers left, most of whom are elderly.

The Ingrian language should be distinguished from the Ingrian dialect of the Finnish language, which became the majority language of Ingria in the 17th century with the influx of Lutheran Finnish immigrants; their descendants, the Ingrian Finns, are often referred to as Ingrians. The immigration of Lutheran Finns was promoted by Swedish authorities, who gained the area in 1617 from Russia, as the local population was (and remained) Orthodox.

Swedish Ingria (Swedish: Svenska Ingermanland, ‘land of Ingrians’) was a dominion of the Swedish Empire from 1583 to 1595 and then again from 1617 to 1721 in what is now the territory of Russia. At the latter date, it was ceded to the Russian Empire in the Treaty of Nystad, at the end of the Great Northern War between the two empires.
