Ingrian (also called Izhorian) is a nearly extinct Finnic language spoken by the (mainly Orthodox) Izhorians of Ingria. It has approximately 120 speakers left, most of whom are aging. It should not be confused with the Southeastern dialects of the Finnish language that became the majority language of Ingria in the 17th century with the influx of Lutheran Finnish immigrants (whose descendants, 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.
In 1932–1937, a Latin-based orthography for the Ingrian language existed, taught in schools of the Soikino Peninsula and the area around the mouth of the Luga River. Several textbooks were published, including, in 1936, a grammar of the language. However, in 1937 the Izhorian written language was abolished and mass repressions of the peasantry began.
