Ingria (Ингрия, Ингерманландия, Ижорская земля, Inkeri, Inkerinmaa, Ingermanland, Ingeri, Ingerimaa) 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 indigenous European peoples of the region are the now mostly Eastern Orthodox Izhorians and Votians, as well as the Ingrian Finns who descend from the Lutheran Finnish immigrants who settled in the area in the 17th century, when Finland proper and Ingria were both parts 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 Ingrians, understood as the inhabitants of Ingria regardless of ethnicity, can hardly be said to have been a nation, although the Soviet Union recognized their "nationality"; as an ethnic group, the Ingrians proper, Izhorians, are close to extinction together with their language. This notwithstanding, many people still recognize 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.
The names of the region are: Ingermaa, Inkeri or Inkerinmaa; Ингрия, Ingriya, Ижора, Izhora, or Ингерманландия, Ingermanlandiya; Ingermanland; Ingeri or Ingerimaa.
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 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".
