After the Russian conquest and the foundation of Saint Petersburg (1703), the flow of migration was reversed. Russian nobles were granted land in Ingria, and Lutheran Ingrian Finns left Ingria, where they were in minority, for the area known as Old Finland, north of the Gulf of Finland, which Russia had gained from Sweden during the 18th century, and where Lutherans were a large majority. There the Ingrian Finns assimilated with the Karelian Finns.
