The Republic of North Ingria (Finnish: Pohjois-Inkerin tasavalta), or Republic of Kirjasalo (Finnish: Kirjasalon tasavalta), was a short-lived, small state for the Ingrian Finns in the southern part of the Karelian Isthmus, which seceded from Bolshevist Russia after the October Revolution. Its aim by most proponents was to ultimately be incorporated into the Kingdom of Finland, and it ruled parts of Northern Ingria from 1919 until 1920. With the Peace Treaty of Tartu, it was re-integrated into Russia; however, Ingrian Finns of this area enjoyed a certain degree of national autonomy until the 1930s in compliance with the policy of national delimitation in the Soviet Union.
