Population: History Originally called Enso, the town was founded in 1887 to serve a paper mill. At the time, Enso was part of Viipuri Province and the Jääski Municipality in the Grand Duchy of Finland, which was an autonomic state within the Russian Empire. When Finland became independent in 1917, Enso remained part of Finland. The territory was ceded by Finland to the Soviet Union by the Moscow Peace Treaty as a result of the Winter War. After the Winter War, the Finns and the Soviets disagreed on the interpretation of the peace treaty regarding Enso. The former Minister for Foreign Affairs of Finland Väinö Tanner wrote in his memoirs: "Already now a dispute about the district of Enso developed. According to the map attached to the peace treaty Enso was clearly intended to belong to Finland but the Russians claimed that it should belong to them. Later the map was redrawn according to the interests of the Russians so that the border bends at Enso." In March 1940, Enso became a part of Yaskinsky District with the administrative center in the work settlement of Yaski. It was a part of the Karelian Autonomous Soviet Socialist Republic, after March 31, 1940 of the Karelo-Finnish Soviet Socialist Republic. Enso was recaptured by Finns between 1941 and 1944 during the Continuation War but was again ceded to Soviets by the Moscow Armistice. This secession was formalized after signing the Paris Peace Treaty in 1947. The Finnish population was resettled to Finland, while migrants from Central Russia resettled the Karelian Isthmus. On November 24, 1944, Yaskinsky District was transferred from Karelo-Finnish SSR to Leningrad Oblast. On October 1, 1948, the district was renamed Lesogorsky and on January 13, 1949, all Finnish names of the localities were replaced with Russian names. In particular, Enso was renamed Svetogorsk. On December 9, 1960, Lesogorsky District was abolished and merged into Vyborgsky District. In 1972, the Soviet Union awarded Finland a construction project for a large new cellulose and paper mill in Svetogorsk. The project was paid with Soviet crude oil. The project also gave a start to cross-border relations. Notably, the construction workers in Svetogorsk were called
