It is known that during the 16th and 17th centuries a settlement existed here known as Shuyezerskypogost (a Russian form of the local Karelian name, meaning "swampy lake"). The first documented mention dates from 1589 when Suoyarvi is recorded as church community controlled by the Orthodox community of Sortavala.[citation needed] In 1630, Suoyarvi became an independent community.
An outcome of theWinter War was that most ofWest Karelia was occupied by theSoviet Union in 1940, when Suoyarvi was granted town status.[citation needed] In August 1941, the territory was re-occupied byFinnish troops, but as part of the wider post-war settlement, it reverted to the Soviets in 1944; it was the second largest territory by area (afterPetsamo) ceded byFinland to theSoviet Union following theContinuation War. Before the occupation, Suoyarvi was geographically the easternmost municipality of Finland.[9]
Suoyarvi had its own dialects of the Karelian language before the area was ceded to the Soviet Union and its inhabitants were relocated to other parts of Finland. Most of the Karelian people in the former municipality spoke a variety of South Karelian (suvikarjala), while the villages in the Hyrsylä (Khyursyulya) salient, which also included Ignoila (Ignoyla) and Hautavaara (Khautavaara), spoke aLivvi dialect instead.[10]
