Karelo-Finnish Soviet Socialist Republic
The village of Kaarlahti was known since at least the 16th century and belonged interchangeably to Russia and Sweden. Since the middle of the 18th century, it was a part of Vyborg Governorate, which, in turn, since 1812 was a part of the Grand Duchy of Finland as the Viipuri Province. In 1916, the railway station was opened. In 1918, together with the rest of the Viipuri Province, Kaarlahti became a part of independent Finland. After the Winter War, it was reclaimed by the Soviet Union. Kaarlahti became a part of Keksgolmsky District with the administrative center in Keksgolm which was a part of the Karelian Autonomous Soviet Socialist Republic (Karelian ASSR). On March 31, 1940, the Karelian ASSR was transformed into the Karelo-Finnish Soviet Socialist Republic. During the Second World War, Kaarlahti was reclaimed by Finland and then again ceded to the Soviet Union. On November 24, 1944, Keksgolmsky District was transferred from Karelo-Finnish Soviet Socialist Republic to Leningrad Oblast.
