History
The territory of the modern district was originally settled by Karelians around the 1st century CE. It was a part of the Kievan Rus' from the 9th to 12th century. After that, it was a part the Novgorod Republic. Most Karelians were converted to the Russian Orthodox faith during Russian rule. Russians built the fortress of Korela, which was a nucleus of modern Priozersk. The territory passed hands many times during the 16th and 17th centuries between Russians and Swedish, until it was finally claimed by Russians in 1711 during the Great Northern War. During Swedish rule in the area, the town was known by its Swedish name Kexholm, which in Russian became Keksgolm. In the 18th century, it was a part of Saint Petersburg Governorate, and later of Vyborg Governorate, which in 1812 was included in the newly created Grand Duchy of Finland as its Viipuri Province. It became part of independent Finland, when the former Grand Duchy declared its independence in December 1917. During the Interwar Period, the location was known by its Finnish and Swedish names; Käkisalmi and Kexholm. The area was ceded from Finland to the Soviet Union as a result of the 1939-40 Winter War. It was retaken by Finland during the 1941-44 Continuation War, regained by Soviet troops in 1944, and formally ceded to the Soviet Union in 1947. Nearly all of Finnish residents evacuated the area, which was repopulated by Russians, Ukrainians, and Belarusians. Place names were changed in 1948 to remove remaining Finnish names in the district. Keksgolmsky District with the administrative center in Keksgolm was established in March 1940 as a part of the Karelian Autonomous Soviet Socialist Republic. On March 31, 1940, the Karelian ASSR was transformed into the Karelo-Finnish Soviet Socialist Republic. On November 24, 1944, Keksgolmsky District was transferred from Karelo-Finnish Soviet Socialist Republic to Leningrad Oblast. On October 1, 1948, the district was renamed Priozersky, and Keksgolm was renamed Priozersk. On February 1, 1963 the district was abolished and merged into Vyborgsky District; on January 12, 1965 it was re-established. On May 16, 1940, Rautovsky District with the administrative center in the suburban settlement of Rautu was also established. It was a part of Leningrad Oblast. On October 1, 1948, the district was renamed Sosnovsky and on January 13, 1949, all localities whose names originated in Finnish were renamed using Russian names. In particular, Rautu was renamed Sosnovo. On December 9, 1960, Sosnovsky District was abolished and split between Roshchinsky and Priozersky Districts.
