with the Church of the Holy Cross in
Lisino-Korpus in the background. Originally, the area of the district was populated by
Finnic peoples. From the 9th century, the area was changing hands between
Novgorod Republic (from the 15th century, the
Grand Duchy of Moscow), and
Sweden. In 1617, according to the
Treaty of Stolbovo, the area was transferred to Sweden, and in the 1700s, during the
Great Northern War, it was conquered back by Russia. The city of Saint Petersburg was founded in 1703. In the course of the
administrative reform carried out in 1708 by
Peter the Great, the area was included into Ingermanland Governorate (known since 1710 as
Saint Petersburg Governorate). In 1727,
Novgorod Governorate split off. The eastern part of the area was a part of
Novgorodsky Uyezd of Novgorod Governorate. The western part remained in Saint Petersburg Governorate and later was split between
Tsarskoselsky and
Sankt-Peterburgsky Uyezds (renamed in 1913 Petrogradsky Uyezd and in 1924 Leningradsky Uyezd; the governorate was accordingly renamed Petrogradsky in 1913 and Leningradsky in 1924). On November 20, 1918
Tsarskoye Selo was renamed Detskoye Selo, and the uyezd was renamed Detskoselsky. On February 14, 1923 Detskoselsky and
Petergofsky Uyezds were abolished and merged into
Gatchinsky Uyezd, with the administrative center located in
Gatchina. On August 1, 1927, the uyezds were abolished and
Lyubansky District, with the administrative center in the town of
Lyuban, was established. The governorates were also abolished, and the district was a part of
Leningrad Okrug of
Leningrad Oblast. It included parts of former Novgorodsky Uyezds. On July 23, 1930, the okrugs were abolished as well, and the districts were directly subordinated to the oblast. On August 19, 1930 Lyubansky District was abolished, and Tosnensky District with the administrative district in Tosno was established on the areas occupied by Lubansky District and parts of
Detskoselsky and
Kolpinsky Districts. On August 20, 1935 Tosno and
Krasny Bor were granted urban-type settlement status. Between September 1941 and January 1944, during
World War II, the district was occupied by
German troops. On December 9, 1960 parts of abolished
Mginsky District were transferred to Tosnensky District, and in 1977, they were split off to form Kirovsky District. On February 1, 1963 Tosno was granted town status. On August 1, 1927
Detskoselsky District was established as well, with the administrative center in the town of
Detskoye Selo. It was a part of Leningrad Okrug of Leningrad Oblast and included areas formerly belonging to Gatchinsky and Novgorodsky Uyezds. The town of
Slutsk was also a part of the district. On August 19, 1930 the district was abolished and split between Tosnensky,
Krasnogvardeysky, and
Leningradsky Prigorodny Districts. Another district established on August 1, 1927 was
Kolpinsky District, with the administrative center in the town of
Kolpino. It was a part of Leningrad Okrug of Leningrad Oblast and included areas formerly belonging to Leningradsky and Gatchinsky Uyezds. On August 19, 1930 the district was abolished and split between Tosnensky and Leningradsky Prigorodny Districts. On August 19, 1936
Slutsky District was established. It included some aread from abolished
Leningradsky Prigorodny District and from Tosnensky District. On June 23, 1939 parts of Krasnogvardeysky District were transferred to Slutsky District. Between September 1941 and January 1944 parts of the district were occupied by German troops. On April 23, 1944 Slutsk was renamed Pavlovsk, and the district was renamed Pavlovsky. On July 25, 1953 Pavlovsky District was abolished and split between the city of Leningrad, Gatchinsky, and Tosnensky Districts. ==Economy==
