Zubtsov was first mentioned in 1216. Due to its location on the Volga, it controlled one of the versions of the
Trade route from the Varangians to the Greeks. In the 14th century, the area belonged to
Principality of Tver. Between 1318 and 1460, separate
Zubtsov Principality existed with the seat in Zubtsov. It was subordinate to Principality of Tver. In 1460, it was abolished and merged back to Principality of Tver. In 1485, the area was included to the
Grand Duchy of Moscow. In the course of the
administrative reform carried out in 1708 by
Peter the Great, the area was included into
Ingermanlandia Governorate (since 1710 known as Saint Petersburg Governorate), and in 1727
Novgorod Governorate split off. In 1775,
Tver Viceroyalty was formed from the lands which previously belonged to
Moscow and Novgorod Governorates, and the area was transferred to Tver Viceroyalty, which in 1796 was transformed to
Tver Governorate. In 1775,
Zubtsovsky Uyezd was established, with the center in Zubtsov. The whole area of the district belonged to Zubtsovsky Uyezd. On 30 May 1922, Zubtsovsky Uyezd was abolished and merged into
Rzhevsky Uyezd. On 12 July 1929, governorates and uyezds were abolished, and Zubtsovsky District with the administrative center in the town of Zubtsov was established. It belonged to
Rzhev Okrug of
Western Oblast. On August 1, 1930 the okrugs were abolished, and the districts were subordinated directly to the oblast. On 29 January 1935
Kalinin Oblast was established, and Zubtsovsky District was transferred to Kalinin Oblast. During World War II, in 1941—1943, the district was occupied by German troops. In February 1963, during the abortive administrative reform by
Nikita Khrushchev, Zubtsovsky District was merged into Rzhevsky District, but on 12 January 1965 it was re-established. In 1990, Kalinin Oblast was renamed Tver Oblast. On 12 July 1929
Pogorelsky District, with the center in the
selo of
Pogoreloye Gorodishche was created as well. It was a part of Rzhev Okrug of Moscow Oblast. In 1934, the district was abolished. On 10 February 1935 Pogorelsky District was re-established and transferred to Kalinin Oblast. On 14 November 1960 Pogorelsky District was abolished and merged into Zubtsovsky District. ==Economy==
