History
Vydropuzhsk, one of the oldest settlement in the district, was first mentioned in 1545.[10] 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. On April 2, 1772 Vyshnevolotsky Uyezd of Novgorod Governorate was established, with the seat in Vyshny Volochyok. 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. The area was split between Vyshnevolotsky and Novotorzhsky Uyezds. In particular, Vydropuzhsk belonged to Novotorzhsky Uyezd,[11] whereas Spirovo, which was founded in 1847, belonged to Vyshnevolotsky Uyezd.[12]
On July 12, 1929 the governorates and uyezds were abolished. Spirovsky District, with the administrative center in Spirovo, was established within Tver Okrug of Moscow Oblast. On July 23, 1930, the okrugs were abolished, and the districts were directly subordinated to the oblast. On January 29, 1935 Kalinin Oblast was established, and Spirovsky District was transferred to Kalinin Oblast.[13] In February 1963, during the abortive administrative reform by Nikita Khrushchev, Spirovsky District was merged into Vyshnevolotsky District, but on January 12, 1965 it was re-established. During this period, Spirovo was administratively a part of the town of Vyshny Volochyok.[10] In 1990, Kalinin Oblast was renamed Tver Oblast.
Another district created on July 12, 1929 was Tolmachyovsky District with the administrative center in the selo of Tolmachi. It was a part of Tver Okrug of Moscow Oblast. On January 29, 1935 the district was transferred to Tver Oblast, and on March 5, 1935 it was renamed Novokarelsky District. On July 9, 1937 it was transferred to Karelian National Okrug, a Tver Karelians autonomy. On February 7, 1939 the okrug was abolished, and the district was subordinated directly to Kalinin Oblast. On July 4, 1956 it was abolished and split between Spirovsky and Likhoslavlsky Districts.[13]
On July 9, 1937 Kozlovsky District with the administrative center in the selo of Kozlovo was established as a part of Karelian National Okrug. On February 7, 1939 it was subordinated directly to Kalinin Oblast. On July 4, 1956 it was abolished and split between Maksatikhinsky and Spirovsky Districts.[13]
