History
The area belonged to Principality of Smolensk since the 12th century. Later, Principality of Toropets split off, and the area was a part of it. In the 14th century, it was included into the Grand Duchy of Lithuania. In the 16th century, it went 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 Belsky Uyezd of Smolensk Governorate and remained there until 1929, with the exception of the brief periods between 1713 and 1726, when it belonged to Riga Governorate, and between 1775 and 1796, when Smolensk Governorate was transformed into Smolensk Viceroyalty. On 12 July 1929, governorates and uyezds were abolished, and Nelidovsky District with the administrative center in the settlement of Nelidovo 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 1935Kalinin Oblast was established, and Nelidovsky District was transferred to Kalinin Oblast. During World War II, in 1941—1943, the district was occupied by German troops. On 22 August 1944, the district was transferred to newly established Velikiye Luki Oblast. On October 2, 1957, Velikiye Luki Oblast was abolished, and Nelidovsky District was transferred back to Kalinin Oblast. On February 1, 1963, during the abortive Khrushchyov administrative reform, Oleninsky and Belsky Districts were merged into Nelidovsky District, and a part of Nelidovsky District was transferred to Zapadnodvinsky District. In 1964-65 Oleninsky and Belsky Districts were re-established. In 1990, Kalinin Oblast was renamed Tver Oblast.
