History
The fortress of Bely is first mentioned in a chronicle in 1350, since it was conquered by the Grand Duchy of Lithuania. It was located on the border between Lithuanian and Russian lands, and intermittently changed affiliation between Lithuania and the Grand Duchy of Moscow, until in 1654 it finally went to 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 Belsky District with the administrative center in the town of Bely 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 27 September 1937 Western Oblast was abolished and split between Smolensk and Oryol Oblasts. Belsky District was transferred to Smolensk Oblast. During World War II, in 1941—1943, the district was occupied by German troops. On August 22, 1944, the district was transferred to newly established Velikiye Luki Oblast. On October 2, 1957, Velikiye Luki Oblast was abolished, and Belsky District was transferred to Kalinin Oblast. On February 13, 1963 the district was abolished and merged into Nelidovsky District; on November 3, 1965 it was re-established. In 1990, Kalinin Oblast was renamed Tver Oblast.
