 In the Middle Ages, the area was divided between Principality of Tver and the Novgorod Republic.Principality of Tver and the Bezhetsk Verkh, a part of the Novgorod Republic, were annexed by Moscow in the 14th century, and in the 15th century Novgorod followed, after which the north of the current area of the district was included into Bezhetsk Pyatina, one of the five pyatinas into which the Novgorod Lands were divided.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), but in 1727 it was transferred to Moscow Governorate.
