Novgorod Republic
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.
