 In the Middle Ages, the area belonged to Principality of Tver, and in the 14th century was, together with the principality, annexed by the Grand Duchy of Moscow.The trade route between Moscow and Veliky Novgorod crossed the area, and, in particular, Mednoye developed as a rich merchant locality on this route.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).
