Economy of the Pskov Republic
The economy of the Pskov Republic (1348–1510) was dominated by merchants trading to and from the city of Pskov (originally Pleskov) and the associated Pskov Land, primarily via the river Velikaya and connected waterways. It also had well-developed farming, fishing, blacksmithing, jewellery-making and construction industries.
