Foreign trade of medieval Novgorod
The city of Novgorod was a major trade hub from the beginning of its history as part of Kievan Rus' through the years of the Novgorod Republic in the 12th–15th centuries. Novgorod benefitted from its location at the crossroads of several major trading routes, including the route from Scandinavia to the Byzantine Empire and the Volga route connecting Rus' to the Middle East.
