The Novgorod Republic was a medieval state that existed from the 12th to 15th centuries in northern Russia, stretching from the Gulf of Finland in the west to the northern Ural Mountains in the east. Its capital was the city of Novgorod. The republic prospered as the easternmost trading post of the Hanseatic League, and its people were much influenced by the culture of the Byzantines, with the Novgorod school of icon painting producing many fine works.
