The Novgorod Republic was a medieval state that existed from the 12th to 15th centuries, stretching from the Gulf of Finland in the west to the northern Ural Mountains in the east, including the city of Novgorod and the Lake Ladoga regions of modern Russia. The Republic prospered as the easternmost trading post of the Hanseatic League and its Slavic, Baltic and Finnic people were much influenced by the culture of the Viking-Varangians and Byzantine people.
