The Novgorod Republic, formally known as Lord Novgorod the Great, was a city-state that existed from the 12th to 15th centuries in northwestern Russia, stretching from the Gulf of Finland in the west to the 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. For much of its history, Novgorod was the center of Russian art and culture.
Novgorod formally won its independence in 1136 after the Novgorodians deposed their prince and the Novgorod veche began to elect and dismiss princes at its own will. By the 13th century, the prince's power had greatly diminished.
