The
Novgorod Republic (; ) was a medieval
Russian state which stretched from the
Baltic Sea to the northern
Ural Mountains between the 12th and 15th centuries, which included the city of
Novgorod and the Lake Ladoga regions. Citizens referred to their city-state as "His Majesty (or Sovereign) Lord Novgorod the Great" (
Gosudar Gospodin Velikij Novgorod), or more often as "Lord Novgorod the Great" (
Gospodin Velikij Novgorod). The Republic prospered as the easternmost port of the
Hanseatic League.
