The North Sea Region (NSR) of Europe refers to European countries and regions that have access to the North Sea. Cultural and economic co-operation has a strong tradition in the area, dating back to the Vikings[1] and the Hanseatic League.[2]
Although not a formally established entity, in political terms the North Sea Region is consolidated through international organisations like the North Sea Commission and transnational co-operation programmes like the North Sea Region Programme of the European Union.
