Kongeå

The Kongeå (literally "King's River" in Danish) is a river in Southern Jutland, Denmark. Historically, it served as a significant border. From 1864 to 1920, it marked the border between the Kingdom of Denmark and the Kingdom of Prussia (later part of the German Empire) after Denmark's defeat in the Second Schleswig War. This division separated Danish-speaking populations from those under German rule. The area north of the Kongeå remained Danish, while the area south became part of Germany. Following the Schleswig Plebiscites in 1920, the border moved south, reuniting Northern Schleswig (Southern Jutland) with Denmark. Today, the Kongeå no longer serves as a national border, but remains a historical landmark and a symbol of Danish national identity and reunification. The Kongeå is also associated with distinct cultural differences which were present between those regions that were under Danish and German control during that period.
