Editing Flensburg (section)

===Since the Second World War===
After the Second World War, the town's population broke the 100,000 mark for a short time, making Flensburg a city (''Großstadt'') under one traditional definition. The population later sank below that mark.

In the years after the Second World War, South Schleswig, and particularly Flensburg, had a strong pro-Danish movement connected with the idea of the "Eider Politics". Its goal was for the town and all or most of Schleswig, the whole area north of the [[Eider River]], to be united with Denmark. After 1945, Flensburg's town council was for years dominated by Danish parties, and the town had a Danish mayor.

The town profited from the planned location of military installations. Since [[German Reunification]], the number of soldiers has dropped to about 8,000. Since Denmark's entry into the [[European Economic Community]] (now the [[European Union]]), border trade has played an important role in Flensburg's economic life. Some Danish businesses, such as [[Danfoss]], have set up shop just south of the border for tax reasons.

In 1970, the Flensburg district was expanded to include the municipalities in the Amt of Medelby, formerly in the Südtondern district, and in 1974 it was united with the Schleswig district to form the district of Schleswig-Flensburg, whose district seat was the town of [[Schleswig (city)|Schleswig]]. Flensburg thereby lost its function as a district seat but remained an independent (district-free) town.
