Towns and municipalities in Dithmarschen developed from the old parishes that were independent political divisions in the medieval farmers' republic. These parishes existed as primary political divisions until the 19th century. Only Meldorf was able to develop an urban structure during the Middle Ages.
In more recent times Heide became a rival to Meldorf. Wesselburen and Wöhrden had some importance as central villages of the rich northern marshland.
After Schleswig-Holstein was annexed by Prussia in 1867, some villages became towns and therefore administratively left their old parishes: Meldorf in 1869, Heide in 1878, Marne in 1891, and Wesselburen in 1899. The old village of Brunsbüttel and the newly founded Brunsbüttelkoog united in 1970 to become the town of Brunsbüttel.
Parishes were finally dissolved and single villages became independent during the Nazi period. For efficient administration, municipalities are united in Ämtern, which for historical reasons are named Amt Kirchspielslandgemeinden (Amt Parish's Country Municipalities).
The largest town by population is Heide. Büsum has a special role as tourist resort. Although a member of an Amt, its summertime population swells to become the largest in the district.
In socio-geographics the difference between marshland and the higher, dryer uplands has played an important role. The fertile marshland was historically rich while the uplands were poor but less prone to flooding. The two most important towns, Heide and Meldorf, were built on the safe geest but directly adjacent to marshland where people could have their fields.
