Geography

Steinburg – Dithmarschen Süd is located in central western Schleswig-Holstein. As of the 2021 federal election, it comprises the district of Steinburg, the southern part of the Dithmarschen district (specifically the urban municipality of Brunsbüttel, and the Ämter of Burg-Sankt Michaelisdonn, Marne-Nordsee, and Mitteldithmarschen), and the urban district of Bad Bramstedt and Amt of Bad Bramstedt-Land from the Segeberg district.^[1]

History

Steinburg – Dithmarschen Süd was created in 1965, then known as Steinburg – Süderdithmarschen. It contained parts of the abolished constituencies of Steinburg and Norder- und Süderdithmarschen. Until 1972, it was constituency 4 in the numbering system. From 1972 until 2002, its name contained a hyphen between "Dithmarschen" and "Süd".

In the elections of 1965 and 1969, Steinburg – Süderdithmarschen consisted of the districts of Steinburg and Süderdithmarschen. After reform of the administrative divisions in Schleswig-Holstein, the constituency acquired its current name and configuration, containing Steinburg and the southern part of Dithmarschen. In 2002, Bad Bramstedt and Bad Bramstedt-Land became part of Steinburg – Dithmarschen Süd.
