History

Delmenhorst – Wesermarsch – Oldenburg-Land was created in 1949. In the 1949 election, it was Lower Saxony constituency 7. For the 1953 through 1961 elections, it was constituency 29 in the numbering system. From 1965 through 1998, it was constituency 23; from 2002 through 2009, it was constituency 29. Since the 2013 election, it has been constituency 28.

Originally, it comprised the city of Oldenburg, the district of Wesermarsch, and the municipalities of Dötlingen, Ganderkesee, Hasbergen, Hude, Schönemoor, Stuhr and Wildeshausen from Landkreis Oldenburg. At this time, it was named Delmenhorst – Wesermarsch. Due to administrative reforms, in the 1976 election, it gained the former municipality of Wüsting. In the 1980 election, the constituency gained the entirety of Landkreis Oldenburg. In the 1987 election, it was renamed to Delmenhorst – Wesermarsch – Oldenburg-Land.
