Dettenheim dates back to 788 and was located right on the banks of the Rhein River. Due to persistant flooding, all of the villagers moved in 1813 to a new location approximately sixteen kilometers south southeast and founded the town of Karlsdorf. Today, only a few buildings remain in the area that was previously Dettenheim (now called Alt-Dettenheim). The area of Alt-Dettenheim was merged in 1975 with the former municipalities of Liedolsheim and Rußheim into a new city called Dettenheim.

Hochstetten merged in 1975 with the neighboring village of Linkenheim to form Linkenheim-Hochstetten. This municipality is part of the Karlsruhe metropolitan area.
