Municipality parts: In 1294, Elchingen (today: Unterelchingen) was sold by Konrad of Plochingen to the Cistercian monastery of Salem.

One day later the Battle of Ulm began, after which Karl Mack von Leiberich finally had to capitulate.

In 1806 Napoleon conferred the title of Duc d'Elchingen on Marshal Ney[3] and the name of Elchingen was engraved on the Arc de Triomphe in Paris.

For the region the Napoleonic victory meant the end of the Austrian supremacy which led to a re-organization of the area of Württemberg and Bavaria.

Today's municipality of Elchingen is the result of the reorganization of Bavaria on 1 May 1978 through the integration of Thalfingen, Oberelchingen and Unterelchingen.
