Süßen was first mentioned with the name of Siezun in the Lorsch codex in 1071. Großsüßen was at first in the possession of the count of Helfenstein, who, in 1382 pledged it to the city ofUlm. Kleinsüßen, on the other hand, was in the hands of the family Pappenheim. They inherited the land forward to the landlords of Bubenhofen. In frames of the Mediatization in 1802, Großsüßen was given to Bavaria but in 1810 the lands were given back, in frames of an exchange contract to Württemberg. Kleinsüßen was on the other hand never Bavarian land. After the exchange, both places, Groß- and Kleinsüßen were assigned under the Head Office of Geislingen. With the opening of the Fils Valley Railway and Süßen station in 1847, Kleinsüßen was connected to the public transportation. In 1933, the two townships, Großsüßen and Kleinsüßen were unified and the settlement Süßen was formed. The war reform in 1938 assigned the town to the region of Göppingen. On July 1, 1996, Süßen obtained the title of town.
Religion
In 1539 Protestantism was officially introduced in Großsüßen, being part of Ulm. Kleinsüßen, owned by the Pappenheims, remained Roman Catholic.
The official coat of arms contains a black-white part and three red zig-zag lines. This shield became the official coat of arms in 1933. The red zig-zag lines represent the landlords of Bubenhofen, the former land owners. The black-white part represents the connections to Ulm. The red-white flag of the town was given on 13. March 1958 by the Ministry of Internal Affairs.
