Middle Ages
Ingersheim was first mentioned in a document of the Lorsch Monastery (Lorsch Codex) in 779. Whether it was Großingersheim or Kleiningersheim can no longer be determined. Most likely Großingersheim. In the area of Großingersheim, archaeological findings indicate an early medieval settlement from the Frankish-Merovingian period. In the early Middle Ages Ingersheim was a main settlement of the Counts of Calw with its own court.
At the beginning of the 15th century, Ingersheim became part of Baden, followed by Electoral Palatinate rule. In 1504 Ulrich von Württemberg took possession of the two present-day sub-villages, which have been part of Württemberg since then.
Modern times
After the foundation of the Kingdom of Württemberg, Ingersheim belonged to the Oberamt Bietigheim until 1810, and then to the Oberamt Besigheim. In 1938, in the course of a Württemberg territorial reform during the Nazi era, the suburbs of Groß- and Kleiningersheim, which had been formed in 1829, became part of the district of Ludwigsburg.
During World War II, Großingersheim was substantially destroyed in a bombing raid on December 16, 1944, and was initially occupied by French troops on April 21, 1945. After the war, however, the town became part of the American occupation zone and thus belonged to the newly founded state of Württemberg-Baden, which was absorbed into the current state of Baden-Württemberg in 1952.
Today's Ingersheim was formed on January 1, 1972, out of the two previously independent municipalities of Großingersheim and Kleiningersheim. The separation of the two "Ingersheims", which had only taken place in 1829, was thus reversed.
