existed: around 1740 a synagogue was built, replaced by a new construction in 1806. Until 1854, the parish grew to 154 people and represented nearly 9% of the village population. However, migration and emigration in the following time decreased the parish enormously. In 1880, merely 71 Jewish inhabitants, and in 1925 only 7 Jews were left. The Jewish parish broke up before 1933 and sold its synagogue to the Protestant parish. Five of Kochendorfs last seven Jews were killed by Nazi persecution between 1940-43. 1933-45 In 1933, Kochendorf combined with the neighbouring Jagstfeld into Bad Friedrichshall. Two years later, Hagenbach was incorporated. In September 1944, the SS established a subcamp of the Natzweiler-Struthof KZ in Kochendorf. in this last phase of the third reich concentration camps were erected near factories, quarries or mines using inmates as slave labor under the motto "Vernichtung durch Arbeit" (Destruction through work) Companies had to apply for a building modification at the Organisation Todt. Various military contractors and construction companies were involved: The Hochtief AG, a leading construction company which played a major role in the Third Reich, was commissioned to rebuild the halls into capable production facilities. A large scale expansion up to 40 or 50 mine chambers was planned. Another construction company was the company Koch & Mayer GmbH from Heilbronn. The aircraft company Ernst Heinkel AG had a leading position among the military companies in Kochendorf, commissioned to build experimental units for turbine He S 011, which was to be installed in the Messerschmitt Me P 1101 hunting aircraft. For this turbine, Robert Bosch GmbH and Siemens-Schuckert-Werke AG produced spark plugs, injection pumps and electrical materials. The Motorenwerke Mannheim AG had submarine engine components built in the mine. Only the production of machine guns could not be attributed to any company yet. A detailed permanent exhibition since 2012 can be visited in the Bad Friedrichshall Kochendorf saltmine. 1945-present On June 17, 1951, Bad Friedrichshall was raised to the level of a town. On March 15, 1972, Duttenberg and on January 1, 1975 Untergriesheim followed. From 1992 until 1998 in the context of increased migration and lack of dwellings for new immigrants the district Plattenwald was rebuilt as part of a flat building program of the state Baden-Württemberg.
