In 795 the town was first mentioned in a document as Hemmingisbach in the
Lorsch Codex. It was about a border settlement to the property of the
Lorsch Abbey in the "Mark Heppenheim", including Hemsbach. After the dissolution of the abbey in 1232, the village was a bone of contention between the
Electoral Palatinate and the Archbishops of
Mainz for a century, until the Palatinate was adjudicated the villages of Hemsbach, Laudenbach and Sulzbach in 1344 by arbitration. The town was assigned to
Palatinate-Mosbach in 1410. Count
Otto of Mosbach pledged a large part of the rights to the
Prince-Bishopric of Worms in 1449. After the Palatinate-Mosbach line died out in 1499, however, customs privileges were returned to the Electoral Palatinate, which also claimed regional sovereignty. The dispute remained unresolved until Hemsbach finally fell to the Electorate Palatinate in 1705 under an exchange agreement with the Bishop of Worms. At the dissolution of the Electoral Palatinate Hemsbach was taken by
Baden in 1803 and annexed to the
Weinheim administration. On the night of May 1, 1811, a stagecoach with two Swiss merchants was attacked by Hölzerlips and his gang on the Bergstraße just short of Hemsbach. Hans Jacob Rieter from
Winterthur died of his injuries. In 1812, the Sulzbach settlement in the south of Hemsbach was separated and became independent. During the "
Baden Revolution" in 1849, Hessian troops and Baden rebels met near Hemsbach and engaged in heavy fighting. A cannon ball in the outer wall of the Hemsbach train station still commemorates this today. Politically, the
national liberals dominated since the foundation of the Reich in 1871 until they were ousted by the
Social Democrats in 1907, who were usually the strongest party also during the Weimar Republic. In the
1933 German federal election, the
Nazi Party received 30 percent and the
Communist Party 21 percent of the votes. The Cäsar-Oppenheimer-Platz is named after a Jewish 91-year-old man who died in 1940 as a result of his deportation to
Gurs internment camp. At least 15 of the 54 Jewish inhabitants living in Hemsbach in 1933 died in the persecutions of the Jews during the Nazi era until 1945. With the dissolution of the
district of Mannheim within the scope of the municipal reform of 1973, the municipality became part of the new
Rhein-Neckar-Kreis. In 1979 the municipality of Hemsbach was given the status of a town. In 1983, the Hemsbach district Rennhof changed the federal state: it was incorporated into Hüttenfeld, a district of
Lampertheim in Hesse. == Religions ==
