City Districts Forchheim In 1086 Forchheim was mentioned for the first time in an official document by Henry IV, Holy Roman Emperor; ‘Vorechheim’ was noted as a gift. Until 1100 Forchheim was the principle estate of "Ufgau", known as County Forchheim. The rule of this county was gradually taken from the Forchheim-Malch family and in 1086 came under the rule of the Roman Catholic Diocese of Speyer. Then Forchheim was given to Herman V (Margrave of Baden-Baden), then returned to the county and in 1219 passed back to Herman V (Margrave of Baden-Baden), who became the liege lord of Forchheim. Later, Forchheim came under the administration of Mühlburg and in the course of the division of lands it went to the Margraviate of Baden. At this time it belonged to the administration of Ettlingen. In 1921, it became part of the district office Karlsruhe, which in 1938 became the district Karlsruhe. Since 1963 the head office of Bruker has been in Silberstreifen. Bruker is a manufacturer of scientific instruments for molecular and materials research and has over 4,000 employees.. Mörsch In 940 Mörsch was mentioned as 'Meriske' in a document in which emperor Otto III gave the village to the Roman Catholic Diocese of Speyer. The Ministrialis of Mörsch, or the Eberstein family, ruled over the village in the 12th century. Eventually the village became the fiefdom of Margrave Hermann VIII of Baden). In 1306, he sold it to the Abbey of Herrenalb, but was able to buy it back in later years. Since 1291 most of the village belonged to the Weißenburg monastery, which then became the owner of the entire village in 1339. In 1350, Mörsch finally ended up in Baden, as part of the administrative district Mühlbürg. During the division of lands in 1535, Mörsch was handed over to the Baden-Baden family and thus belonged to the administration office of Ettlingen. After the dissolution of the administration office, Mörsch belonged to the district Karlsruhe. Neuburgweier In 1219 Neuburgweier was mentioned for the first time in an official document.
