In Diez, Jewish life has been documented since the 14th century. Since that time, Jürger Bürger shaped the cultural and economic coexistence of the townspeople unauffällig, but often they were suppressed as a minority and persecuted. 

Only from the 18th century Jüdisches life in Diez is more clearly recognizable. The Diezer Fürstenhof, for example, employed so-called Jüdische Hoffaktoren, who supplied them with luxury goods and credits. Lüb Heymann, for example, worked for Fürstin Amalie von Nassau-Oranien. He belonged at this time to the vermögendsten Diezern.

In Diersburg, which until the beginning of the 19th century belonged to the Ritterkanton Ortenau, a Jewish community existed until 1938/40. Its origin goes back to the time of the 18th century . Of the 1748 named Levi Meyer it is said that he had been living in Diersburg (previously in Schmieheim) for eleven years (i.e. since 1737); in 1738 Samuel Ellenbogen is mentioned. In 1744 there were five Jewish families in the village, in 1759 eleven families.
