During the Thirty Years' War (1620/21), four Jews were allowed to settle in the area of the German court. 
It is unknown whether Jewish persons/families actually settled.

1418 lived in Altenburg 14 men considered as taxpayers.
. Eight of them supported themselves - on a small scale - from the money trade. Also a butcher selling only to Jews (Fleischsnider of the Jews) is mentioned. In this period the Jewish families formed a small community, which probably had a prayer room (synagogue) in Johannisgasse (probably in today's Johannisstraße 31). After 1430, the Jews of Altenburg were probably expelled. In the middle of the 15th century, no Jews lived in the city anymore. 

In 1367, the Jew Merkel von Altenburg was admitted as a citizen in Erfurt. 
By 1404, another four Jews with the name of origin von Altenburg were mentioned in Erfurt.

Jäckel von Altenburg perished in Eger in the course of the persecution of the Jews during the plague. 

Isaak Seligmann ran his money trading company. At the end of the 17th century, he and other associates caused concern to the Bancoamt, as they probably circumvented it as well as imported inferior coins to Nuremberg while "carrying off" higher-quality ones, which is why the office initiated a restriction on Jewish money trading in 1680.

The medieval Jewish community had a first cemetery in the 13th century, which was probably located in the area of the still existing "Judengasse". A few remains of this cemetery are still preserved by the fact that several stones were used, for example, in the construction of the Lorenzkirche and were rediscovered (today in the funeral hall of the cemetery on Schnieglinger Straße). This first cemetery was probably destroyed during the terrible persecution in 1298.

In Nuremberg, the Orthodox Jewish association Adas Israel ("Adaß Yisroel", "Israelite Religious Society") existed in the 19th/20th century (from 1874 to 1943) under the umbrella of the liberal main congregation.
