It ended with the destruction of its synagogue on Reichspogromnacht 1938 and the subsequent deportations of Jever's Jewish inhabitants.

The Jewish community in Norden existed over a period of about 450 years from its beginnings in the 16th century until its end on April 7, 1942.

The history of the Jews on Norderney has been researched for a period of about 120 years. It begins with the record of Jewish vacationers in the seaside resort of Norderney from about 1820 and ends with the dissolution of the branch community during National Socialism around 1941. While towards the end of the 19th century bathing anti-Semitism took hold on the North Sea coast, Norderney alone had a rather liberal reputation. Jewish bathers therefore preferred this East Frisian island, so that until 1933 Norderney was known beyond the borders of Germany as the so-called Judenbad.
