Jews lived in Eggenburg during the entire 14th century. They suffered from the persecution that followed the host desecration accusation of Pulkau in 1338. During 1348-1378 a Jew called David continued to live in Eggenburg.
In 1408, two Jewish families resided in today’s Kremsergasse (Kremser Street), where they appear to have maintained a synagogue. In 1516 Jews who were expelled from Laibach moved to Eggenburg which was a border town where Jews were allowed to settle. In 1544 the Jews were expelled from Eggenburg too.
