The community was founded in 1895 as an unofficial organization, and at its inception it was part of the Israelitische Cultusgemeinde Zürich (ICZ) . Three years later, it separated from the ICZ due to disagreements over the level of religiosity. Already in 1890, Josua Goldschmidt, Josef Ettlinger and Isidor Kohn started their own minyan in Zurich. Because of their strictly Orthodox worldview, they no longer wanted to participate in the ICZ.
