Despite its official break with the Zionistische Vereinigung für Deutschland and the Zionist movement in 1919, the Centralverein deutscher Staatsbürger jüdischen Glaubens (C.V.) maintained conditional neutrality toward certain Zionist organizations and projects during the Weimar Republic. This article examines the C.V.’s methods of fighting the Zionist movement in its lectures and publications during the Weimar Republic. In doing so, it argues that these measures reflected its larger determination to defend Jewish rootedness in Germany and was not based on a rejection of Zionist theory itself.
