قضية دريفوس
Nordau's conversion to Zionism is in many ways typical of the rise of Zionism amongst Western European Jewry. The Dreyfus affair was central to Theodor Herzl's conviction that Zionism was now necessary. Herzl's views were formed during his time in France where he recognised the universality of antisemitism; the Dreyfus Affair cemented his belief in the failure of assimilation. Nordau also witnessed the Paris mob outside the École Militaire crying "à morts les juifs!" ("kill the Jews!").
