This paper demonstrates that Herzl's development of political Zionism was largely a reflection of his improved mastery of Oedipal dangers. Before his Zionism, he had been a total assimilationist. This was manifested in the nature of his disdainful attitude towards the Jewish masses and in idealization of selected non-Jews, as well as in his conflicted Jewish identity. In his thirties, various external events undermined the assimilationist approach; other events, plus ego maturation, allowed a more effective mastery of Oedipal dangers. Thus, he was able to react more appropriately and creatively to intensifying anti-Semitism by developing Zionism that reflected increased honor, manliness, and reconciliation.
