Understanding how Jews were mobilized around a unified identity and the establishment of the State of Israel is a key point for comprehending Israel’s current policies, especially in the domain of foreign policy. This requires an exploration of the historical development of Zionism and the construction of Jewish identity by Israel's founders, which stands as one of the most profound and influential events shaping the regional dynamics of the Middle East. This study investigates how securitization mechanisms, at critical historical junctures, have influenced the evolution of Jewish collective identity, focusing on the processes and discourses through which these changes occurred. In this regard, employing a qualitative approach, the study utilizes deductive explanations grounded in Copenhagen School securitization theory. By analyzing the historical trajectories of discourses such as the two-thousand-year Jewish diaspora, the securitized pogrom issue, the Holocaust discourse, and the persistence of antisemitism, the research clearly demonstrates how these discourses, through the four-stage process of speech act, mental construction of an existential threat, recognition and acceptance of that threat by the audience, and the implementation of urgent or exceptional political measures, were strategically used by Zionist leaders and founders to shape and strengthen Jewish identity at different historical moments.
