intensifying historical stages leading to genocide. Nazi Germany's persecution of Jews, Hilberg argued, began relatively mildly through political-legal discrimination and the appropriation of Jewish assets (1933–39). Ghettoization followed: the isolation of Jews in and their confinement to Ghettoes (1939–41). The final stage, Hilberg concluded, was the destruction itself, the continental annihilation of European Jews (1941–45). In the early stages, Nazi policies targeting Jews (whether directly or through aryanization) treated them as sub-human, but with a right to live under such conditions that this status affords. In the later stages, policy was formulated to define the Jews as anti-human, with extermination being viewed as an increasingly urgent necessity. The growing Nazi momentum of destruction, began with the murdering of Jews in German and German-annexed and occupied countries, and then intensified into a search for Jews to either exterminate or use as forced labour from countries allied with Nazi Germany as well as neutral countries. The more sophisticated and organized, less clandestine part of the Nazi machinery of destruction tended to murder Jews not fit for intense manual labour immediately; later in the destruction process, more and more Jews initially labelled productive were also murdered. Eventually, Nazi compulsion for the eradication of the Jews became total and absolute, with any potentially available Jews being actively sought solely for the purpose of destruction. The seamless transformation from yet inextricable distinction between these stages, could be realized only through and put into practice by this very compounding process of an ever-growing dehumanization. As demonized as the Jews were, it seems highly unlikely that the destruction process of the later stage could take place during the time line of the stage which preceded it. An intentional destruction This dynamic reveals a spontaneity which many historians belonging to the functionalist school, following Hilberg's elaborate description, relied upon. These historians point to the more clandestine mass murder of Jews (principally in the East) and, as stated by notable functionalist, Martin Broszat, because "no general all encompassing directive for the extermination had existed." Unlike many later scholars, The Destruction does not emphasize and focus on the role of Hitler, though on this, Hilberg has shifted more towards the centre, with the third edition pointing at a less direct and systemic, more erratic and sporadic, but nonetheless pivotal, involvement by Hitler in his support for the destruction process. Hitler was a crucial impetus for the genocide, Hilberg claimed, but
