This chapter begins by sketching Déat’s last days in occupied France before fleeing to Germany with the retreating Nazis. It then highlights Déat’s opportunism and his search for intellectual distinction as significant factors in his trajectory and eventual radicalization as a collaborationist fascist fully aligned with Nazism. Déat’s path from democratic socialism to fascism is summarized in terms of the practical logic of his political conversion, with the conclusion that his ultimate conversion to fascism was the culmination of his repeatedly unsuccessful attempts at political reinvention. The chapter ends by reaffirming the fundamentally discontinuous and relational character of political conversion, which is best understood in terms of what Bourdieu calls “trajectory.” Political conversions are not just individual biographical facts, nor are they passive mental processes; they are actively made by political actors within changing political fields.
