This article is an attempt to study the legitimization of the Moroccan political system by constitutional jurisprudence, considered as a concrete process within the science of constitutional law, and a social field that has witnessed struggles over epistemic authority. The structure and dynamism of this scientific field, and the appropriate political context, led to its transition from profane thought to traditionalism in the wake of the conservative revolution spearheaded by moroccan young researchers. This revolution, which constituted the kingdom of the constitutionalists, will shift from a counter field to a hegemonic one. This enabled the pioneers of traditionalism to participate in the process of legitimizing the political system in Morocco, through the production of constitutional documents broadcast and infused in symbolic violence through the constitutional lesson that will turn them, with the backing of the constitutional document and academic mentoring, into a scientific habitus.
