Through the analysis of the emergence of contemporary social law, Bruno Debaenst stresses the multiple links resulting from the creation of a new field in law and its specialized journals. These milestones underline how actors interact to define and manage an autonomous space in the legal culture in the making. Progressively, the two founding pillars of social law, labour law and social security law emancipated. Thus, journals follow a similar path to become distinct and specialized. Since the end of the nineteenth century, as the author lists the multiple titles, legal practitioners, lawyers and magistrates animate the journals until the Second World War. With the integration of social law in the legal curriculum, these journals received attention of Liège, Louvain and Brussels universities professors. In a way, this analysis documents how legal journals contribute to the definition of legal culture, beyond reflecting it.
