Abstract This study delves into the intricate relationship between warfare and social rights during the Second French Republic. As recent scholarship suggests that the emergence of social rights in the 18th century involved a transition from Christian charity principles to secular obligations, primarily influenced by proponents of free markets, this research uncovers a distinct path during the July Monarchy. Here, socialists framed social rights using a unique language centered on warfare, which was overtly at odds with the prevailing free-market discourse. This transformation led to the concept of “guerre industrielle” or industrial warfare, portraying industrial workers as modern soldiers in the international economic competition among nations. Such a narrative significantly molded the political demands of the emerging French working class, focusing on securing decent employment and extending to workers the social provisions already granted to the military. These demands gained substantial momentum during the tumultuous 1848 Revolution, fueling a call for comprehensive societal transformation, emphasizing cooperative production and mutual assistance. Nevertheless, the rejection of these radical ideas was primarily attributed to the reluctance of moderate republicans to embrace the profound societal changes implied by such demands. By delving into the intricacies of this relationship, the article offers fresh insights into the development of social rights before the emergence of the Welfare State and their impact on the construction of tools of socioeconomic governance during the last two centuries.
