The article analyzes a period when public officials withdrew children from the labor market and assigned them to the school system. While existing research delves into the reasons behind this process, focusing on sociopolitical reforms, economic factors and changing concepts of childhood, there is limited understanding of how working-class families responded. The article aims to fill the gap by examining the social impact on families when their children were barred from factory work by political-administrative authorities, shedding light on class formation and political subjectivation. Inspired by Jacques Rancière’s book Proletarian Nights the article specifically investigates the Swiss canton of Aargau, where the clash between industrial child labor and liberal school reforms around 1830 provides a unique perspective. The conflict prompted the mobilization of proletarian families, compelling them to organize, unite politically and collectively advocate for their children to rejoin the labor market.
