Nearly every country today has universal primary education. But why did governments in the West decide to provide education to all children in the first place? The introduction of broadly accessible primary education was not mainly a response to industrialization, or fueled by democratic ideals, or even aimed at eradicating illiteracy or improving skills. It was motivated instead by elites’ fear of the masses—and the desire to turn the “savage,” “unruly,” and “morally flawed” children of the lower classes into well-behaved future citizens who would obey the state and its laws.
