🎯 The takeaway:
States use surveillance as a preventive tool against the empowerment of educated but excluded groups.
👉 As excluded groups gain political empowerment, surveillance may reproduce inequalities by silencing them exactly as they gain political voice.

States target those combining political capacity (education) with radical grievances (subalternity).

Across 5 indicators of political activism—voting, protests, strikes, holding political roles, and armed resistance—educated cohorts did not become more engaged.
Surveillance expanded preventively, not in reaction to mobilization.

8/ ➡️ Result 2:
Who faced the brunt of surveillance? The working class. The newly educated poor were watched longer, more harshly, and more intensively, consistently with the state fearing their empowerment.

6/ We present 3 results:
➡️ Result 1:
Municipality-cohorts exposed to more schooling were 64% more likely to be surveilled.
The effect increases as the state expands education and disappears when later reforms equalize schooling across municipalities.

5/ 🎲 The shock:
The Casati Law mandated primary schooling for 2 years everywhere but extended it for +2 years in towns >4,000 inhabitants and cohorts born post 1854.
We show the reform reduced illiteracy and use it in a difference-in-discontinuity design by population and cohort.
