Data and Code for: Heroes and Villains: The Effects of Heroism on Autocratic Values and Nazi Collaboration in France

We measure how a network of heroes can legitimize and diffuse extreme political behaviors. We exploit newly-declassified intelligence files, novel voting data and regimental histories to show that home municipalities of French line regiments arbitrarily rotated under Philippe Pétain's generalship through the heroic WWI battlefield of Verdun diverge politically thereafter, particularly following Pétain's own overt espousal of authoritarian views. Further, under Pétain's collaborationist Vichy regime (1940-44), they raise 7% more active Nazi collaborators per capita. These effects extend across all forms of Nazi collaboration and diffuse beyond the veterans themselves.
