Perón’s Fascist Education

Perón’s Fascist Education
European models
Juan Perón studied military organization and admired the authoritarian systems of Germany and Italy. He understood political power through discipline, hierarchy, and national mobilization.
A third force
His later vision positioned Argentina between capitalism and communism. Defeated Axis regimes became, in his imagination, a source of expertise and a possible model.
A Political Base

A Political Base
Rising power
Juan Perón built influence through labor policy and the armed forces. Eva Perón became a powerful partner in the political movement that carried him to the presidency.
Nationalist order
The new regime concentrated authority and weakened independent institutions. Its anti-American and authoritarian currents made accommodation with European extremists politically imaginable.
The Ratline System

The Ratline System
Coordinated escape
The Perón government created channels through which Nazi and Fascist fugitives could reach Argentina. Officials, diplomats, clergy, and fixers enabled travel under false identities.
Protection as policy
For Josef Mengele and others, arrival did not require a public welcome. A network of contacts, paperwork, and sympathetic authorities could provide practical shelter.
Exiles in Buenos Aires

Exiles in Buenos Aires
A crowded refuge
Buenos Aires brought together former officials, collaborators, and war criminals. Josef Mengele found employers, friends, and a social environment where his past could remain concealed.
A shared future
The expatriate network talked about returning to power in Europe. Its political fantasies were less effective than its practical aid in helping fugitives build new lives.
Protection Ends

Protection Ends
Regime collapse
A military revolt forced Juan Perón into exile. The new government pursued a campaign against Peronism and unsettled the networks that had supported Nazi immigrants.
A warning to fugitives
Josef Mengele avoided politics, but the loss of his protector made Argentina less reliable. He later fled after an abortion investigation and a report from Germany exposed his identity.
