Pinochet and the military junta established an authoritarian regime on September 11, 1973, after overthrowing socialist President Salvador Allende and his Popular Unity government. Two principles guided the new regime. The first was a complete depoliticization of society, achieved through repression, intimidation, and persecution of any opposition to the regime; political parties were banned, national electoral registries burned, and local governments and universities restructured. The second was a strict free-market economy based on prioritizing exports, the privatization of government social welfare programs, and private property.
