Seguro Obrero massacre

1938 retaliation by Chilean authorities against a failed coup by National Socialists

The Seguro Obrero massacre occurred on September 5, 1938, and was the Chilean government's response to an attempted coup d'état by the National Socialist Movement of Chile (MNSCh), whose members were known at the time as Nacistas ("Nazis"). Known for their affinity towards violence in order to attain their goals, their occupation of the central building at the University of Chile and the Seguro Obrero building was responded to quickly and harshly by the Chilean government and the carabineros. After the failed coup, which involved a stand-off and shootout where one Nacista and one police officer (carabinero) were killed, the Nacistas surrendered after receiving assurances of not being harmed. However, the police then broke their promise and summarily executed the Nacistas, allegedly under the orders of President Arturo Alessandri. A total of 59 Nacistas were massacred, with only four of the rebels managing to escape.
