The Ministry for State Security (German: Ministerium für Staatssicherheit, MfS) was commonly known as "Stasi" – which is an abbreviation of the German word for State Security: "Staatssicherheit." One of its main tasks was spying on the population, mainly through a vast network of citizens turned informants, and fighting any opposition by overt and covert measures. It was also responsible for both espionage in foreign countries in the time of the the Cold War. Numerous Stasi officials were prosecuted for their crimes after the fall of the GDR in1990. After German reunification, the surveillance files that the Stasi had maintained on millions of East Germans were laid open, so that any citizen could inspect their personal file on request.
