Stasi

The Ministry for State Security, (German: Ministerium für Staatssicherheit, pronounced [minɪsˈteːʁiʊm fyːɐ̯ ˈʃtaːtsˌzɪçɐhaɪ̯t]; abbreviated as "MfS") commonly known as the Stasi (German: [ˈʃtaːziː] ⓘ), an abbreviation of Staatssicherheit, was the state security-service of East Germany (the GDR) from 1950 to 1990. The Stasi's function in East Germany resembled that of the KGB in the Soviet Union - it served as a means of maintaining state authority, i.e., as the "Shield and Sword of the Party" (German: Schild und Schwert der Partei). This was accomplished primarily through the use of a network of civilian informants. This organization contributed to the arrest of approximately 250,000 people in East Germany.[3] The Stasi also conducted espionage and other clandestine operations outside the GDR through its subordinate foreign-intelligence service, the Office of Reconnaissance, or Head Office A (German: Hauptverwaltung Aufklärung or HVA). Its operatives also maintained contacts and occasionally cooperated with West-German terrorists.[4] The Stasi had its headquarters in East Berlin, with an extensive complex in Berlin-Lichtenberg and several smaller facilities throughout the city. Erich Mielke, the Stasi's longest-serving chief, controlled the organisation for 32 (1957–1989) of the 40 years of the GDR's existence. The HVA (Hauptverwaltung Aufklärung), under Markus Wolf (in office as Leiter der HVA from 1952 to 1986), gained a reputation as one of the most effective intelligence agencies of the Cold War.[5][need quotation to verify][6] After the German reunification of 1989–1991, some Stasi officials were prosecuted for their crimes[7] and the surveillance files that the Stasi had maintained on millions of East Germans were declassified so that all citizens could inspect their personal files on request. The Stasi Records Agency maintained the files until June 2021, when they became part of the German Federal Archives.
