# Stasi

The Ministry for State Security (German: Ministerium für Staatssicherheit, pronounced; abbreviated MfS), commonly known as the Stasi (pronounced , an abbreviation of Staatssicherheit), was the state security service and secret police of East Germany from 1950 to 1990.
The function of the Stasi in East Germany (the GDR) resembled that of the KGB in the Soviet Union,⁠ in that it served to maintain state authority and the position of the ruling party, in this case the Socialist Unity Party of Germany (SED). This was accomplished primarily through the use of a network of civilian informants who contributed to the arrest of approximately 250,000 people in East Germany. It also had a large elite paramilitary force, the Felix Dzerzhinsky Guards Regiment, that served as its armed wing. Known as "the shield and the sword of the party", the Stasi locked up opponents of the regime. Officers tortured prisoners by isolating them, depriving them of sleep and using psychological tricks such as threatening to arrest relatives.
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 in West Germany and throughout the western world; and are alleged to have occasionally cooperated with West German far-right terrorist groups, such as the Hepp-Kexel-Group.
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 from 1957 to 1989 — 32 of the 40 years of the GDR's existence. The HVA, under the leadership of Markus Wolf from 1952 to 1986, gained a reputation as one of the most effective intelligence agencies of the Cold War.
After the German reunification of 1989–1991, some former Stasi officials were prosecuted for their crimes, 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.

## Creation

The Stasi was founded on 8 February 1950. Wilhelm Zaisser was the first Minister of State Security of the GDR, and Erich Mielke was his deputy. Zaisser tried to depose SED General Secretary Walter Ulbricht after the June 1953 uprising, but was instead removed by Ulbricht and replaced with Ernst Wollweber thereafter. Following the June 1953 uprising, the Politbüro decided to downgrade the apparatus to a State Secretariat and incorporate it under the Ministry of the Interior under the leadership of Willi Stoph. The Minister of State Security simultaneously became a State Secretary of State Security. The Stasi held this status until November 1955, when it was restored to a ministry. Wollweber resigned in 1957 after clashes with Ulbricht and Erich Honecker, and was succeeded by his deputy, Erich Mielke.
In 1957, Markus Wolf became head of the Hauptverwaltung Aufklärung (HVA) (Main Reconnaissance Administration), the foreign-intelligence section of the Stasi. As intelligence chief, Wolf achieved great success in penetrating the government, political and business circles of West Germany with spies. The most influential case was that of Günter Guillaume, which led to the downfall of West German Chancellor Willy Brandt in May 1974. In 1986, Wolf retired and was succeeded by Werner Grossmann.

## Relationship with Soviet Intelligence Services

Although Mielke's Stasi was superficially granted independence in 1957, the KGB continued to maintain liaison officers in all eight main Stasi directorates at the Stasi headquarters and in each of the fifteen district headquarters around the GDR. The Stasi had also been invited by the KGB to establish operational bases in Moscow and Leningrad to monitor visiting East German tourists. Due to their close ties with Soviet intelligence services, Mielke referred to the Stasi officers as "Chekists". The KGB used 'low-visibility harassment' in order to control the population, and repress politically incorrect people and dissidents. This could involve causing unemployment, social isolation, and inducing mental and emotional health problems. Such methods formed the basis of the Stasi's use of Zersetzung (trans. decomposition) which has been considered to be a perfected version. In 1978, Mielke formally granted KGB officers in East Germany the same rights and powers that they enjoyed in the Soviet Union. The British Broadcasting Corporation noted that KGB officer (and future Russian President) Vladimir Putin worked in Dresden, from 1985 to 1989, as a liaison officer to the Stasi from the KGB. Kremlin spokesperson Dmitry Peskov responded to the reports by stating that 'The KGB and the Stasi were partner intelligence agencies'.

## Operations
### Personnel and recruitment

   The ratio for the Stasi was one secret policeman per 166 East Germans. When the regular informers are added, these ratios become much higher: In the Stasi's case, there would have been at least one spy watching every 66 citizens! When one adds in the estimated numbers of part-time snoops, the result is nothing short of monstrous: one informer per 6.5 citizens. It would not have been unreasonable to assume that at least one Stasi informer was present in any party of ten or twelve dinner guests. Like a giant octopus, the Stasi's tentacles probed every aspect of life.
Between 1950 and 1989, the Stasi employed a total of 274,000 people in an effort to root out the class enemy. In 1989, the Stasi employed 91,015 people full-time, including 2,000 fully employed unofficial collaborators, 13,073 soldiers and 2,232 officers of the GDR army, along with 173,081 unofficial informants inside the GDR and 1,553 informants in West Germany.
Regular commissioned Stasi officers were recruited from conscripts who had been honourably discharged from their 18 months' compulsory military service, had been members of the SED, had had a high level of participation in the Party's youth wing's activities and had been Stasi informers during their service in the Military. The candidates would then have to be recommended by their military unit political officers and Stasi agents, the local chiefs of the District (Bezirk) Stasi and Volkspolizei office, of the district in which they were permanently resident, and the District Secretary of the SED. These candidates were then made to sit through several tests and exams, which identified their intellectual capacity to be an officer, and their political reliability. University graduates who had completed their military service did not need to take these tests and exams. They then attended a two-year officer training programme at the Stasi college (Hochschule) in Potsdam. Less mentally and academically endowed candidates were made ordinary technicians and attended a one-year technology-intensive course for non-commissioned officers.
By 1995, some 174,000 inoffizielle Mitarbeiter (IMs) Stasi informants had been identified, almost 2.5% of East Germany's population between the ages of 18 and 60. 10,000 IMs were under 18 years of age. According to an interview with Joachim Gauck, there could have been as many as 500,000 informers. A former Stasi Colonel who served in the counterintelligence directorate estimated that the figure could be as high as 2 million if occasional informants were included. There is significant debate about how many IMs were actually employed.

### Infiltration

Full-time officers were posted to all major industrial plants (the extent of any surveillance largely depended on how valuable a product was to the economy) and one tenant in every apartment building was designated as a watchdog reporting to an area representative of the Volkspolizei (Vopo). Spies reported every relative or friend who stayed the night at another's apartment. Tiny holes were drilled in apartment and hotel room walls through which Stasi agents filmed citizens with special video cameras. Schools, universities, and hospitals were extensively infiltrated, as were organizations, such as computer clubs where teenagers exchanged Western video games.
The Stasi had formal categorizations of each type of informant, and had official guidelines on how to extract information from, and control, those with whom they came into contact. The roles of informants ranged from those already in some way involved in state security (such as the police and the armed services) to those in the dissident movements (such as in the arts and the Protestant Church). Information gathered about the latter groups was frequently used to divide or discredit members. Informants were made to feel important, given material or social incentives, and were imbued with a sense of adventure, and only around 7.7%, according to official figures, were coerced into cooperating. A significant proportion of those informing were members of the SED. Use of some form of blackmail was not uncommon. A large number of Stasi informants were tram conductors, janitors, doctors, nurses and teachers. Mielke believed that the best informants were those whose jobs entailed frequent contact with the public.
The Stasi's ranks swelled considerably after Eastern Bloc countries signed the 1975 Helsinki accords, which GDR leader Erich Honecker viewed as a grave threat to his regime because they contained language binding signatories to respect "human and basic rights, including freedom of thought, conscience, religion, and conviction". The number of IMs peaked at around 180,000 in that year, having slowly risen from 20,000 to 30,000 in the early 1950s, and reaching 100,000 for the first time in 1968, in response to Ostpolitik and protests worldwide. The Stasi also acted as a proxy for the KGB to conduct activities in other Eastern Bloc countries, such as Poland, where the Soviets were despised.
The Stasi infiltrated almost every aspect of GDR life. In the mid-1980s, a network of IMs began growing in both German states. By the time that East Germany collapsed in 1989, the Stasi employed 91,015 employees and 173,081 informants. About one out of every 63 East Germans collaborated with the Stasi. By at least one estimate, the Stasi maintained greater surveillance over its own people than any secret police force in history. The Stasi employed one secret policeman for every 166 East Germans. By comparison, the Gestapo deployed one secret policeman per 2,000 people. As ubiquitous as this was, the ratios swelled when informers were factored in: counting part-time informers, the Stasi had one agent per 6.5 people. This comparison led Nazi hunter Simon Wiesenthal to call the Stasi even more oppressive than the Gestapo. Stasi agents infiltrated and undermined West Germany's government and spy agencies.
In some cases, spouses even spied on each other. A high-profile example of this was peace activist Vera Lengsfeld, whose husband, Knud Wollenberger, was a Stasi informant.

### Zersetzung (Decomposition)

The Stasi perfected the technique of psychological harassment of perceived enemies known as Zersetzung (pronounced) – a term borrowed from chemistry which literally means "decomposition".
   The goal was to destroy secretly the self-confidence of people, for example by damaging their reputation, by organizing failures in their work, and by destroying their personal relationships. Considering this, East Germany was a very modern dictatorship. The Stasi didn't try to arrest every dissident. It preferred to paralyze them, and it could do so because it had access to so much personal information and to so many institutions.
By the 1970s, the Stasi had decided that the methods of overt persecution that had been employed up to that time, such as arrest and torture, were too crude and obvious. Such forms of oppression were drawing significant international condemnation. It was realised that psychological harassment was far less likely to be recognised for what it was, so its victims, and their supporters, were less likely to be provoked into active resistance, given that they would often not be aware of the source of their problems, or even their exact nature. International condemnation could also be avoided. Zersetzung was designed to side-track and "switch off" perceived enemies so that they would lose the will to continue any "inappropriate" activities. Anyone who was judged to display politically, culturally, or religiously incorrect attitudes could be viewed as a "hostile-negative" force and targeted with Zersetzung methods. For this reason members of the Church, writers, artists, and members of youth sub-cultures were often the victims. Zersetzung methods were applied and further developed in a "creative and differentiated" manner based upon the specific person being targeted i.e. they were tailored based upon the target's psychology and life situation.
Tactics employed under Zersetzung usually involved the disruption of the victim's private or family life. This often included psychological attacks, such as breaking into their home and subtly manipulating the contents, in a form of gaslighting i.e. moving furniture around, altering the timing of an alarm, removing pictures from walls, or replacing one variety of tea with another etc. Other practices included property damage, sabotage of cars, travel bans, career sabotage, administering purposely incorrect medical treatment, smear campaigns which could include sending falsified, compromising photos or documents to the victim's family, denunciation, provocation, psychological warfare, psychological subversion, wiretapping, bugging, mysterious phone calls or unnecessary deliveries, even including sending a vibrator to a target's wife. Increasing degrees of unemployment and social isolation could and frequently did occur due to the negative psychological, physical, and social ramifications of being targeted. Usually, victims had no idea that the Stasi were responsible. Many thought that they were losing their minds, and mental breakdowns and suicide were sometimes the result. Direct physical attacks were not part of the process, even covertly. In 2000, the research group Projektgruppe Strahlen disputed claims that the Stasi had used X-ray projection against victims. The claims persisted, however, and in 2001 the Gauck Commission, a modern government agency investigating the activities of the Stasi, claimed that 'unusual non-medical X-ray machines' found in political prisons could have been weapons and used to irradiate inmates. It was suspected that such exposure resulted in the deaths from cancer of a number of prominent dissidents.
One great advantage of the harassment perpetrated under Zersetzung was that its relatively subtle nature meant that it was able to be plausibly denied, including in diplomatic circles. This was important given that the GDR was trying to improve its international standing during the 1970s and 1980s, especially in conjunction with the Ostpolitik of West German Chancellor Willy Brandt massively improving relations between the two German states. For these political and operational reasons Zersetzung became the primary method of repression in the GDR.

## Structure

By the late 1970s and early 1980s, the Stasi had more than 100,000 employees, 11,000 of which were in the Felix Dzerzhinsky Guards Regiment, and the rest in the agency's various departments. The MfS was organized into more than 40 different departments and branches, known as Hauptabteilungen (Main Departments), each covering a different aspect of its work:
* HA I (NVA and Grenztruppen internal security)

## International operations

After German reunification, revelations of the Stasi's international activities were publicized, such as its military training of the West German Red Army Faction.
Given the close relationship between the KGB and the Stasi, their Third World operations featured a clear cut division in responsibilities. The Soviets supplied military hardware, money and military advisors, and the East Germans organized and trained secret police forces and intelligence departments. Cuba was the first main test run of setting up a new secret police and first-rate intelligence service. This operation helped to strengthen Cuban-East German relations, as well as open up the Stasi to intelligence collected by Cubans in the United States. The reputation of the Stasi was quite international, with the newly independent nation of Zanzibar making an immediate request for establishing a state security service, and East Germany being the first to recognize the country. Around the same time, Kwame Nkrumah of Ghana also made a request, saying it was critical to his Pan-African movement. The Politburo decided to help African liberation movements with military and security assistance, under the de facto supervision of Honecker. The Derg regime was given assistance to build a state security apparatus, however there were several problems with the 100 Ethiopians sent to East German institutions. As Koehler puts it, "For one thing, many of the Ethiopians lacked even an elementary education." Additionally the Stasi began training liberation movement members in Rhodesia, Mozambique, Nambia and Zimbabwe, as well as members of the ANC. The ANC operations were financed via counterfeit currencies under the auspices of Colonel Kurt Lewinsky. The Stasi was also operational in South Yemen, to keep control of the port of Aden in a friendly camp, so that it could keep weapons flowing to the PLO.

### Other examples

* Stasi officers helped in initial training and indoctrination of Egyptian State Security organizations under the Nasser government from 1957 to 58 onwards. This was discontinued by Anwar Sadat in 1976.
* The Stasi organized and extensively trained the Ba'athist Syrian Mukhabarat (secret police) under the government of Hafez al-Assad and Ba'ath Party from 1966 onwards and especially from 1973.
* The Stasi sent agents to the West as sleeper agents. For instance, sleeper agent Günter Guillaume became a senior aide to social democratic chancellor Willy Brandt, and reported about his politics and private life.
* The Stasi operated at least one brothel. Agents were used against both men and women working in Western governments. "Entrapment" was used against married men and homosexuals.
* Martin Schlaff – According to the German parliament's investigations, the Austrian billionaire's Stasi codename was "Landgraf" and registration number "3886-86". He made money by supplying embargoed goods to East Germany.
* Sokratis Kokkalis – Stasi documents suggest that the Greek businessman was a Stasi agent, whose operations included delivering Western technological secrets and bribing Greek officials to buy outdated East German telecom equipment.
* Red Army Faction (Baader-Meinhof Group) – The terrorist organization which killed dozens of West Germans and others received financial and logistical support from the Stasi, as well as shelter and new identities.
* The Stasi ordered a campaign in which cemeteries and other Jewish sites in West Germany were smeared with swastikas and other Nazi symbols. Funds were channelled to a small West German group for it to defend Adolf Eichmann.
* The Stasi channelled large amounts of money to Neo-Nazi groups in West, with the purpose of discrediting the West.
* The Stasi allowed the wanted West German Neo-Nazi Odfried Hepp to hide in East Germany and then provided him with a new identity so that he could live in the Middle East.
* The Stasi worked in a campaign to create extensive material and propaganda against Israel.
* Murder of Benno Ohnesorg – A Stasi informant in the West Berlin police, Karl-Heinz Kurras, fatally shot an unarmed demonstrator, which stirred a whole movement of Marxist radicalism, protest, and terrorist violence. The Economist describes it as "the gunshot that hoaxed a generation". The surviving Stasi Records contain no evidence that Kurras was acting under their orders when he shot Ohnesorg.
* Operation Infektion—The Stasi helped the KGB to spread HIV/AIDS disinformation that the United States had created the disease. Millions of people around the world still believe these claims.
* Sandoz chemical spill—A German television documentary reported that the KGB ordered the Stasi to sabotage the chemical factory to distract attention from the Chernobyl disaster six months earlier in Ukraine.
* Investigators have found evidence of a death squad that carried out a number of assassinations (including assassination of Swedish journalist Cats Falck) on orders from the East German government from 1976 to 1987. Attempts to prosecute members failed.
* The Stasi attempted to assassinate Wolfgang Welsch, a famous critic of the East German government. Stasi collaborator Peter Haack (Stasi codename "Alfons") befriended Welsch and then fed him hamburgers poisoned with thallium. It took weeks for doctors to find out why Welsch had suddenly lost his hair.
* Documents in the Stasi archives state that the KGB ordered Bulgarian agents to assassinate Pope John Paul II, who was known for his criticism of human rights in the Eastern Bloc, and the Stasi was asked to help with covering up traces.
* According to the National Review, a special unit of the Stasi assisted Romanian intelligence in kidnapping Romanian dissident Oliviu Beldeanu from West Germany.
* The Stasi in 1972 made plans to assist the Ministry of Public Security (Vietnam) in improving its intelligence work during the Vietnam War.
* In 1975, the Stasi recorded a conversation between senior West German CDU politicians Helmut Kohl and Kurt Biedenkopf. It was then "leaked" to Stern magazine as a transcript recorded by American intelligence. The magazine then claimed that Americans were wiretapping West Germans and the public believed the story.

## Fall of the Soviet Union

Recruitment of informants became increasingly difficult towards unification, and after 1986 there was a negative turnover rate of IMs. This had a significant impact on the Stasi's ability to survey the populace in a period of growing unrest, and knowledge of the Stasi's activities became more widespread. Stasi had been tasked during this period with preventing the country's economic difficulties becoming a political problem, through suppression of the very worst problems the state faced, but it failed to do so.
On 7 November 1989, in response to the rapidly changing political and social situation in the GDR in late 1989, Erich Mielke resigned. On 17 November 1989, the Council of Ministers (Ministerrat der DDR) renamed the Stasi the Office for National Security (Amt für Nationale Sicherheit – AfNS), which was headed by Generalleutnant Wolfgang Schwanitz. On 8 December 1989, GDR Prime Minister Hans Modrow directed the dissolution of the AfNS, which was confirmed by a decision of the Ministerrat on 14 December 1989.
As part of this decision, the Ministerrat originally called for the evolution of the AfNS into two separate organizations: a new foreign intelligence service (Nachrichtendienst der DDR) and an "Office for the Protection of the Constitution of the GDR" (Verfassungsschutz der DDR), along the lines of the West German Bundesamt für Verfassungsschutz. However, the public reaction was extremely negative, and under pressure from the "Round Table" (Runder Tisch), the government dropped the creation of the Verfassungsschutz der DDR and directed the immediate dissolution of the AfNS on 13 January 1990. Certain functions of the AfNS reasonably related to law enforcement were handed over to the GDR Ministry of Internal Affairs. The same ministry also took guardianship of remaining AfNS facilities.
When the parliament of Germany investigated public funds that disappeared after the Fall of the Berlin Wall, it found out that East Germany had transferred large amounts of money to Martin Schlaff through accounts in Vaduz, the capital of Liechtenstein, in return for goods "under Western embargo".
Moreover, high-ranking Stasi officers continued their post-GDR careers in management positions in Schlaff's group of companies. For example, in 1990, Herbert Kohler, Stasi commander in Dresden, transferred 170 million marks to Schlaff for "harddisks" and months later went to work for him. The investigations concluded that "Schlaff's empire of companies played a crucial role" in the Stasi attempts to secure the financial future of Stasi agents and keep the intelligence network alive.

## Recovery of Stasi files

During the Peaceful Revolution of 1989, Stasi offices and prisons throughout the country were occupied by citizens, but not before the Stasi destroyed a number of documents (approximately 5%) consisting of, by one calculation, 1 billion sheets of paper.

### Storming the Stasi headquarters

With the fall of the GDR, the Stasi was dissolved. Stasi employees began to destroy the extensive files and documents they held, either by hand or by using incineration or shredders. When these activities became known, a protest began in front of the Stasi headquarters. On the evening of 15 January 1990 a large crowd formed outside the gates and called for a stop to the destruction of sensitive files. The building contained vast records of personal files, many of which would supply important evidence in convicting those who had committed crimes for the Stasi. The protesters continued to grow in number until they were able to overcome the police and gain entry into the complex. Once inside, specific targets of the protesters' anger were portraits of Erich Honecker and Erich Mielke, which were torn down, trampled upon or burnt. Some Stasi employees were thrown out of upper floor windows and beaten after falling to the streets below, but there were no deaths or serious injuries. Among the protesters were former Stasi collaborators seeking to destroy incriminating documents.

### Stasi file controversy

With German reunification on 3 October 1990, a new government agency was founded, called the Federal Commissioner for the Records of the State Security Service of the former German Democratic Republic (German: Der Bundesbeauftragte für die Unterlagen des Staatssicherheitsdienstes der ehemaligen Deutschen Demokratischen Republik), officially abbreviated "BStU". There was a debate about what should happen to the files, whether they should be opened to the people or kept sealed.
Some of those who opposed opening the files cited privacy as a reason. They felt that the information in the files would lead to negative feelings about former Stasi members, and, in turn, cause violence. Pastor Rainer Eppelmann, who became Minister of Defense and Disarmament after March 1990, felt that new political freedoms for former Stasi members would be jeopardized by acts of revenge. Prime Minister Lothar de Maizière even went so far as to predict murder. They also argued against the use of the files to capture former Stasi members and prosecute them, arguing that not all former members were criminals and should not be punished solely for being a member. There were also some who believed that everyone was guilty of something. Peter-Michael Diestel, the Minister of Interior, opined that these files could not be used to determine innocence and guilt, claiming that "there were only two types of individuals who were truly innocent in this system, the newborn and the alcoholic". Others, such as West German Interior Minister Wolfgang Schäuble, believed in putting the Stasi past behind them and working on German reunification.
   But why did the Stasi collect all this information in its archives? The main purpose was to control the society. In nearly every speech, the Stasi minister gave the order to find out who is who, which meant who thinks what. He didn't want to wait until somebody tried to act against the regime. He wanted to know in advance what people were thinking and planning. The East Germans knew, of course, that they were surrounded by informers, in a totalitarian regime that created mistrust and a state of widespread fear, the most important tools to oppress people in any dictatorship.
Those on the other side of the debate argued that everyone should have the right to see their own file, and that the files should be opened to investigate former Stasi members and prosecute them, as well as prevent them from holding office. Opening the files would also help clear up some of the rumors circulating at the time. Some believed that politicians involved with the Stasi should be investigated.
The fate of the files was finally decided under the Unification Treaty between the GDR and West Germany. This treaty took the Volkskammer law further and allowed more access and greater use of the files. Along with the decision to keep the files in a central location in the East, they also decided who could see and use the files, allowing people to see their own files.
In 1992, following a declassification ruling by the German government, the Stasi files were opened, allowing individuals to gain access to their files. Timothy Garton Ash, an English historian, after reading his file, wrote The File: A Personal History.
Between 1991 and 2011, around 2.75 million individuals, mostly GDR citizens, requested to see their own files. The ruling also gave people the ability to make duplicates of their documents. Another significant question was how the media could use and benefit from the documents. It was decided that the media could obtain files as long as they were depersonalized and did not contain information about individuals under the age of 18 or former Stasi members. This ruling not only granted file access to the media, but also to schools.

### Tracking down former Stasi informers with recovered files

Some groups within the former Stasi community used threats of violence to scare off Stasi hunters, who were actively tracking down ex-members. Though these hunters succeeded in identifying many ex-Stasi, charges could not be brought against anyone merely for being a registered Stasi member. The person in question had to have participated in an illegal act. Among the high-profile individuals arrested and tried were Erich Mielke, Third Minister of State Security of the GDR, and Erich Honecker, GDR head of state. Mielke was sentenced to six years' prison for the 1931 murder of two policemen. Honecker was charged with authorizing the killing of would-be escapees along the east–west border and Berlin Wall. During his trial, he underwent cancer treatment. Nearing death, Honecker was allowed to spend his final years a free man. He died in Chile in May 1994.

### Reassembling destroyed files

Reassembling the destroyed files has been relatively easy due to the number of archives and the failure of shredding machines (in some cases, "shredding" meant tearing pages in two by hand, making the documents easily recoverable). In 1995, the BStU began reassembling the shredded documents; 13 years later, the three dozen archivists commissioned to the projects had reassembled only 327 bags. Computer-assisted data recovery is now being used to reassemble the remaining 16,000 bags – representing approximately 45 million pages. It is estimated that the task may require 30 million dollars to complete.
The CIA acquired some Stasi records during the looting of the Stasi's archives. Germany asked for their return and received some in April 2000. See also Rosenholz files.

## Museums

There are a number of memorial sites and museums relating to the Stasi in former Stasi prisons and administration buildings. In addition, offices of the Stasi Records Agency in Berlin, Dresden, Erfurt, Frankfurt-an-der-Oder and Halle (Saale) all have permanent and changing exhibitions relating to the activities of the Stasi in their region.

### Berlin

* Stasi Museum (Berlin) - This is located at Ruschestraße 103, in "Haus 1" on the former Stasi headquarters compound. The office of Erich Mielke, the head of the Stasi, was in this building and it has been preserved along with a number of other rooms. The building was occupied by protesters on 15 January 1990. On 7 November 1990, a Research Centre and Memorial was opened, which now called the Stasi Museum.
* Berlin-Hohenschönhausen Memorial - A memorial to repression during both the Soviet occupation and GDR era in a former prison that was used by both regimes. The building was a Soviet prison from 1946, and from 1951 until 1989 it was a Stasi remand centre. It officially closed on 3 October 1990, the day of German reunification. The museum and memorial site opened in 1994. It is in Alt-Hohenschönhausen, in Lichtenberg in north-east Berlin.

### Erfurt

Memorial and Education Centre Andreasstraße - a museum in Erfurt which is housed in a former Stasi remand prison. From 1952 until 1989, over 5000 political prisoners were held on remand and interrogated in the Andreasstrasse prison, which was one of 17 Stasi remand prisons in the GDR. On 4 December 1989, local citizens occupied the prison and the neighbouring Stasi district headquarters to stop the mass destruction of Stasi files. It was the first time East Germans had undertaken such resistance against the Stasi and it instigated the take over of Stasi buildings throughout the country.

### Dresden

Gedenkstätte Bautzner Straße Dresden [de] (The Bautzner Strasse Memorial in Dresden) - A Stasi remand prison and the Stasi's regional head office in Dresden. It was used as a prison by the Soviet occupying forces from 1945 to 1953, and from 1953 to 1989 by the Stasi. The Stasi held and interrogated between 12,000 and 15,000 people during the time they used the prison. The building was originally a 19th-century paper mill. It was converted into a block of flats in 1933 before being confiscated by the Soviet army in 1945. The Stasi prison and offices were occupied by local citizens on 5 December 1989, during a wave of such takeovers across the country. The museum and memorial site was opened to the public in 1994.

### Potsdam

* Gedenkstätte Lindenstraße [de] The memorial site and museum at Lindenstraße 54/55 in Potsdam, examines political persecution in the Nazi, Soviet occupation and GDR eras.

From 1933, the Nazi regime held political prisoners there, many of whom were arrested for racial reasons, for example Jews who refused to wear the yellow star on their clothing.
The Soviet administration took over the prison in 1945, also using it as a prison for holding political prisoners on remand. The Stasi then used it as a remand prison, mainly for political prisoners from 1952 until 1989. Over 6,000 people were held in the prison by the Stasi during that time. On 27 October 1989, the prison freed all political prisoners due to a nationwide amnesty. On 5 December 1989, the Stasi Headquarters in Potsdam and the Lindenstrasse Prison were occupied by protesters. From January 1990 the building was used as offices for various citizens initiatives and new political groups, such as the Neue Forum. The building was opened to the public from 20 January 1990 and people were taken on tours of the site. It officially became a Memorial site in 1995.

### Rostock

* Documentation Centre and Memorial site, former Stasi remand prison, Rostock [de] - The memorial site is in a former Stasi remand prison at Hermanstrasse 34b.

The complex was built 1958–1960. The remand prison was used by the Stasi from 1960 until 1989. About 4,900 people were held in the prison during that time, most of them were political prisoners. Most of prisoners were released after an amnesty issued on 27 October 1989. The Stasi prison in the Rostock compound was occupied by protesters on 4 December 1989 following a wave of such occupation across East Germany starting in Erfurt on the same day.
The prison closed in the early 1990s. The state of Mecklenburg-Vorpommern took ownership of it in 1998, and the memorial site and museum were established in 1999. An extensive restoration of the site began in December 2018.

## Stasi officers after the reunification
### Recruitment by Russian companies

Former Stasi agent Matthias Warnig (codename "Arthur") is currently the head of Nord Stream. Investigations have revealed that some key Gazprom Germania managers are former Stasi agents.

### Lobbying

Former Stasi officers continue to be politically active via the Gesellschaft zur Rechtlichen und Humanitären Unterstützung (GRH, Society for Legal and Humanitarian Support). Former high-ranking officers and employees of the Stasi, including the last Stasi director, Wolfgang Schwanitz, make up the majority of the organization's members, and it receives support from the German Communist Party, among others.
The impetus for the establishment of the GRH was provided by the criminal charges filed against the Stasi in the early 1990s. The GRH, decrying the charges as "victor's justice", called for them to be dropped. Today the group provides an alternative if a somewhat utopian voice in the public debate on the GDR's legacy. It calls for the closure of the Berlin-Hohenschönhausen Memorial and can be a vocal presence at memorial services and public events. In March 2006 in Berlin, GRH members disrupted a museum event; a political scandal ensued when the Berlin Senator (Minister) of Culture refused to confront them.
Behind the scenes, the GRH also lobbies people and institutions promoting opposing viewpoints. For example, in March 2006, the Berlin Senator for Education received a letter from a GRH member and former Stasi officer attacking the Museum for promoting "falsehoods, anti-communist agitation and psychological terror against minors". Similar letters have also been received by schools organizing field trips to the museum.
