In his 2014 TEDSalon Berlin talk, historian Hubertus Knabe explains how the East German Stasi combined technical surveillance with a network of human informants to monitor and control ordinary people. He describes methods ranging from wiretapping and opened letters to covert disruption, while emphasizing that the figures he gives are his account in the talk, not current estimates.
What was the Stasi?
The Stasi was the East German Ministry of State Security (MfS), the state security agency commonly associated with surveillance and political repression in the German Democratic Republic. Knabe, a historian who says he was spied on by the Stasi, presents it as an organization combining intelligence gathering, secret-police authority, preliminary investigations and interrogations, and its own armed force.
How did the Stasi spy on people?
Knabe describes a mix of technical methods and human reporting. These included wiretapping, opening letters, shadowing people and taking photographs, alongside informants who reported on others. He says the aim was not only to learn what people did, but also what they thought or planned.
Knabe gives several figures in the talk to convey the reach he attributes to the system. They should be read as figures he stated in 2014, not as independently verified or present-day counts.
#1 Best Overall
| Figure stated by Knabe | What it refers to | Qualification |
|---|---|---|
| Nearly 200,000 | Constant collaborators from 1975 | Knabe’s figure in the 2014 talk; not a current estimate |
| 90,000 per day | Letters opened | Knabe’s figure in the 2014 talk |
| More than 11,000 | Soldiers in the Guards Regiment | Knabe’s figure in the 2014 talk; a separate category from informants |
What was Zersetzung?
Knabe describes Zersetzung as covert disruption meant to weaken a target’s confidence and relationships. In his account, it could involve damaging someone’s reputation or work. He argues that the possibility of informers being nearby fostered mistrust and fear, helping the state control society.
He also discusses detention and interrogation through psychological pressure and isolation, while saying detention was not always the regime’s first choice. This is Knabe’s explanation in the talk, not a complete account of every Stasi practice.
What does the talk say about the end of East Germany?
The talk turns to the GDR regime’s collapse in 1989. The available transcript excerpt says the leadership was uncertain how to respond to growing protest, but it does not provide enough detail to establish a fuller explanation of the collapse.
Knabe also references The Lives of Others, which helped make the Stasi known to a worldwide audience, and compares the informer’s role to George Orwell’s Nineteen Eighty-Four. These are cultural references, not evidence for the historical claims.

FAQ
How did the Stasi monitor ordinary East Germans?
In Knabe’s account, it used technical surveillance such as wiretapping, opening letters, shadowing and photography, as well as human informants. He says this gathering of information served the broader purpose of controlling society.
How many Stasi informers were there?
Knabe says in his 2014 talk that there were nearly 200,000 constant collaborators from 1975. That is the figure he gives in the talk; it should not be treated as a timeless or independently established count.

What did Knabe mean by “who thinks what”?
Knabe recounts an instruction to find out “who is who,” which he explains as finding out “who thinks what.” The available transcript attributes this account to Knabe; it does not identify the minister in that passage or establish the wording as an archival quotation.
Where can visitors learn more about the Stasi in Berlin?
Knabe recommends visiting the former Stasi prison in Berlin and taking a guided tour with a former political prisoner. Current tour availability and arrangements have not been verified here.
