Zersetzung is a psychological warfare technique used by the Ministry for State Security to repress political opponents in East Germany during the 1970s and 1980s. Zersetzung served to combat alleged and actual dissidents through covert means, using secret methods of abusive control and psychological manipulation to prevent anti-government activities.
The museum is divided into three levels and several portions dedicated to a portion of the Stasi history.
The use of Zersetzung is well documented due to Stasi files published after East Germany’s Wende, with several thousands or up to 10,000 individuals estimated to have become victims,:217 and 5,000 of whom sustained irreversible damage. Special pensions for restitution have been created for Zersetzung victims.
