During a recent stay in Berlin, I visited the old headquarters of the East German Ministry of State Security, better known as the Stasi. The building, in a suitably bleak part of what used to be East Berlin, is now a museum devoted to the communist surveillance state. The upper floors display some of the tools of that surveillance — miniature cameras, listening devices, files on everything — that the German Democratic Republic used to control every aspect of its citizens’ lives.

But the first floor of the Stasi Museum is not about spying. Instead, it is devoted to the propaganda that East German bureaucrats used to foster socialist consciousness in an unwilling public. One display explains the GDR’s efforts in the 1950s to politicize what in the past had been family and religious occasions. The state sought to transform weddings, confirmations, and other personal events into “socialist celebrations,” to be “committed collectively and aimed at a confession to socialism,” according to the awkward English translation of the exhibit.
