At which East Berlin theater did actors meet on 15 October 1989 to plan a reform demonstration? They met at the Deutsches Theater.

At 11 a.m. on 15 October, actors and theater employees from East Berlin gathered at the Deutsches Theater after witnessing police and Stasi violence during the GDR’s 40th-anniversary celebrations. They agreed to organize a demonstration calling for democratization and opposing government repression.

The initiative led to the Alexanderplatz demonstration on 4 November 1989, the first major East German demonstration organized by private citizens and officially permitted by the authorities. The application was submitted on 17 October, and permission was granted on 26 October.

The Deutsches Theater is easy to confuse with the Volksbühne because Volksbühne actors had held an earlier political discussion on 7 October. The final demonstration drew at least hundreds of thousands of people, though estimates ranging from about 500,000 to one million remain disputed.
