Which East Berlin square hosted the huge reform demonstration on 4 November 1989?

The huge reform demonstration on 4 November 1989 was held at Alexanderplatz in East Berlin.

Known as the Alexanderplatz demonstration, it was organized by actors and employees of East Berlin theaters rather than by the East German state. The authorities officially permitted it, making it the first state-approved demonstration in East Germany organized by private individuals. Protesters called for freedom of speech, freedom of assembly, democratic reform, and an end to political repression.

The event began as a march and culminated at Alexanderplatz, a major public square in the center of East Berlin. Estimates of the crowd vary widely: organizers and contemporary reports cited roughly 500,000 to 1 million people, while some later historians proposed lower figures. Whatever the exact number, it was among the largest demonstrations in East German history.

The rally took place just five days before the Berlin Wall opened. Speakers included writers, actors, opposition figures, and even representatives of the ruling establishment. Unlike later reunification rallies, the main demands on 4 November focused on democratizing East Germany rather than immediately abolishing it or merging it with West Germany.
