The opening of a border gate between Austria and Hungary at the Pan-European Picnic on 19 August 1989, which was based on an idea by Otto von Habsburg to test the reaction of Mikhail Gorbachev, then triggered a peaceful chain reaction, at the end of which there was no longer the GDR and the Eastern Bloc had disintegrated. Because with the non-reaction of the USSR and the GDR to the mass exodus, the media-informed Eastern Europeans could feel the increasing loss of power of their governments and more and more East Germans were now trying to flee via Hungary. Erich Honecker explained to the Daily Mirror regarding the Paneuropean picnic and thus showed his people his own inaction: "Habsburg distributed leaflets far into Poland, on which the East German holidaymakers were invited to a picnic. When they came to the picnic, they were given gifts, food and Deutsche Mark, and then they were persuaded to come to the West." Then, in September, more than 13,000 East German tourists escaped through Hungary to Austria. This set up a chain of events. The Hungarians prevented many more East Germans from crossing the border and returned them to Budapest. These East Germans flooded the West German embassy and refused to return to East Germany.
