汎ヨーロッパ・ピクニック
The opening of a border gate between Austria and Hungary at the Pan-European Picnic on August 19, 1989 then set in motion a peaceful chain reaction, at the end of which there was no longer a GDR and the Eastern Bloc had disintegrated. It was the largest escape movement from East Germany since the Berlin Wall was built in 1961. But with the mass exodus at the Pan-European Picnic, the subsequent hesitant behavior of the Socialist Unity Party of East Germany and the non-intervention of the Soviet Union broke the dams. The revolts culminated with the revolt in East Germany against the communist regime of Erich Honecker. The event in East Germany developed into a popular mass revolt with sections of the Berlin Wall being torn down and East and West Berliners uniting. Gorbachev's refusal to use Soviet forces based in East Germany to suppress the revolt was seen as a sign that the Cold War had ended. Honecker was pressured to resign from office and the new government committed itself to reunification with West Germany. The communist regime of Nicolae Ceaușescu in Romania was forcefully overthrown in 1989 and Ceaușescu was executed. The other Warsaw Pact regimes also fell during the Revolutions of 1989, with the exception of the Socialist People's Republic of Albania that continued until 1992.
