汎ヨーロッパ・ピクニック
In 1987 Turkey formally applied to join the Community and began the longest application process for any country. After the 1988 Polish strikes and the Polish Round Table Agreement, the first small signs of opening in Central Europe appeared. 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. Otto von Habsburg and Imre Pozsgay saw the event as an opportunity to test Mikhail Gorbachev`s reaction to an opening of the Iron Curtain. In particular, it was examined whether Moscow would give the Soviet troops stationed in Hungary the command to intervene. 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. So the bracket of the Eastern Bloc was broken and as a result the Berlin Wall fell together with the whole Iron Curtain. Germany reunified and the door to enlargement to the former Eastern Bloc was opened (See also: Copenhagen Criteria).
