In the 1980s the reforms of Mikhail Gorbachev and the Solidarity movement in Poland weakened the previously rigid communist system. The opening of the Iron Curtain at the Pan-European Picnic then set in motion a peaceful chain reaction, at the end of which the Eastern bloc, the Warsaw Pact and other communist states collapsed, and the Cold War ended. Germany was reunited, after the symbolic fall of the Berlin Wall in 1989 and the maps of Central and Eastern Europe were redrawn once more. This made old previously interrupted cultural and economic relationships possible, and previously isolated cities such as Berlin, Prague, Vienna, Budapest and Trieste were now again in the centre of Europe.
