In the 80s’, Mikhail Gorbachev, the last leader of the Soviet Union started the political reform to allow more autonomy to the members of the Soviet Union and its camp in Eastern Europe. The democratic movements in Eastern Europe sprang up like mushrooms. Poland held the very first democratic election and its counterparts in Eastern Europe reacted actively to it. For example, the Pan-European Picnic held by Hungary on the Austrian-Hungarian border and the Velvet Revolution in Czechoslovakia. The fall of the Berlin Wall and the reunion of East and West Germany followed was even deemed to be a success of democratisation in Eastern Europe . The four Central Europe countries that led the wave of democratisation are still working joined hands on international political occasions such as the European Union and the United Nations to advance and retreat together.
