In the words of the Polish journalist and dissident, Adam Michnik, 1989 was Europe’s annus mirabilis. The peaceful revolution of that year was a miracle effected by the people in central and eastern Europe. Hardly any one (and certainly no western head of state or politician) had foreseen that a popular movement active in different countries would, in just a few months, topple socialist regimes and force the mighty Soviet Union to retreat behind the borders of Russia.
