The Revolutions of 1989 (also known as the Fall of Communism, the Collapse of Communism, the Revolutions of Eastern Europe and the Autumn of Nations) were the revolutions which overthrew the communist states in various Central and Eastern European countries.

The events began in Poland in 1989, and continued in Hungary, East Germany, Bulgaria, Czechoslovakia and Romania. One feature common to most of these developments was the extensive use of campaigns of civil resistance demonstrating popular opposition to the continuation of one-party rule and contributing to the pressure for change. Romania was the only Eastern Bloc country to overthrow its Communist regime violently. The Tiananmen Square protests of 1989 failed to stimulate major political changes in China. However, powerful images of courageous defiance during that protest helped to spark a precipitation of events in other parts of the globe. Among the famous anti-Communist revolutions was the fall of the Berlin Wall, which served as the symbolic gateway to German reunification in 1990.
