Berlin Wall
In the late 1980s, Mikhail Gorbachev said that the Soviet Union would not use the Red Army to stop the people of Eastern and Middle Europe from changing their government. After he said that, several countries began to change the way they governed their people. Hungary opened its border and people from East Germany began moving to the west through Hungary. In October 1989 mass demonstrations against the government in East Germany began. The long-time leader, Erich Honecker, resigned and was replaced by Egon Krenz a few days later. Honecker had predicted in January 1989 that the wall would stand for a "hundred more years" if the conditions which had caused its construction did not change. This did not turn out to be true.
