Collapse of Communism

Commumism collapsed in Eastern Europe and the USSR because of their ethnic groups. Yugoslavia had six groups, which caused problems. Another problem that caused Eastern Europe to collapse was Poland. They were facing economic problems. Lech Walesa was a bad leader so they took him out of office. People torn down the Berlin War because West Germany and East Germany could not cross the border. They didn't like the thought of that. West Germany and East Germany could not meet each other. Then on November 9, 1989, the Berlin Wall torn down.
