collapse of communism.

one of the main reasons why communism collapsed were the majority of citizens disagreeing on the economic system.
the people among the ussr and eastern europe were running out of money and patience.
people tore down the berlin wall because they were simply angry when they thought they couldnt get to the other side of germany.
germany was divided into two sides. both sides had different economic systems.
once they tore down the berlin wall. everyones situation got a whole lot better.
the collapse of the berlin wall and communism changed the world completely because europe wouldnt have to worry about a nuclear annihilation from the west.
