Gorbachev's decision to allow elections with a multi-party system

The establishment and control of the Soviet satellite states
This empire included Poland, Hungary, Romania, Bulgaria, Czechoslovakia and East Germany. Each had a Communist government. In the West they were called satellites because they clung closely to the Soviet Union like satellites round a planet.
several causes that led to the outbreak of the Cold War, including: tensions between the two nations at the end of World War II, the ideological conflict between both the United States and the Soviet Union, the emergence of nuclear weapons,.
Gorbachev's decision to allow elections with a multi-party system and create a presidency for the Soviet Union began a slow process of democratization that eventually destabilized Communist control and contributed to the collapse of the Soviet Union.
