The Cold War

Driving Question: What were the causes of the ideological struggle of the Cold War, and how did it impact global conflicts and alliances?

How did the Cold War start? At the end of World War II, the victorious allies lost both their shared enemy and their shared purpose. The two most powerful allied nations, United States and the Soviet Union, swiftly moved to consolidate their relative positions, resulting in the division of post-war Europe. The two nations soon became known as superpowers as they avoided direct conflict by involving themselves in the opposite sides of other countries’ conflicts, while also promoting their favored ideologies of capitalism or communism.
