HistoryLesson on requestFree to read

Quick answer

The Cold War (roughly 1947–1991) was a decades-long rivalry between the United States and the Soviet Union — and their allies — fought through politics, espionage, an arms race, and proxy wars rather than direct combat. It pitted Western capitalism and democracy against Soviet communism.
