The Cold War grew out of deep differences between the USA and USSR that survived their wartime alliance against Nazi Germany.
Key takeaways
- The USA was capitalist and democratic; the USSR was communist and one-party — opposed ideologies.
- The Yalta (Feb 1945) and Potsdam (July 1945) conferences revealed growing disagreement over Europe, especially Poland.
- The US atomic bomb (1945) increased Soviet distrust.
- Each side feared the other wanted to spread its system across the world.
What you need to know about Reasons for the Cold War
The Cold War was caused by ideological conflict between capitalism and communism, wartime disagreements at Yalta and Potsdam in 1945, mutual suspicion, and the shock of the atomic bomb.

Reasons for the Cold War in exam wording
| Command word / stem | What the question wants |
|---|---|
| Describe two features of… | Two supported points of knowledge, each developed |
| Explain why… | Linked reasons showing cause and effect |
| How far do you agree… | A balanced judgement with evidence on both sides, then a clear decision |
Worked exam-style stems
- “Describe two features of the disagreements at the Yalta and Potsdam conferences.” Give one feature with a supporting detail, then a second feature with its own detail — two developed points, no narrative.
- “Explain why relations between the USA and USSR broke down after 1945.” Build two or three linked reasons into a chain of cause and effect. Reward: developed causation, not a list.
