Long-term rivalry and ideological difference
How much of Soviet suspicion of the West in 1945 was ideology, and how much was memory?
Option 6 · A world divided: superpower relations, 1943–72 › Key topic 1 · Reasons for the Cold War — one of 3 lessons in this key topic. Paper 1 — depth study: A world divided: superpower relations, 1943–72, key topic 1 (30 marks: 6 · 8 · 16).
This lesson ends with Winston Churchill. Learn long-term rivalry and ideological difference, teach it, then defend it against Winston Churchill.
What the specification asks for
“Long-term rivalry between the Soviet Union and the West and the ideological differences between Communism and Capitalism” — examined through causation and continuity. Incandio is aligned to specification 4HI1; it is not published by, endorsed by or affiliated with Pearson.
1 · Understand it
Two systems that each claimed the future
Capitalism as the USA understood it meant private ownership, competitive markets, multi-party elections, a free press and the right to trade. Communism as the USSR understood it meant state ownership of the means of production, a planned economy, rule by a single party claiming to represent the working class, and no independent press or opposition.
The important point is not that they differed but that each held a theory in which the other was doomed. Marxism-Leninism held that capitalism must produce crisis and imperial war and would be replaced; American doctrine held that free markets and free elections were the natural condition to which societies return once tyranny is lifted. Neither could regard the other as a permanent legitimate arrangement, which is what made every practical dispute look like a stage in a longer contest.
The record before 1941
Soviet suspicion had specific, checkable causes. Britain, France, the United States, Japan and others sent troops to Russia during the civil war of 1918–20 in support of the Whites; the intervention was small, incoherent and unsuccessful, and it was remembered.
The USSR was excluded from the League of Nations until 1934 and treated as a pariah through the 1920s. Its offers of collective security against Germany in the 1930s were not taken up, and it was not invited to Munich in September 1938, where a state it had a treaty with was dismembered in its absence. In August 1939 it made the Nazi-Soviet Pact — a decision that looks very different depending on whether it is read as opportunism or as a state concluding that nobody would ally with it.
Western suspicion had equally specific causes: the repudiation of tsarist debts, the seizure of foreign assets, the Comintern's declared purpose of promoting revolution in other states, and the Terror and the show trials, which were reported in the West and were widely believed to be what they were.
What the alliance concealed
Between 1941 and 1945 the two were allies against Germany, and the alliance was real: Lend-Lease supplied enormous quantities of material and the Red Army destroyed the bulk of the Wehrmacht. But it was an alliance of necessity between states with no other common interest, and the disagreements inside it — over the timing of the second front, over Poland, over what would happen to Germany — were the same disagreements that became the Cold War.
So the question 'when did the Cold War begin' has answers ranging from 1917 to 1947 depending on whether the criterion is mutual hostility, the collapse of cooperation, or the formal division of Europe. Naming that range and choosing within it is a Level 4 move, and it is available cheaply on this strand.
The wartime disagreements are worth naming individually because each reappears after 1945. The second front: Stalin asked for a landing in France from 1941 and got one in June 1944, and read the delay as an intention to let the USSR bleed. Poland: the Soviet-backed Lublin committee against the London government-in-exile, sharpened by the Katyn revelations in 1943 and by the Warsaw Rising of August 1944. And the bomb: a programme Britain and the United States shared with each other and not with the ally taking the great majority of the casualties.
2 · Learn it — the notes
The dates that earn marks
- 1918–20
- Allied intervention in the Russian Civil War. Why this date: Soviet suspicion of the West has a factual basis a quarter of a century older than the Cold War.
- 1933
- The USA finally recognises the USSR, sixteen years after the revolution. Why this date: The length of the non-recognition is a measure of how abnormal the relationship was before the alliance.
- September 1938
- Munich: Czechoslovakia dismembered without Soviet participation. Why this date: The specific grievance Soviet diplomats cited for the Pact eleven months later.
- August 1939
- The Nazi-Soviet Pact. Why this date: The event that most damaged Soviet standing in the West, and it needs explaining rather than only condemning.
The figures, and how far to trust them
- About 27 million — Soviet dead in the Second World War, against roughly 420,000 American. (The comparison is the point; both figures are approximate and the Soviet total was revised upwards after 1991.)
- Twice in thirty years — Germany invaded Russia through Poland — 1914 and 1941.
- 1934 — The year the USSR was admitted to the League of Nations, fifteen years after its foundation.
The people to place
- Vladimir Lenin — Repudiated tsarist debts and founded the Comintern in 1919 to promote revolution abroad.
- Winston Churchill — Advocated intervention against the Bolsheviks in 1919 and allied with them in 1941, and said so openly.
- Vyacheslav Molotov — Soviet foreign minister; signed the Pact in 1939 and negotiated the post-war settlement.
How historians disagree
Attributed interpretations, never voiced — the AO4 seam.
- The orthodox reading: The Cold War began with Soviet expansion and the imposition of communist governments in Eastern Europe in breach of the Yalta declaration on liberated Europe. Contested by The revisionist reading, which holds that American economic and atomic power set the terms of the post-war world and treated any refusal of an open trading order as aggression, and that Soviet policy was defensive..
What students say — and what is actually the case
Not this: The Cold War began in 1945.
This: Hostility dates from 1917 and the alliance of 1941–45 is the exception in the relationship. Which date you choose depends on your criterion, and the strongest answers say so.
Not this: Soviet fear of the West was propaganda.
This: Allied troops had fought against the Bolsheviks, the USSR had been excluded from Munich, and Germany had invaded through Poland twice in thirty years at a cost of 27 million lives. A security explanation for the Eastern European buffer is the strongest case a revisionist has.
Two things students merge
Blurred: Ideological difference and ideological cause.
The distinction: Ideology explains why each side read the other's actions as threatening. It does not by itself explain the timing of any particular crisis, which usually turns on a specific decision about Germany or Eastern Europe.
Blurred: Capitalism and democracy.
The distinction: The USA supported non-democratic anti-communist regimes throughout the period. Treating the contest as democracy against dictatorship makes American policy in Iran, Guatemala and elsewhere inexplicable.
What a Grade 9 answer holds here
A Grade 9 answer treats ideology as the lens rather than the cause. It explains why each side read the other's defensive steps as offensive; the specific crises were about Germany, Poland and the bomb. Saying which work ideology is doing, and which work it is not, is what separates an explanation from a label.
3 · How it is examined
This strand is genuinely set through: Paper 1 (b) (8 marks — “Explain two effects of … on ….”); Paper 1 (c)(i) or (c)(ii) (16 marks — “'[A statement about the period.]' You may use the following in your answer: • [prompt] • [prompt]. You must also use information of your own. How far do you agree? Explain your answer.”).
What earns marks: The 1918–20 intervention. It is one clause, it is factual, and it converts 'the USSR was suspicious' into a claim with evidence behind it — which is exactly what the mark scheme means by supporting knowledge.
4 · Prove it — the questions
Answered inside Incandio, where a marker checks what a correct answer must contain and tells you which half was missing. The marking stays in the app; the questions are here.
- Explain two reasons for suspicion between the USSR and the West before 1941. [8 marks · Paper 1 (b)]
- Explain two differences between communism and capitalism as the superpowers understood them. [8 marks · Paper 1 (b)]
- Describe two features of the wartime alliance between the USSR and the West. [8 marks · Paper 1 (b)]
- 'Ideology was the main cause of the Cold War.' How far do you agree? Explain your answer. [16 marks · Paper 1 (c)(i) or (c)(ii)]
- 'Soviet policy in the years 1945–49 was defensive.' How far do you agree? Explain your answer. [16 marks · Paper 1 (c)(i) or (c)(ii)]
Decide it
This lesson feeds a Decide History judgement — a position you commit to, an objection you answer, a criterion you name: Was the Cold War anybody's fault?.
