Edexcel IGCSE History: Depth Studies — Revision Notes

Condensed for the final weeks. For the full explanation, use the Depth Studies study guide.

Source evaluation — the skill the paper is built on

Assess every source using NOP:

• Nature — what kind of source is it? A diary, a speech, a cartoon, a photograph?
• Origin — who produced it, and when?
• Purpose — why was it produced? To inform, persuade, justify, record?

A biased source is not a useless source. Students routinely write “this source is biased, so it is not useful” — which inverts the skill. A propaganda poster is highly useful as evidence of what its producers wanted people to believe, even though it is a poor guide to what actually happened.

Usefulness always depends on the question asked. The same source may be unreliable for establishing facts and extremely valuable for revealing attitudes. Saying which is what earns the mark.

For “how far do the sources agree” questions: find genuine points of agreement and disagreement, explain each with reference to NOP, then reach a judgement about the extent.

Causation

Examiners reward weighing, not listing.

The structure that scores:

1. Explain how each factor contributed — not just that it did.
2. Link factors where they reinforce each other.
3. Judge which mattered most, and state the criterion for the judgement.

Distinguish the trigger from the underlying causes. The immediate event starts things, but only because the conditions made escalation possible. “The spark is not the cause” applies across the depth studies.

Recurring themes across the depth studies

Treaties and their consequences — the Treaty of Versailles was harsh enough to embitter Germany but not harsh enough to keep her weak. That single assessment answers most Versailles evaluation questions.

Why international organisations fail — the League of Nations failed for structural reasons, not one incidental one: the USA never joined, it had no army, decisions required unanimity, key powers were excluded, sanctions were weak, and Britain and France pursued their own interests. Naming several structural causes beats naming one.

Dictatorship and control — the mechanisms recur across topics: propaganda, censorship, a secret police, youth organisations, control of education, elimination of opposition, and economic policy used to buy consent. Being able to apply that framework to any regime is more useful than memorising one.

Appeasement — argue both sides. For: Britain was militarily unprepared, public opinion feared war, Versailles was widely seen as unjust, and the USSR seemed the greater threat. Against: it emboldened Hitler, sacrificed Czechoslovakia, and let Germany grow stronger relatively.

Cold War origins — ideological opposition, wartime suspicion, the atomic bomb, and disagreements at Yalta and Potsdam over Poland and Germany.

The eight depth-study options

Option	Period	Focus
1.1 French Revolution	c1780–99	Political upheaval and revolutionary change in France
1.2 Unification of Italy	1848–70	Nation-building and a unified state
1.3 Germany: Dictatorship	1918–45	The rise and consolidation of Nazi rule
1.4 India: Nationalist Challenge	1919–47	Colonial rule and the movement toward independence
1.5 USSR: Dictatorship and Conflict	1924–53	Stalinist rule and its consequences
1.6 Superpower Relations	1943–72	Cold War tensions between the USA and USSR
1.7 US Civil Rights	1945–74	The struggle for racial equality in the United States
1.8 South Africa: Apartheid	1948–94	The rise and fall of institutionalised racial segregation

Confirm which two (or more) options your centre actually teaches before revising in depth — studying the wrong option, even briefly, wastes time that could deepen knowledge of the period that will genuinely appear in the exam.

Structuring revision by option

Build separate notes for each studied option, rather than one combined set: a chronological outline of major events, the key individuals and their roles, the causes of major developments, and the consequences or significance of those developments.

Keep periods separate. Candidates lose marks by unintentionally applying facts from one Depth Study to a question about a different one — particularly where two studied options share superficial similarities, such as both involving a shift toward authoritarian rule.

Writing the answers

• Use precise evidence: names, dates, figures, treaties. “Several wars” is weak; “three wars between 1864 and 1871” is strong.
• Every paragraph should make a point, support it, and link back to the question.
• Conclusions must judge, not summarise — and say what the judgement rests on.
• Answer the question set, not the one you revised for.

Exam traps

• Dismissing a source as useless because it is biased.
• Describing a source instead of evaluating it.
• Listing causes without explaining or weighing them.
• Narrating events rather than arguing a case.
• Vague evidence with no dates or names.
• A conclusion that restates rather than judges.
• Confusing facts between two studied options that share surface similarities, such as two authoritarian-rule topics.
• Revising the wrong Depth Study option without confirming which two the centre actually teaches.

Self-test

1. What does NOP stand for, and why does purpose matter most?
2. Why is a biased source still useful?
3. What structure earns marks in a causation question?
4. Summarise the central problem with the Treaty of Versailles.
5. Give four structural reasons the League of Nations failed.
6. Name the eight Depth Study options and the period each covers.
7. Why should revision notes be built separately for each studied option rather than combined into one set?

Answers: 1. Nature, Origin, Purpose; purpose matters most because knowing why a source was created reveals what it is likely to exaggerate, omit or distort. 2. It is reliable evidence of the attitudes, intentions and beliefs of the person or group who produced it, even if unreliable about events. 3. Explain how each factor contributed, link factors together, then judge which mattered most and state the criterion for that judgement. 4. It was harsh enough to embitter Germany but not harsh enough to prevent her recovering strength. 5. The USA never joined; it had no army; decisions required unanimity; key powers were excluded; sanctions were ineffective; Britain and France pursued self-interest — any four. 6. French Revolution (c1780-99), Unification of Italy (1848-70), Germany: Dictatorship (1918-45), India: Nationalist Challenge (1919-47), USSR: Dictatorship and Conflict (1924-53), Superpower Relations (1943-72), US Civil Rights (1945-74), South Africa: Apartheid (1948-94). 7. Because candidates sometimes unintentionally apply facts from one Depth Study to a question about a different one, especially where two studied options share superficial similarities such as both involving authoritarian rule; separate notes keep the periods from bleeding into one another.
