The League in the 1920s: judge methods and outcomes
Bring the enquiry together through purposes, procedures, the six disputes and five agencies without equating activity with full curriculum or institutional success.
Exam scope and assessment notes
Thirty-two introductory lessons and 96 explained tasks address revised International AS enquiry 8.2: Wilson’s programme, inclusion of the Covenant in the treaties, aims and structure; restricted and changing membership, leadership, voting processes and enforcement; all six named disputes—Åland, Teschen, Vilna, Upper Silesia, Memel and the Greek-Bulgarian border incident; and the five named agency fields—refugees, the ILO, slavery, disarmament and mandates. Four selected comparisons use labelled original paraphrases, not quotations or complete authentic four-source sets. These are introductions, not verified full historical depth or full AS or A Level preparation. Thirty-nine further introductory lessons and 117 explained tasks address enquiry 8.4 through the Dawes and Young proposals, German recovery and League entry, Geneva Protocol support and opposition, Locarno, Kellogg–Briand, the Hague settlement and evacuation, Stresemann and Briand, Italian ambitions, Soviet relations, European and Pacific limits and the immediate impact of the Wall Street Crash. Four further selected comparisons use labelled original paraphrases. Enquiries 8.1–8.4 now have introductory routes; fuller historical depth, specialist review and assessment remain unfinished. Thirty-six further introductory lessons and 108 explained tasks address enquiry 8.3: Fiume, Corfu, the Ruhr crisis and German hyperinflation; ethnic, political and economic problems in successor states and the Little Entente; Washington, Genoa, Rapallo and Lausanne; Britain, France, Germany and Italy, Soviet diplomacy and communism, US involvement and Japan’s internal and international concerns. Four further selected comparisons use labelled original paraphrases.

Paper 1 Historical sources is 75 minutes and 40 marks: both parts of one question use four sources totalling at most 600 words, at least three written and up to one visual. Part (a) compares two sources for 15 marks; part (b) uses all four and contextual knowledge for a 25-mark judgement. Paper 2 Outline study is 105 minutes and 60 marks: answer two questions from one section, both parts of each, with a 10-mark causal explanation and a 20-mark argument. These lessons are not complete papers or calibrated assessment.
Before you begin
- Distinguish a rule, a proposal, a referral, an agreement and actual implementation
- Identify the responsible institution and date; retain affected perspectives and separate contemporary statements from later editorial context
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
How should you evaluate the League’s work in the 1920s?
What you will learn
- Why use more than one criterion for effectiveness?
- Why can neither voting nor membership alone explain every case?
- How effective was the League in the 1920s?
Develop an International AS historical argument
- Write your own response before opening the model.
- Use dated evidence, identify each institution and compare rules, state cooperation and practical outcomes. Attribute claims and distinguish source passages from later editorial context.

1. How effective was the League in the 1920s?
Compare after trying
The League was effective in particular tasks during the 1920s, but its results were uneven and depended on how institutions interacted with governments and affected communities. The Covenant supplied forums, procedures and commitments that could help manage disputes. Åland and the Greek-Bulgarian case show concrete forms of accommodation or restraint, while other disputes required further arrangements or remained politically contested.
Institutional roles and stages prevent a simple scorecard. The Conference of Ambassadors, the Council and the Court did different work in the boundary cases. A referral, legal advice and an implemented arrangement are not identical outcomes. Likewise, membership and voting rules shaped possibilities without determining every result independently of leadership, resources and acceptance.
Agency work adds substantial but differentiated contributions. Identity documents, labour standards, the anti-slavery convention, disarmament preparations and mandate scrutiny each addressed particular problems through different mechanisms. Their existence did not prove universal rights or complete implementation. The strongest judgement therefore recognises practical cooperation while tracing its conditions and reach. It explains why activity could matter without declaring every dispute resolved or treating the later failures of the 1930s as proof that nothing had been achieved earlier.
Why this response fits
- Develop a reasoned answer using specific, dated evidence.
- Compare purposes, procedures, state cooperation and practical outcomes.
- This original model is not an authentic source, calibrated examination script or Cambridge grade.
Choose comparable criteria
A judgement should explain what effective means: containing violence, establishing an accepted arrangement, protecting rights, improving practical opportunities or creating continuing standards. These are related but not identical outcomes. A referral and an implemented institution should not receive the same credit merely because both involved international discussion. Compare the problem, the method used and the evidence of its consequences before choosing a verdict.
Connect structure and national action
The Covenant provided representative organs, administrative continuity, procedures and defined commitments. Membership, voting conditions and enforcement difficulties affected its reach, while leadership and willingness to act shaped credibility. None of those features explains every case alone. Procedural exceptions prevented a simple universal-veto description, and national implementation remained necessary even where a rule or recommendation was clear. Technical expertise and political support could complement each other.
Retain varied dispute and agency outcomes
Åland connected sovereignty with protections and operating self-government, while Upper Silesia required partition and continuing arrangements. Teschen and Jaworzina involved different Allied, League and judicial stages; Vilna remained contested; Memel required a later convention; and the Greek-Bulgarian response contained a particular crisis. Refugee documents, labour standards, anti-slavery commitments, disarmament preparations and mandate scrutiny made different contributions with different limits. None supplies evidence that all affected people consented or every intended benefit occurred.
Keep preparation and unfinished work explicit
These 32 introductory lessons provide 96 explained tasks and four selected comparisons across enquiry 8.2’s named headings. They do not establish full historical depth, specialist review, complete authentic four-source sets, timed-paper readiness or calibrated marking. Enquiries 8.1–8.4 now have introductory routes, including 39 further cooperation lessons and 117 explained tasks; fuller historical depth and assessment remain unfinished. The following 36 lessons introduce continuing tensions with 108 explained tasks and four selected comparisons. Existing 2026 lessons receive no automatic credit. Broad links are not a syllabus-completion percentage, and the wider Cambridge curriculum goal remains unfinished.

Worked example
Why use more than one criterion for effectiveness?
Show the worked solution
- Identify restraint and agreement.
- Identify rights and practical opportunities.
- Connect each with relevant evidence.
Answer Different activities aimed at different results, so one label can conceal the difference between a meeting, an accepted framework and a practical benefit. Several explicit criteria allow achievements and limits to be compared without counting unlike actions as identical successes.

Guided: Why use more than one criterion for effectiveness?
Give me a hint
Compare unlike outcomes before counting them.
Compare my reasoning
- Identify restraint and agreement.
- Identify rights and practical opportunities.
- Connect each with relevant evidence.
Different activities aimed at different results, so one label can conceal the difference between a meeting, an accepted framework and a practical benefit. Several explicit criteria allow achievements and limits to be compared without counting unlike actions as identical successes.
Look for these in your work
- Uses dated evidence and explains a causal or comparative connection
- Distinguishes a rule, institutional action, state cooperation and practical outcomes
Independent: Why can neither voting nor membership alone explain every case?
Give me a hint
Connect rules and reach with actual choices.
Compare my reasoning
- Identify relevant institutional conditions.
- Identify government support and acceptance.
- Compare the particular outcome.
Rules and participation shaped what was possible, but outcomes also depended on the parties, resources, leadership and the content of an arrangement. The same institution could produce different results, so one structural feature cannot replace case evidence.

Transfer: How effective was the League in the 1920s?
Give me a hint
Compare substantive contributions with their conditions and limits.
Compare my reasoning
- Explain procedures and selected dispute outcomes.
- Explain different agency contributions.
- Weigh national action and incomplete results.
The League provided mechanisms that helped contain some disputes, develop arrangements and sustain technical cooperation. Other cases remained contested, and documents or standards depended on state recognition and application. Effectiveness was therefore substantial in particular tasks but uneven, best assessed through methods, acceptance and practical outcomes rather than universal success or complete inactivity.

Common mistakes
- Thirty-two introductory lessons do not complete the 1920s topic or the qualification.
- Enquiry 8.4 has a separate introductory sequence; historical depth, specialist review and full assessment remain unfinished.
