The successes of the 1920s and the agencies

What do the League's successes have in common, and what does that predict about the 1930s?

Option B5 · The changing role of international organisations: the league and the UN, 1919–c2011 › Key topic 1 · The creation and successes of the League, 1919–29 — one of 2 lessons in this key topic. Paper 2 Section B — breadth study in change: The changing role of international organisations: the league and the UN, 1919–c2011, key topic 1 (30 marks: 6 · 8 · 16).

Learn the successes of the 1920s and the agencies, teach it to an AI pupil, then defend it in a marked debate — this lesson carries all three.

What the specification asks for

“Successes of the League, including the Aaland Islands (1920), Upper Silesia (1921), the Greek-Bulgarian War (1925), Refugee and Drugs Committees.” — examined through significance. Incandio is aligned to specification 4HI1; it is not published by, endorsed by or affiliated with Pearson.

1 · Understand it

Three disputes settled

The Aaland Islands, between Sweden and Finland, were disputed in 1920: the population was Swedish-speaking and the islands had been part of Finland under Russian rule. The League awarded them to Finland with guarantees of autonomy, demilitarisation and language rights. Both parties accepted.

Upper Silesia was divided between Germany and Poland in 1921 after a plebiscite produced a mixed result, with the League drawing a boundary that gave Germany most of the population and Poland most of the industry, together with a convention protecting minorities and cross-border economic arrangements.

In 1925 Greek troops crossed into Bulgaria after a frontier incident. The League ordered a withdrawal, sent observers, and required Greece to pay compensation. Greece complied, and it complained afterwards that a great power would not have been treated in the same way — a complaint that proved prophetic.

The pattern in the successes

Every one of these cases has the same shape and a candidate who spots it has the key to the whole option. In each dispute the parties were small states, neither was a great power, both preferred a settlement to a war, and the League's decision gave each side enough to accept.

That is not a criticism. Settling disputes between states that want them settled is a real function and it prevented at least one war. But it defines the limit exactly: nothing in the 1920s tested whether the League could act against a state that was determined to have what it wanted and was strong enough to take it.

The Corfu incident of 1923 is the case that shows the limit before the 1930s. After the murder of Italian officials on Greek territory, Italy bombarded and occupied Corfu; the dispute was resolved not by the League but by the Conference of Ambassadors, largely on Italian terms. A great power had refused the League's jurisdiction and had been accommodated, twelve years before Abyssinia.

The agencies and the Nansen passport

The League's other work has better claim to be its lasting achievement and is regularly omitted from answers. Its commissions and committees addressed refugees, drugs, slavery, trafficking, health and labour conditions, and several of these bodies were transferred wholesale to the United Nations in 1946.

The refugee work is the outstanding case. Fridtjof Nansen, appointed High Commissioner in 1921, faced hundreds of thousands of people displaced by the war and the Russian revolution who had no state willing to document them. The Nansen passport, introduced in 1922, was an identity certificate issued under League authority and eventually recognised by more than fifty states, which allowed stateless people to travel, work and settle.

That is an achievement no individual government produced, and it addressed a problem that only an international body could address. It is also the strongest single piece of evidence for the argument that judging these organisations by the wars they failed to stop measures the part of them that was designed to be blockable.

Two further pieces of machinery deserve a sentence because they show the same pattern. The League ran the Saar territory directly for fifteen years and then organised the plebiscite of 1935 that returned it to Germany, which is an international administration of a European territory conducted without incident. It also operated the mandates system, under which the powers administering former German and Ottoman territories were required to report annually to a permanent commission — a weak accountability, since the commission could question and not compel, and nonetheless the first time colonial administration had been required to explain itself to anybody at all.

2 · Learn it — the notes

The dates that earn marks

1920–21
The Aaland Islands and Upper Silesia are settled by League decision. Why this date: Both disputes involved small states willing to accept an award, which is the pattern in every 1920s success.
1922
The Nansen passport is introduced for stateless refugees. Why this date: It is the League's most durable single achievement and it addressed a problem no single state could solve.
1923
Italy bombards and occupies Corfu; the dispute is settled outside the League on Italian terms. Why this date: A great power refused the League's jurisdiction and was accommodated twelve years before Abyssinia.
1925
Greece withdraws from Bulgaria on League instruction and pays compensation. Why this date: Greece complained that a great power would not have been treated the same way, and the 1930s proved the complaint correct.

The figures, and how far to trust them

  • More than fifty states — Recognised the Nansen passport for stateless refugees. (Recognition varied in what it permitted, and the numbers of holders are estimates.)
  • 1921 — Nansen's appointment as High Commissioner for Refugees.
  • Small states in every case — The parties to the League's 1920s successes. (The League also administered the Saar and supervised plebiscites, which involved great-power interests indirectly.)

The people to place

  • Fridtjof Nansen — League High Commissioner for Refugees; created the passport that bears his name.

How historians disagree

Attributed interpretations, never voiced — the AO4 seam.

  • The 'quiet work' reading: The League's real achievements were the refugee settlement, the campaigns against slavery and trafficking and the health and labour work, and these are ignored because the organisation is judged only on the crises it failed to prevent. Contested by The reading that an organisation founded explicitly to prevent war must be judged principally on whether it prevented war, and that valuable side-work does not answer the charge..

What students say — and what is actually the case

Not this: The League had no successes.

This: It settled the Aaland Islands, Upper Silesia and the Greek-Bulgarian dispute, ran the Saar, and created the Nansen passport recognised by more than fifty states.

Not this: The League's failures began in the 1930s.

This: Corfu in 1923 showed a great power refusing the League's jurisdiction and being accommodated. The 1930s made the pattern impossible to ignore rather than creating it.

Two things students merge

Blurred: Settling a dispute and enforcing a decision.

The distinction: In the 1920s the League settled disputes the parties wanted settled. It never enforced a decision against a state that refused it, and the difference is what the 1930s exposed.

Blurred: The League's political work and its agencies.

The distinction: The Council handled disputes; commissions handled refugees, drugs, slavery and health, and several were transferred to the United Nations in 1946. Judging the organisation by one of the two describes half of it.

What a Grade 9 answer holds here

A Grade 9 answer notices what every 1920s success has in common. Small states, no great power involved, and both parties preferring a settlement to a war — so the League was never tested in that decade, and the Corfu incident of 1923, when Italy simply refused its jurisdiction, is the case that shows what the test would look like.

3 · How it is examined

This strand is genuinely set through: Paper 2 Section B (a) (6 marks — “Explain TWO ways in which … was different from ….”); Paper 2 Section B (b) (8 marks — “Explain TWO causes of ….”); Paper 2 Section B (c)(i) or (c)(ii) (16 marks — “How significant was … in …, in the years …? / How far were … responsible for …, in the years …? You may use the following in your answer: • [prompt] • [prompt]. You must also use information of your own.”).

What earns marks: The pattern in the successes stated once: small states, both willing. It converts a list of cases into a prediction about the 1930s.

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.

  1. Explain TWO ways in which the Greek-Bulgarian dispute of 1925 was different from the Corfu incident of 1923. [6 marks · Paper 2 Section B (a)]
  2. Explain TWO causes of the League's successes in the 1920s. [8 marks · Paper 2 Section B (b)]
  3. Explain TWO causes of the creation of the Nansen passport. [8 marks · Paper 2 Section B (b)]
  4. How significant were the League's specialised agencies, in the years 1919–46? [16 marks · Paper 2 Section B (c)(i) or (c)(ii)]
  5. How far were the League's successes in the 1920s real achievements? [16 marks · Paper 2 Section B (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: Did the League fail because of its structure or because of its members?.

Think you understand it?

Reading is the start. On Incandio a topic counts as mastered only once you have taught it and defended it — the two things a revision guide cannot ask of you.

Incandio this topic → Prove it. Teach it. Defend it. What does “Incandio it” mean?

  1. Prove it — five questions on the successes of the 1920s and the agencies, marked on the spot, that tell you what was missing rather than just what was wrong.
  2. Teach it — Explain the successes of the 1920s and the agencies — what happened, why, and what it made possible — to Ember, an AI pupil who asks the awkward question. Understanding is credited; wording is not required.
  3. Defend it — Argue the successes of the 1920s and the agencies against the historical mind with the strongest claim on it — three rounds, marked against descriptors you can read before you begin.
  4. Then the exam — 15 authored exam-style questions on this option, marked on Incandio with the mistake you actually made named.

The debate is against The Case for the Quiet Work — the case itself, argued at its strongest, because on this strand there is no single person whose position the learner has to defeat.
