Wilson, the Covenant and the structure of the League
What kind of organisation requires everyone to agree before it can do anything?
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 Wilson, the Covenant and the structure of the League, teach it to an AI pupil, then defend it in a marked debate — this lesson carries all three.
What the specification asks for
“Woodrow Wilson and the setting up of the League. The Covenant of the League of Nations. Membership; Assembly, Council, Secretariat, League agencies and commissions.” — examined through causation and change. Incandio is aligned to specification 4HI1; it is not published by, endorsed by or affiliated with Pearson.
1 · Understand it
Where the idea came from
The League was one answer to a question the First World War had made urgent: whether a mechanism could be built that would stop states going to war by accident, by alliance or by miscalculation. Proposals for international organisation had circulated for decades, and the war gave them a constituency.
Woodrow Wilson made the League the last of his Fourteen Points and insisted that the Covenant be written into the peace treaties themselves rather than negotiated separately afterwards. That decision had a consequence he did not intend: it tied the new organisation to a settlement that Germany regarded as a dictated peace and that many others thought unjust, so an institution presented as a fresh start was legally part of the arrangement it was supposed to improve on.
The Covenant established three principal organs. The Assembly contained every member state and met annually; the Council, with permanent and non-permanent members, met more often and handled disputes; and the Secretariat, based in Geneva, was a permanent international civil service — an innovation, since no such body had existed before.
Two features built in on the first day
The first was unanimity. Decisions of the Council required the agreement of all members present, excluding the parties to a dispute, so any member could prevent action. The rule was not an oversight: it reflected the fact that states would join an organisation that could not compel them and would not join one that could.
The second was the absence of an army. The Covenant provided for moral condemnation, then economic sanctions, and finally for the Council to recommend what military forces members should contribute. Recommend is the operative word. The League could ask its members to act and could not act itself.
The third feature was not built in but happened immediately. The United States Senate rejected the peace treaty in March 1920, so the country whose president had designed the organisation never joined it. Membership therefore began without the largest economy in the world, and the sanctions the Covenant relied on were correspondingly weaker.
Whether the design doomed it
This is the option's first genuine argument and it should be set out rather than assumed. One reading holds that the League was built to fail: unanimity meant paralysis, the absence of an army meant impotence, American absence meant sanctions could be evaded, and attaching the Covenant to Versailles meant its enemies could dismiss it as a victors' club.
The other reading holds that the design reflected what was politically obtainable in 1919. An organisation with the power to compel a great power would not have been joined by any great power, and one that ignored the peace treaties would have had no legal standing at all. On this view the League's structure is not a mistake but a description of how much international cooperation was available.
The question can be tested rather than merely argued. The League worked in the 1920s and failed in the 1930s using the same rules, which suggests that what changed was the willingness of members rather than the machinery. That is the argument to carry forward, and the next four lessons test it.
2 · Learn it — the notes
The dates that earn marks
- 1919
- The Covenant is written into the Treaty of Versailles as its first part. Why this date: It ties the League legally to a settlement its future opponents regarded as unjust.
- March 1920
- The United States Senate rejects the Treaty; America never joins. Why this date: The organisation begins without the largest economy in the world, which weakens every sanction it can impose.
- 1926
- Germany joins the League and is given a permanent Council seat. Why this date: It shows the organisation working as intended in the 1920s, which is what makes the 1930s a change rather than a constant.
The figures, and how far to trust them
- Unanimity — The rule for Council decisions, excluding parties to the dispute, which allowed any member to block action.
- No standing force — The League possessed none and could only recommend that members contribute. (It could and did organise plebiscites and administer territories using contingents supplied by members.)
- 1920 — The year the United States Senate rejected the Treaty and with it League membership.
The people to place
- Woodrow Wilson — American President; insisted the Covenant be written into the peace treaties.
- Henry Cabot Lodge — Senate leader whose opposition helped defeat American ratification.
How historians disagree
Attributed interpretations, never voiced — the AO4 seam.
- The 'doomed by design' reading: Unanimity, the absence of an army, American non-membership and attachment to Versailles were all present from the first day, so the League's failure was structural rather than a matter of what particular governments chose to do. Contested by The reading that the design was the maximum obtainable in 1919, since no great power would have joined an organisation able to coerce it — and that the same rules produced successes in the 1920s and failures in the 1930s, so the variable is the members..
What students say — and what is actually the case
Not this: The League failed because it had no army.
This: It had no army by design, and in the 1920s it settled disputes without one. The 1930s failures came where members would not apply the economic measures the Covenant did provide.
Not this: America refused to join because it was isolationist about everything.
This: The Senate's objections centred on Article 10 and the fear of being committed to foreign wars without congressional consent. The United States took part in League agencies and disarmament conferences throughout the 1920s.
Two things students merge
Blurred: The Assembly and the Council.
The distinction: The Assembly contained all members and met annually; the Council was smaller, met more often and handled disputes. Attributing Council decisions to the Assembly misdescribes how the organisation worked.
Blurred: Recommending force and having force.
The distinction: The Covenant allowed the Council to recommend what forces members should supply. Every subsequent military question about the League turns on that word, and it is the same word the United Nations Charter later replaced.
What a Grade 9 answer holds here
A Grade 9 answer treats the League's weaknesses as the price of its existence. Unanimity and the absence of an army were not oversights but the conditions on which sovereign states were willing to join at all — so the interesting question is not why an organisation designed like that failed, but why it worked at all in the 1920s and stopped working in the 1930s.
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: Unanimity named as a rule with a purpose, not as a flaw. Saying why states insisted on it converts a criticism into an explanation.
The cap that bites here: The 6-mark question is capped at 3 marks if only one difference is explained.
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 ways in which the League of Nations was different from earlier arrangements between states. [6 marks · Paper 2 Section B (a)]
- Explain TWO causes of the weaknesses of the League of Nations. [8 marks · Paper 2 Section B (b)]
- Explain TWO causes of the United States' refusal to join the League. [8 marks · Paper 2 Section B (b)]
- How significant was the structure of the League of Nations in its failure, in the years 1919–46? [16 marks · Paper 2 Section B (c)(i) or (c)(ii)]
- How far was the League of Nations doomed from the start? [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?
- Prove it — five questions on Wilson, the Covenant and the structure of the League, marked on the spot, that tell you what was missing rather than just what was wrong.
- Teach it — Explain Wilson, the Covenant and the structure of the League — 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.
- Defend it — Argue Wilson, the Covenant and the structure of the League against the historical mind with the strongest claim on it — three rounds, marked against descriptors you can read before you begin.
- Then the exam — 15 authored exam-style questions on this option, marked on Incandio with the mistake you actually made named.
