1. Why might Czechoslovakia accept a concession it considered dangerous?
Compare after trying
The Anglo-French plan offered a way to avoid immediate confrontation by transferring mainly German districts to the Reich. Its territorial proposal included areas with over 50 per cent German inhabitants and possible adjustments through an international body with Czech representation. This was a selection principle, not a referendum result or a final border accepted by every resident.
Security was the proposed counterpart to the concession. Britain expressed readiness to join a general guarantee against unprovoked aggression, with substitution for existing reciprocal military treaties. The plan therefore asked the reduced state to rely on a different security arrangement. Neither the offer nor its peace justification established how a future guarantee would be enforced.
Acceptance must also be explained through pressure and alternatives. The proposal recognised the sacrifice but demanded a quick answer, and the subsequent Czechoslovak account described severe duress. A government could accept while considering the bargain dangerous and hoping for support against further demands. That is different from free enthusiasm, and it leaves the effectiveness of the new security system to be tested through later decisions and conduct.
Why this response fits
- Build a reasoned answer with specific evidence and an explicit connection to international relations.
- Consider the source’s author, date, audience, purpose and limits; distinguish contemporary statements from later editorial context.
- This original self-check model is not an authentic examination script, calibrated mark or Cambridge grade.
Identify who proposed the bargain
The British and French governments presented proposals to Czechoslovakia on 19 September. They argued that keeping the mainly Sudeten German districts within the state would endanger peace and Czechoslovakia’s own interests. That was their justification for a major concession to Germany, not a judgement independently accepted by every affected population. The document records the governments’ preferred solution and pressure for a prompt answer; it is not a treaty already signed by Czechoslovakia and Germany.
Read the territorial rule with its qualifications
The proposals anticipated transfer of areas with over 50 per cent German inhabitants, allowing negotiated frontier adjustments through an international body including a Czech representative. They considered direct transfer as an alternative to a plebiscite and recognised Czechoslovak objections to the wider implications of voting on such a principle. The percentage was a proposal about selecting territory, not a national referendum result or a final surveyed border. Mixed populations meant that changing a frontier could create new minority problems rather than remove them.
Explain the proposed exchange of guarantees
The plan acknowledged that a state accepting such material changes was entitled to ask about future security. Britain said it would be prepared to join an international guarantee of the new boundaries against unprovoked aggression. A principal condition was substitution of a general guarantee for existing treaties involving reciprocal military obligations. This was more than a promise to leave every previous alliance unchanged: it proposed restructuring the security system around the reduced state. An offered guarantee did not itself establish an agreed military response or prove future enforcement.
Connect urgency with unequal choice
The governments recognised the sacrifice demanded and requested an answer quickly before Chamberlain resumed talks with Hitler. Jan Masaryk’s later letter described Czechoslovak acceptance as occurring under severe pressure and extreme duress. Set that objection beside the proposal’s peace argument. A government’s formal acceptance could coexist with constrained choices and serious objections. Explaining the bargain requires its terms, the pressure and the expected security benefit, rather than treating acceptance as either free enthusiasm or evidence that no diplomatic decision occurred.

Worked example
Did the 19 September proposals leave existing reciprocal military treaties untouched?
Show the worked solution
- Identify the offered international guarantee against unprovoked aggression.
- Identify substitution for reciprocal military obligations.
- Separate the proposed arrangement from proof of enforcement.
Answer No. The plan proposed a general guarantee in place of existing treaties involving reciprocal military obligations. This was a proposed security reorganisation accompanying cession, not an undertaking that every old alliance would continue unchanged or that enforcement had already been arranged.

Guided: Did the 19 September proposals leave existing reciprocal military treaties untouched?
Give me a hint
Read the proposed guarantee and its stated condition together.
Compare my reasoning
- Identify the offered international guarantee against unprovoked aggression.
- Identify substitution for reciprocal military obligations.
- Separate the proposed arrangement from proof of enforcement.
No. The plan proposed a general guarantee in place of existing treaties involving reciprocal military obligations. This was a proposed security reorganisation accompanying cession, not an undertaking that every old alliance would continue unchanged or that enforcement had already been arranged.
Look for these in your work
- Uses the identified actor, date, document and provision accurately
- Explains a causal or comparative connection while distinguishing proposal, attributed judgement, decision and implementation
Independent: Why would moving a frontier not automatically settle the minority problem?
Give me a hint
Use the proposed threshold and the prospect of mixed populations.
Compare my reasoning
- Explain what over 50 per cent identifies.
- Recognise inhabitants outside the majority category.
- Connect adjustment and population options with the remaining problem.
An area with a German majority could still contain many Czechs, while Germans could remain elsewhere in the state. The proposal selected territory and allowed adjustments and possible population exchanges; it did not show that every resident shared one preference. A new frontier therefore changed the distribution of minority problems rather than automatically removing them.

Transfer: Why might Czechoslovakia accept a concession it considered dangerous?
Give me a hint
Connect constrained alternatives with the security bargain and pressure from partners.
Compare my reasoning
- Identify the threatened loss and the proposed guarantee.
- Use the request for a quick reply and the later account of duress.
- Distinguish constrained acceptance from enthusiasm or a guarantee already enforced.
The government faced pressure from Britain and France and the risk of confronting Germany without their support, while the proposed guarantee offered a possible security return. The later Czechoslovak account stresses duress, not enthusiasm. Acceptance can therefore be explained as a constrained decision, without assuming the guarantee was operational or the territorial loss considered harmless.
Look for these in your work
- Uses the identified actor, date, document and provision accurately
- Explains a causal or comparative connection while distinguishing proposal, attributed judgement, decision and implementation
Common mistakes
- Over 50 per cent was a proposed territorial criterion, not a vote demonstrating unanimous local or national consent.
- An international guarantee was offered as a substitute for reciprocal military obligations; practical enforcement still needs evidence.
What can you explain now?
Which explanation best fits this lesson?
Compare with the explanation
Read cession, frontier adjustment, pressure and proposed replacement guarantees as one bargain
The plan combined a large concession with a proposed reorganisation of security; the terms do not prove later enforcement.
