Exam scope and assessment notes
This original lesson maps Cambridge IGCSE History 0977 key question D-A for exams in 2024–2030. 0470 uses grades A*–G; 0977 uses grades 9–1 and has limited zone availability. Cambridge states that the 2029–2030 syllabus has no significant changes affecting teaching and that resources for examinations from 2024 remain suitable. This pathway maps the shared subject content across the published 2024–2030 cycles; always use the exact exam-year syllabus, exam-series prescribed topic and centre route. Cambridge 0977 is offered only in specified administrative zones and locations; confirm that your centre can enter this grading route and exam series. StudyForA explanations, examples and practice are original learning materials, not Cambridge questions, source documents, mark schemes or grades. Paper 2's prescribed topic changes each exam series: use the exact topic for your year and series from Cambridge. Source-analysis exercises here use clearly labelled, invented practice claims and do not reproduce historical documents. Component 3 is centre-approved coursework based on a depth study and needs authentic learner work, supervision, internal assessment and Cambridge moderation; StudyForA cannot conduct, authenticate or award that coursework mark. Practice feedback is formative and is not an official Cambridge grade.
Before you begin
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
How should you approach this question: Why did the war become a stalemate, become global and end in armistice?
What you will learn
- Explain the Schlieffen Plan, Belgium, the BEF, Russian mobilisation, Mons, the Marne, the race to the sea and Ypres as the Western Front became a war of attrition.
- Assess trench warfare, new weapons, Verdun and the Somme, including Haig's leadership and tactics.
- Explain the roles of British Empire, Indian and South African troops, Japan, the Arab Revolt, the war at sea, Gallipoli, the Eastern Front and civilians.
- Explain US entry, the failed German 1918 offensive, revolution in Germany and the decision to sign the Armistice.
Western Front and stalemate
The Schlieffen Plan's advance through Belgium met resistance from Belgium and the British Expeditionary Force; Russian mobilisation affected German decisions in the west. Mons, the Marne, the race to the sea and First Ypres preceded entrenched lines and a war of attrition.
Study the experience and problems of trenches, then evaluate machine guns, gas, aircraft and tanks. Verdun and the Somme show the cost and changing tactics of attrition; explain Haig's leadership and tactics at the Somme rather than relying on casualty figures alone.
Global war, other fronts and armistice
Compare British Empire troops on the Western Front using Indian and Canadian case studies; the war in German East Africa and South West Africa; Japan's siege of Tsingtao and naval protection of sea lanes; and the Arab Revolt.
Other fronts include Jutland and its consequences, convoys, submarines and the U-boat campaign, Gallipoli, the Eastern Front and Russia's defeat. The 1918 German offensive and Allied advance, American entry, the Kiel Mutiny and German Revolution, the Kaiser's abdication and the Armistice connect military exhaustion to political collapse.

Pause and explain
Which combination best explains the 1918 Armistice?
Worked example
Why did a war of movement become a stalemate on the Western Front?
Show the worked solution
- Trace the German plan and the advance through Belgium.
- Connect Allied resistance, Russian mobilisation and the Marne to the failed attempt at a quick victory.
- Explain how trenches and attrition developed and evaluate the role of technology.
Answer The German plan was disrupted by resistance in Belgium and the BEF and by the need to respond to Russian mobilisation. The Marne stopped the advance, and attempts to outflank each other led to a continuous front. Defensive firepower made attack costly, so trenches and attrition replaced rapid movement.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Explain why the Schlieffen Plan failed to deliver a quick victory in 1914.
Give me a hint
Start with one named syllabus fact, explain its effect and connect it to the question.
Compare my reasoning
- Select accurate evidence: the Marne and trench systems halted movement; the 1918 offensive failed and Germany faced revolution.
- Explain the link between that fact and the issue being tested.
- Add a second condition or limitation before reaching a short answer. A model answer follows: The German advance through Belgium faced Belgian resistance and the British Expeditionary Force, while Russian mobilisation influenced German decisions. The French and British counter-attack at the Marne halted the advance. Attempts to move around the enemy then produced the race to the sea and continuous trenches.

Look for these in your work
- Uses a relevant named fact
- Explains a cause, consequence or comparison
- Qualifies the conclusion with evidence
How important were new methods of warfare in creating stalemate?
Give me a hint
Choose a clear criterion for importance or success; compare evidence before you decide.
Compare my reasoning
- Select accurate evidence: the Marne and trench systems halted movement; the 1918 offensive failed and Germany faced revolution.
- Compare the strongest supporting evidence with a counterpoint.
- State which factor matters most, for whom and during which period. A model answer follows: Machine guns, artillery and other weapons made exposed attacks costly, helping defenders hold positions. But stalemate also followed the failure of the Schlieffen Plan, the Marne and the development of continuous trenches. Technology explains the difficulty of breaking the line, while strategy and geography explain how it formed.
Machine guns, artillery and other weapons made exposed attacks costly, helping defenders hold positions. But stalemate also followed the failure of the Schlieffen Plan, the Marne and the development of continuous trenches. Technology explains the difficulty of breaking the line, while strategy and geography explain how it formed.
Look for these in your work
- Selects evidence from the correct period
- Weighs more than one factor
- Makes a supported judgement
Original StudyForA practice claim (not a historical source): ‘The war ended because the United States entered it.’ Evaluate the claim.
Give me a hint
Treat the prompt as an interpretation to test. Identify what evidence supports it and what it leaves out.
Compare my reasoning
- Select accurate evidence: the Marne and trench systems halted movement; the 1918 offensive failed and Germany faced revolution.
- Check the claim against at least two relevant pieces of contextual knowledge.
- Explain a limitation or alternative explanation; do not treat an invented practice prompt as a real historical source. A model answer follows: US entry brought important resources and manpower, but the Armistice also followed the failure of Germany's 1918 offensive, Allied pressure, exhaustion and revolution within Germany. The end of war was not caused by one event alone. Weigh military and political evidence across 1918.

Look for these in your work
- Tests rather than repeats the claim
- Uses contextual knowledge to support or challenge it
- Explains a limitation and reaches a qualified conclusion
Common mistakes
- Describing trench life without explaining why stalemate formed
- Calling the war global only because European armies fought
- Explaining the armistice through battlefield events alone

Make it stick
Without looking, state the key question, name two syllabus facts that bear on it, and explain one limit to your first conclusion.
If you needed the solution, close it and solve the problem again from a blank page. A correct answer is stronger when you can explain the reason for each step.
