Conflict and tension: the First World War, 1894–1918 — AQA GCSE History

This topic explores the complex web of alliances, imperial rivalries, and militarism that led to the outbreak of the First World War in 1914, and then examines the key military events, strategies, and experiences of the war up to the armistice in 1918. You will study the long-term causes such as the alliance system (Triple Entente and Triple Alliance), the Moroccan Crises, and the Balkan Wars, as well as the immediate trigger: the assassination of Archduke Franz Ferdinand. The course then covers the stalemate on the Western Front, including the Schlieffen Plan, the Battle of the Marne, trench warfare, and major offensives like the Somme and Passchendaele. Finally, you will analyse how the war ended, including the impact of the Russian Revolution, the entry of the USA, and the Hundred Days Offensive.

Understanding this topic is crucial because the First World War fundamentally reshaped the modern world. It led to the collapse of empires (Austro-Hungarian, Ottoman, German, Russian), redrew national boundaries, and sowed the seeds for future conflicts, including the Second World War. The war also transformed society: it accelerated technological change (tanks, aircraft, chemical weapons), changed the role of women, and created a deep sense of disillusionment that influenced art, literature, and politics. For your GCSE, this topic tests your ability to analyse causation, evaluate significance, and use sources critically.

This topic fits within the wider AQA GCSE 'Conflict and tension' module, which examines how international relations broke down and how wars were fought. It connects to later topics on the interwar years and the Second World War, as the Treaty of Versailles (1919) and the League of Nations were direct consequences of the First World War. Mastering this unit will give you a strong foundation for understanding 20th-century history.

• →Alliance system: The Triple Entente (Britain, France, Russia) and Triple Alliance (Germany, Austria-Hungary, Italy) created a 'powder keg' where a local conflict could escalate into a general war.
• →Schlieffen Plan: Germany's strategy to avoid a two-front war by quickly defeating France through Belgium, then turning on Russia. Its failure led to trench warfare.
• →Trench warfare and stalemate: The Western Front became a brutal war of attrition with massive casualties for little territorial gain. Key battles include the Somme (1916) and Passchendaele (1917).
• →Total war: The mobilisation of entire societies, including conscription, rationing, propaganda, and women working in factories. This changed the nature of warfare.
• →The end of the war: The Russian Revolution (1917) led to Russia's withdrawal; the USA entered in 1917, providing fresh troops and resources; the German Spring Offensive (1918) failed, and the Allies' Hundred Days Offensive forced an armistice.

• Understanding of the Alliance System (Triple Alliance, Franco-Russian Alliance, Entente powers).
• Analysis of international crises (Morocco 1905/1911, Balkans 1908–1909).
• Explanation of Anglo-German rivalry (Weltpolitik, naval race, colonial tensions).
• The July Crisis and the assassination of Archduke Franz Ferdinand.
• The Schlieffen Plan and its failure (Battle of the Marne).
• Nature of trench warfare and war of attrition (Verdun, Somme, Passchendaele).
• The war at sea (Jutland, U-Boat campaign, convoys) and Gallipoli.
• Impact of the Bolshevik Revolution and Russian withdrawal.
• Reasons for and impact of US entry into the war.
• Military developments in 1918 (Spring Offensive, Hundred Days).
• Factors in Germany's defeat (blockade, armistice, leadership of Haig and Foch).

• 💡Ensure you can construct a structured analytical narrative account of key events.
• 💡Practice evaluating the utility of sources by considering their provenance and context.
• 💡Focus on explaining 'why' and 'how' rather than just describing events.
• 💡Use specific historical terminology (e.g., 'war of attrition', 'Weltpolitik', 'armistice').
• 💡Be prepared to link the actions of key individuals (e.g., Kaiser Wilhelm, Haig, Foch) to the outcomes of the war.
• 💡Use specific evidence: When writing about causes, name the alliances, crises (e.g., First Moroccan Crisis 1905, Bosnian Crisis 1908), and key individuals (e.g., Kaiser Wilhelm II, Bethmann-Hollweg). For battles, include dates, locations, casualty figures, and outcomes. This shows detailed knowledge.
• 💡Structure your answers: For causation questions, use a chain of reasoning (e.g., 'The alliance system meant that... which led to...'). For source questions, always comment on provenance (who, when, why) and cross-reference with your own knowledge. Avoid simply describing the source.
• 💡Link to the wider context: Show how events connect. For example, explain how the failure of the Schlieffen Plan led to trench warfare, which then led to the war of attrition. This demonstrates higher-level thinking and will earn you top marks.

• Confusing the causes of the war with the triggers of specific battles.
• Failing to link the failure of the Schlieffen Plan to the development of trench warfare.
• Over-simplifying the role of the alliance system as the sole cause of the war.
• Neglecting the significance of the war at sea or non-Western fronts.
• Lacking specific detail on the technological and tactical changes in 1918.
• Misconception: The assassination of Archduke Franz Ferdinand directly caused the war. Correction: It was the trigger, but the war was caused by deeper factors like alliances, nationalism, and militarism. The assassination gave Austria-Hungary an excuse to declare war on Serbia, which then activated the alliance system.
• Misconception: Trench warfare was static and unchanging. Correction: While stalemate existed, there were major offensives, new tactics (like creeping barrages and stormtroopers), and technological developments (tanks, gas, aircraft) that evolved throughout the war.
• Misconception: The war ended because Germany was defeated militarily. Correction: Germany was not decisively beaten on the battlefield; the armistice came after the German High Command realised the war was lost due to the failure of the Spring Offensive, the arrival of American troops, and the collapse of the home front (mutiny, revolution).
