On 28 June 1914 a teenage gunman shot dead an Austrian archduke in a Bosnian street. Six weeks later the most powerful nations on earth were at war. How could a single assassination drag the whole of Europe into a conflict that would kill millions? The answer is that the murder was only the spark. The dry timber had been piling up for decades: rival alliances, an arms race, clashes over colonies, and a tinderbox of nationalism in the Balkans.
This lesson uses the familiar MAIN framework, Militarism, Alliances, Imperialism and Nationalism, to make sense of the long-term causes, then traces the July Crisis step by step from Sarajevo to the outbreak of war. By the end you will be able to explain not just what happened, but how far each cause was to blame, exactly the balanced judgement the Cambridge exam rewards.
