Explain how the system of alliances divided Europe into two armed camps and turned a local crisis into a general war

What this dot point is asking

SEAB wants you to explain how the network of alliances that grew up before 1914 divided the great powers of Europe into two opposing groups, and how this division helped turn the local crisis of 1914 into a war involving the whole continent. The key task is explanation, not just listing who was allied to whom. A strong answer shows that the alliances created a situation in which a quarrel between two states could pull in many others, so that a single assassination could spark a general war.

The answer

Why countries made alliances

In the late nineteenth century the great powers of Europe sought safety in agreements with one another. An alliance was usually a promise to help an ally if it was attacked, so it was meant to be defensive. The German Chancellor Otto von Bismarck built the first network in the 1870s and 1880s to keep France isolated and to protect Germany. Each power wanted friends so that it would not face its rivals alone. The unintended result was that Europe slowly divided into two camps.

The Triple Alliance

The first camp grew out of Bismarck's diplomacy. In 1879 Germany and Austria-Hungary formed the Dual Alliance. In 1882 Italy joined, creating the Triple Alliance of Germany, Austria-Hungary and Italy. Germany and Austria-Hungary were the strong core, bound by a shared language and a fear of Russia. Italy was the weakest link, with its own quarrels with Austria-Hungary, and in the end it did not fight on their side in 1914. Still, on paper this bloc tied the two Central European empires tightly together.

The Triple Entente

The second camp formed in response. Fearing a powerful Germany, France and Russia signed the Franco-Russian Alliance in 1894, so that Germany now faced possible enemies on two sides. Britain, which had long stayed out of European alliances ("splendid isolation"), grew worried by Germany's growing navy and settled its colonial differences with France in the Entente Cordiale of 1904 and with Russia in 1907. These understandings together became known as the Triple Entente of France, Russia and Britain. An "entente" was a looser friendship than a formal alliance, but it still lined Britain up against Germany.

How the alliances divided Europe

By 1907 the great powers were arranged in two opposing groups. This had three dangerous effects. First, it created suspicion: each side watched the other and assumed the worst. Second, it made Germany feel surrounded, or "encircled", by France, Russia and Britain, which made German leaders anxious and willing to take risks to support Austria-Hungary. Third, it meant that any local dispute could spread, because an attack on one member might oblige its partners to join in.

From a local crisis to a general war

The real danger of the alliance system showed in 1914. When the heir to the Austrian throne, Archduke Franz Ferdinand, was assassinated in Sarajevo, Austria-Hungary blamed Serbia. Russia had promised to protect Serbia, so it began to mobilise. Germany, bound to Austria-Hungary, declared war on Russia and then on Russia's ally France. When Germany invaded Belgium to attack France, Britain (which had promised to defend Belgian neutrality) declared war on Germany. A quarrel in the Balkans had become a war of all the great powers within a week, because the alliances pulled each partner in.

Examples in context

Example 1. Germany's fear of encirclement. Once France and Russia allied in 1894, Germany faced possible war on two fronts, east and west. German leaders described their position as encirclement and felt they had to keep Austria-Hungary as a loyal ally at all costs. This is why, in July 1914, Germany gave Austria-Hungary strong backing (often called the "blank cheque") rather than urging restraint, which made the crisis harder to contain.

Example 2. Britain and Belgium in 1914. Britain had no formal alliance obliging it to fight for France, but it had promised in an old treaty of 1839 to protect Belgium's neutrality. When Germany invaded Belgium to reach France, Britain treated this as the trigger to enter the war. This shows how a web of older commitments, not just the main alliances, helped bring every great power in.

Q1. Name the members of the Triple Alliance and the Triple Entente. [3 marks]

• Cue. Triple Alliance: Germany, Austria-Hungary, Italy. Triple Entente: France, Russia, Britain.

Q2. Explain why Germany felt "encircled" before 1914. [5 marks]

• Cue. The Franco-Russian Alliance of 1894 meant Germany faced possible enemies on two fronts; Britain's later agreements with France and Russia completed the ring, so Germany felt surrounded by hostile powers.

Q3. "The alliance system was the most important cause of the First World War." How far do you agree? [8 marks]

• Cue. Argue the alliances were the mechanism that spread the war, but weigh them against militarism, imperial rivalry and the July Crisis before reaching a judgement on which mattered most.
