Causes of World War I

Introduction

World War I was the result of leaders' aggression towards other countries which was supported by the rising nationalism of the European nations. Economic and imperial competition and fear of war prompted military alliances and an arms race, which further escalated the tension contributing to the outbreak of war.

Nationalism

At the settlement of the Congress of Vienna in 1815, the principle of nationalism was ignored in favor of preserving the peace. Germany and Italy were left as divided states, but strong nationalist movements and revolutions led to the unification of Italy in 1861 and that of Germany in 1871. Another result of the Franco-Prussian War of 1870-71 was that France was left seething over the loss of Alsace-Lorraine to Germany, and Revanche was a major goal of the French. Nationalism posed a problem for Austria-Hungary and the Balkans, areas comprised of many conflicting national groups. The ardent Panslavism of Serbia and Russia's willingness to support its Slavic brother conflicted with Austria-Hungary's Pan-Germanism.

Imperialism

Another factor which contributed to the increase in rivalry in Europe was imperialism. Great Britain, Germany and France needed foreign markets after the increase in manufacturing caused by the Industrial Revolution. These countries competed for economic expansion in Africa. Although Britain and France resolved their differences in Africa, several crises foreshadowing the war involved the clash of Germany against Britain and France in North Africa. In the Middle East, the crumbling Ottoman Empire was alluring to Austria-Hungary, the Balkans and Russia.

Bismarck and Alliances

World War I was caused in part by the two opposing alliances developed by Bismarckian diplomacy after the Franco-Prussian War. In order to diplomatically isolate France, Bismarck formed the Three Emperor's League in 1872, an alliance between Germany, Russia and Austria-Hungary. When the French occupied Tunisia, Bismarck took advantage of Italian resentment towards France and created the Triple Alliance between Germany, Italy and Austria- Hungary in 1882. In exchange for Italy's agreement to stay neutral if war broke out between Austria-Hungary and Russia, Germany and Austria-Hungary would protect Italy from France. Russia and Austria-Hungary grew suspicious of each other over conflicts in the Balkans in 1887, but Bismarck repaired the damage to his alliances with a Reinsurance Treaty with Russia, allowing both powers to stay neutral if the other was at war.

Collapse of Bismarckian Alliances

However, after Bismarck was fired by Kaiser William II in 1890, the traditional dislike of Slavs kept Bismarck's successors from renewing the understanding with Russia. France took advantage of this opportunity to get an ally, and the Franco- Russian Entente was formed in 1891, which became a formal alliance in 1894. The Kruger telegram William II sent to congratulate the leader of the Boers for defeating the British in 1896, his instructions to the German soldiers to behave like Huns in China during the Boxer Rebellion, and particularly the large- scale navy he was building all contributed to British distrust of Germany.

As a result, Britain and France overlooked all major imperialistic conflict between them and formed the Entente Cordiale in 1904. Russia formed an Entente with Britain in 1907 after they had reached an understanding with Britain's ally Japan and William II had further alienated Russia by supporting Austrian ambitions in the Balkans. The Triple Entente, an informal coalition between Great Britain, France and Russia, now countered the Triple Alliance. International tension was greatly increased by the division of Europe into two armed camps.

Arms Race

The menace of the hostile division led to an arms race, another cause of World War I. Acknowledging that Germany was the leader in military organization and efficiency, the great powers of Europe copied the universal conscription, large reserves and detailed planning of the Prussian system. Technological and organizational developments led to the formation of general staffs with precise plans for mobilization and attack that often could not be reversed once they were begun. The German von Schlieffen Plan to attack France before Russia in the event of war with Russia was one such complicated plan that drew more countries into war than necessary.

Armies and navies were greatly expanded. The standing armies of France and Germany doubled in size between 1870 and 1914. Naval expansion was also extremely competitive, particularly between Germany and Great Britain.
