WW1 Causes

World War One had four main causes; Militarism, Alliances, Imperialism, and Nationalism.

Militarism: was one of the four major causes of the war. It was an “arms race”, because Britain had a large navy, Germany wanted a large navy too. Germany and France competed to build larger armies. Many nations introduced “universal conscription” (the draft), even in times of peace. For reasons of prestige and self-defense, the nation built up its army and navy, the more other nations felt they had to do the same. The expense of the “arms race” fell on civilian populations in the form of high taxes. Between 1870 and 1914, all of the major powers except Great Britain and the United States, doubled the size of their armies.

Alliances: For twenty years, the nations of Europe had been making alliances. It was thought the alliances would promote peace. Each country would be protected by others in case of war, making it foolish for one country to wage war on another. The danger of these alliances was that an argument between two countries could draw all the other nations allied with them into a fight. This is just what happened when a conflict between Austria-Hungary and Serbia led to World War I. In the summer of 1914 there were two alliances. The Triple Alliance composed of Germany, Austria-Hungary, and Italy, which opposed the Triple Entente made of Britain, France, and Russia.

Imperialism: Another cause of World War I was that European nations ruled smaller countries, called colonies, and competed with each other to conquer more colonies. Gathering colonies is known as Imperialism. The purpose of imperialism was and is to build up national wealth and influence by owning colonies. Both France and Britain had many colonies in Africa and Asia. In the 1880s and 1890s, Germany and Italy decided they wanted a colonial empire too. This global competition for land caused confrontations and conflicts in many places. For example, Great Britain almost went to war with France and the United States during the 1880s over colonies.

Nationalism: In addition to political conflicts, the causes of the war included such forces as nationalism, or pride in one’s country. The belief that one’s own nation or culture is superior to all others, nationalism led European nations to compete to build the largest army and navy. It also gave groups of subject peoples the idea of forming independent nations of their own. Serbians, Czechs, Slovaks, Bosnians and many other peoples living under the rule of the Ottoman or Austro-Hungarian Empires wanted freedom from “foreign” rule.

The Spark of the War: On 28 June 1914, Archduke Franz Ferdinand of Austria, and his wife, Sophie, a Duchess, were shot dead in Sarajevo, by Gavrilo Princip, one of the assassins in a group called the "Black Hand".  The point of the assassination was to break apart Austria-Hungary's south-Slav land so they could be combined into a Greater Serbia or a Yugoslavia. Serbian military officers supported the attack. The assassination led directly to the First World War when Austria-Hungary created an ultimatum against Serbia, which was partially rejected. Austria-Hungary then declared war, producing the outbreak of the war.
