Definition: World War I from The Macquarie Dictionary

the war, conducted mainly in Europe and the Middle East, between the Triple Entente (Great Britain, France, and Russia, aided by the US, Belgium, Japan, countries of the British Empire including Australia and New Zealand, and others) and the Central Powers (Germany and Austria-Hungary, aided by Turkey and Bulgaria) from 28 July 1914, when Austria-Hungary declared war on Serbia, until the Central Powers' surrender on 11 November 1918.

A small force occupied German New Guinea at little cost in September 1914, and in November the German cruiser Emden was outfought by HMAS Sydney. On 25 April 1915 Anzacs landed on the Gallipoli peninsula. When the Anzacs were evacuated in December they joined thousands of new recruits in Egypt. The Australian Light Horse spent the rest of the war as an important part of the British force fighting Turkey in the Middle East. The other men in the AIF were formed into five infantry divisions which, from April 1916, were moved to the Western Front. The terrible losses suffered there persuaded the Australian prime minister, WM Hughes, of the need to enlarge the AIF through conscription. This proposal was twice defeated at bitterly fought referenda. In 1918, after two years of carnage, the AIF played a significant role in a series of Allied victories, including the momentous attack on the German army near Hamel on 8 August and the capture of Mont St Quentin and Péronne in September. Of the 331 000 Australians (out of a population of 4 875 000) who served overseas, about some 60 000 lost their lives and a further 152 000 were wounded; as a proportion of forces fielded, the Australian casualty rate was the highest in the British Empire. After the war, Australia secured German New Guinea as a mandated territory under the League of Nations.

Summary Article: The First World War
from World History Encyclopedia

World War I (1914-1918) has often been described as "the war to end all wars." Instead, it was the harbinger of a completely new type of warfare in which technological advances enabled belligerents to kill or injure vast numbers of soldiers and civilians and to destroy cities with greater efficiency By the end of the war in November 1918, tens of millions of people were dead for no clear purpose. Rather than ending all future warfare, the dissatisfaction that grew out of peace treaty negotiations led in great part to the outbreak of World War II in 1939.

The causes of World War I are nebulous. At the time, European foreign policy was a tangle of alliances, imperialist rivalries, nationalist chauvinism, and xenophobia mixed with memories of old slights and humiliations between nations. The last general war in Europe had taken place 99 years earlier with the defeat of Napoleon. From time to time international crises had arisen, causing nations to expect war at any moment, but these events had been resolved at least temporarily by diplomatic means.

The German empire, only in existence since 1871, was ruled by the autocratic Wilhelm II (1859-1941), who was determined that Germany would be respected and feared by the other Great Powers. This determination led to a naval buildup prior to World War I supported by successive acts of legislation, intended to create a fleet of ships that would rival Great Britain's. The result of this naval escalation was the formation of the German High Seas Fleet, followed by Great Britain's adoption of HMS Dreadnought, the first of a new and more powerful type of battleship. The British were alarmed at Germany's intentions and the balance of power in Europe. The Germans were suspicious that the Triple Entente of Britain, France, and Russia intended to encircle their nation and limit Germany's role as a European and colonial power. The military buildup that stemmed from their mutual suspicions, as well as those of the other European nations, did much to increase the likelihood that some international incident or other would lead to open warfare.

The event that served as the catalyst to the war was the June 28, 1914, assassination of the heir to the Austro-Hungarian throne, Archduke Franz Ferdinand, and his wife, Sophie, Duchess of Hohenberg, who were making an official visit to Sarajevo, the capital of Bosnia. The assassin, Gavrilo Princip, was a young Serbian nationalist affiliated with the secret society the Black Hand, a nationalist group that worked toward the goal of uniting Serbia and Bosnia-Herzegovina. Austrian officials argued that Serbia must be held accountable for the assassination, and at any rate, Austrian leaders were willing to take advantage of the opportunity to suppress Serbia's nationalist groups with force.

On July 28, 1914, Austria declared war on Serbia, reassured of the support of their German allies. Over the next few days European diplomacy broke down, the major powers mobilized their armies, and the continent was divided into armed camps. Russia sided with Serbia, and France and Great Britain sided with their ally, Russia. Germany declared war on Russia on August 1 and France on August 3. On the following morning, Germany also declared war on Belgium in order to send troops through Belgian territory on their way to France. Great Britain, which, with Prussia, France, Russia, and Austria, had guaranteed Belgium's neutrality in 1839, had pledged to support Belgium if it was invaded by Germany and resisted. Germany's invasion and Belgium's resistance brought the British into the war on August 4. Thus, Germany and Austria-Hungary supported by Turkey, became the major Central Powers; the major Allied Powers were Great Britain, France, and Russia from 1914 until the Bolshevik Revolution ended Russia's participation in late 1917, by which time the United States had abandoned its neutral stance and had entered the war on the Allied side.

At the time the war began, there was a rush for civilians to join up and go to war before it ended; popular opinion in the belligerent nations supported the idea that the war would last for only a few months. Instead, the Great War, as it was known as the time, dragged on for more than four years, and more than 65,000,000 troops were mobilized. Governments discovered that they must carefully control enlistments in order to avoid draining crucial industries of their workers, and many jobs were opened to women for the first time so that male Workers who had enlisted could be replaced, at least temporarily. The years of warfare resulted in over 37.5 million casualties, many from the new technological innovations in poison gasses, machine guns, high-explosive shells, tanks, airplanes, and artillery. These new technologies completely changed the nature of warfare to one in which large numbers of people could be injured or killed at great distances.

The Great War finally ended on November 11, 1918, when the Allies forced Germany to agree to an armistice. In January 1919 peace negotiations began in Paris, led by the "Big Four": Woodrow Wilson, president of the United States; David Lloyd George, prime minister of Great Britain; Vittorio Orlando, premier of Italy; and Georges Clemenceau, premier of France. Wilson insisted upon shaping the peace treaties according to the "Fourteen Points" he had produced the year before, an idealistic plan for "Peace Without Victory." This plan, to include freedom of the seas, open covenants between nations, self-determination for the subject peoples of the now-defunct Central Powers, and a reduction of armaments, was at odds with the postwar aims of the other Allied Powers, who were more concerned with containing Germany than with noble causes. Wilson's 14th point, a "general association of nations," led to the creation of the League of Nations.

In the long run, the resulting Versailles Treaty with Germany was almost entirely selfdefeating. While it was only one of the five peace treaties negotiated between the Allies and the former Central Powers, it was arguably the most important. The harsh terms dictated to Germany in the Versailles Treaty were a major factor in the subsequent rise of Adolf Hitler and the outbreak of World War II.
