World War I, usually called the First World War in the Commonwealth and called The Great War in its time, was one of the largest armed conflicts in history. It took place between 1914 and 1918, mainly in Europe and Africa, though a few naval battles occurred in Asia and the Pacific Ocean. The Western Front, running through Belgium and Northeastern France, was particularly destructive. Some called it "the war to end all wars", but that did not work out; it was followed only about twenty years later by the even more destructive World War II.
In the 2010s, the centennial anniversaries, and the passing away of the last veterans, have revived interest in the war. It has also gotten more attention in narrative media as the 2010s focus more on morally ambiguous characters and plots to which WWI lends itself better than WWII with its commonly accepted heroes and villains.
In 1914, Austria Archduke Franz Ferdinand was assassinated in Sarajevo by Serbia nationalists. This event sparked tension between Austria-Hungary and Serbia. As the Russian Empire backed up Serbia and Germany gave a "blank check" to Austria-Hungary, other great powers joined the conflict. Though a single event started the war, many historians argue that conflict between Europe's great powers was almost inevitable and debate over which nation is most responsible for the war is still ongoing 100 years later. World War I lives in infamy as the war that introduced weapons of mass destruction — poison gas — onto the battlefield. It was also the first major war in which the recently-invented airplane was used in combat, though not the first war to see aerial bombardment, which had been employed from balloons and airships decades earlier.
The 1919 Treaty of Versailles held the Central Powers, especially Germany, responsible for the war, and liable for what were seen as harsh reparations. Public resentment over these reparations would later be a contributing factor in the rise of Adolf Hitler and lead up to World War II. However, neither the reparations nor the territorial losses imposed on Germany were notably harsher than what Germany itself had imposed on Russia in the Treaty of Brest Litovsk a few months earlier. By contrast, Italian fascism arose over what was seen as a "vittoria mutilata" or mutilated victory by some and the territorial gains Italy made in the war were widely seen as not enough and the economic woes after the war were blamed on the Allies and numerous internal and external foes.
The war brought down several empires — Austria-Hungary, Imperial Germany, the Russian Empire and the Ottoman Empire — and sparked the formation of the Soviet Union. The defeated Central Powers were forced to give up their colonies to the Allied powers of France, the United Kingdom, Belgium, Japan, Italy and the United States. The League of Nations, which was the precursor to today's United Nations, was formed in the aftermath of the war, though its effectiveness was limited by the fact that the United States never joined and League of Nations sanctions or decisions were frequently ignored, leading to the departure or expulsion of the Soviet Union and the major Axis Powers, Germany, Italy and Japan. The tensions within Europe were only briefly resolved; World War II repeated many tragedies of the first war and introduced new horrors. The war had a severe impact on culture and literature with both significant anti-war works like All Quiet on the Western Front and glorifications of war being written by its veterans, as well as at the home front where propaganda as we know it today was produced for the first time. In Germany the budding motion picture industry was consolidated and propped up by the state into the juggernaut that would give the world German expressionism and movies like Metropolis in the interwar years. Other countries took notice, and Soviet propaganda after the war and WWII propaganda heavily relied on movies. In Italy, Benito Mussolini departed from the Socialist Party over his views on the war while an Austrian wannabe artist of the name of Adolf Hitler found his first purpose in life (and a political ideology) during his service for the Bavarian army. The war has been called "the original catastrophe of the 20th century" and many of the horrors or World War II and the Cold War would not have been possible without the catalyst of this war.
Australia and New Zealand would participate in the war as part of the British forces, most notably in the Gallipoli Campaign. While the battle resulted in a heavy defeat for the Allies against the Ottoman Empire, it galvanised the national identities of both Australia and New Zealand, and the day that their troops landed is celebrated as ANZAC Day in both countries. Canada also participated as part of the British forces, with perhaps the most famous battle being the Battle of Vimy Ridge, in which the Canadians were victorious against the Germans, which in turn galvanised the Canadian national identity.
France and Britain also used troops from their vast colonial empires, but both their contributions to the war effort, and the demands of their veterans for more of a political say were ignored after the war. In one infamous instance, a Vietnamese delegation including a man later known as Ho Chi Minh was ignored at the Paris peace conference, sowing the seed of anti-French and anti-Western resentment that lasted all the way up to the Indochina Wars.
China participated in World War I as part of the Allies from 1917-1918 by attacking the German and Austro-Hungarian concessions in Tianjin and Hankou, with the Western Allies promising to return the German concessions in China once the war was won. Moreover, while the Chinese military was not deployed overseas, many Chinese labourers served the French and British forces in Europe. However, the Western Allies reneged on their promise to China and instead awarded the German concessions in Shandong and Shanghai to Japan. This event would be seen as a national humiliation and spark off the student-led May Fourth Movement in China, which led to far-reaching reforms in Chinese society, and also to the founding of the Chinese Communist Party (CCP). The aftermath of World War I in China is covered in Chinese revolutions. China also refused to sign the peace treaties due to this humiliation - the only nation to do so.
While the popular image of the war is focused on the Western Front which remained largely static from the time the German offensive fizzled out in 1914 to the end of 1917, the war's Eastern Front remained mobile for the whole duration of the war with large territorial gains in both directions being made until Russia signed the Treaty of Brest Litovsk and left the war. The Italian front is notable for having no less than a dozen battles along the river Isonzo, all (except the last which was a successful Austrian attack) futile attempts by the Italian high command to break through the Austro-Hungarian lines which were repelled with appalling casualties on both sides. While German vessels spread throughout the world's oceans had some impressive successes early in the war, lack of secure bases and the numerical superiority of the British Royal Navy led to the capture or sinking of virtually all German vessels outside the immediate North Sea and Baltic. The bulk of the German "High Seas Fleet" meanwhile, whose construction had increased tensions between Britain and Germany in the leadup to the war, barely sailed out of their harbor and besides the inconclusive engagement near Jutland it played no role in the war other than leading to the sailors' uprising when the German High Command wanted to use their fleet for one last glorious attempt to turn the tide of a lost war and the sailors told the admiralty where they could shove that idea ultimately toppling the German Empire.
Germany held a number of colonies at the outset of the war. Given Germany's naval inferiority to the UK and the small garrisons deployed in the colonies, it was no surprise that most were in Allied hands by late 1914. However, the German force — aided by local "Askari" — in German East Africa (now Burundi, Rwanda and mainland Tanzania) managed to fight on, evade capture and even achieve small victories against overwhelming odds until 1918 only giving up after the armistice of Compiegne.
The MV Liemba — now a ferry on Lake Tanganyika and a tourist attraction — was built as an Imperial German naval vessel.
Asia beyond Turkey and the Middle East was largely spared the horrors of World War I, though the Battle of Penang was a naval battle between the German Navy and the combined French and Russian navies, in which the German cruiser SMS Emden sank the Russian cruiser Zhemchug and the French destroyer Mousquet, securing a victory for the Germans. SMS Emden would later be sunk by the Australian Navy during the Battle of Cocos. The bodies of the Russian sailors killed in the battle were buried on Penang Island and neighbouring Jerejak Island. The Zhemchug Memorial in the Western Road Cemetery at the western edge of George Town commemorates the killed Russian sailors, while the Mousquet Memorial commemorating the French sailors is located on the grounds of the Church of the Assumption. Staff from the Russian Embassy in Kuala Lumpur make a trip to Penang every year on the anniversary of the Battle of Penang to hold ceremonies commemorating their fallen sailors.
Prince Faisal, assisted by British intelligence officer T.E. Lawrence (Lawrence of Arabia), led an Arab revolt against the Ottoman Empire. They took Aqaba with a surprise attack, and later took Damascus before the British force coming from Egypt through Palestine could reach it. Britain had made promises to both local Arabs and Zionists while intending to keep neither and ended up sharing the area as colonial fiefdoms between Britain and France, causing many problems to this day.
Today it is fairly common for residents of Saudi Arabia to go out into the desert to view places where Lawrence's lads blew up the Turks' Hejaz railway which ran from Damascus to Medina. Bedouin routinely travel this area in small two-wheel-drive Toyota trucks; anyone else needs a convoy of four-wheel drive vehicles with tow chains to rescue each other when they get stuck.
The war between Austria-Hungary and Italy (1915-18) was mostly static in terms of front movement but saw brutal fighting in next to impossible conditions of a still mostly untouched high mountain range. In the latter years, mining and explosives increasingly became a means of warfare, and traces of this are still visible.
The fighting between Austria-Hungary and Italy between 1915 and 1918 was particularly fierce and fought in harsh terrain. A big part of the war effort were mines and counter-mines, and sometimes this involved literally blowing up (the tops of) mountains.
