The Allies of World War I Allied Powers (led by Britain, France and until 1917 Russia , and, after 1917, the United States) defeated the Central Powers (led by the German Empire, Austria-Hungary and the Ottoman Empire). The war caused the collapse of four empires and a radical change in the map of Europe and the Middle East. Before 1917 the Allied powers are sometimes referred to as the Triple Entente, and the Central Powers are sometimes referred to as the Triple Alliance.

Introduction
Much of the fighting in World War I took place along the Western Front (WWI) Western Front, embodied within a system of opposing manned trenches and fortifications (separated by a "No man's land") running from the North Sea to the border of Switzerland. Hostilities were also prosecuted, however, by more dynamic invasion and battle, by fighting at sea and - for the first time - in and out from the air. More than 9 million soldiers died on the various battlefields, and nearly that many more in the participating countries' home fronts on account of food shortages and genocide committed under the cover of various civil wars and internal conflicts. In World War I, only some 5% of the Casualty (person) casualties (directly caused by the war) were civilian - in World War II, this figure approached 50%. Ultimately, World War I created a decisive break with the old New World Order (political) world order that had emerged after the Napoleonic Wars, as modified by the mid-19th century national revolutions, the processes of European national unification and European colonialism. Three European land empires were shattered and subsequently dismembered to varying degrees: the German Empire German, the Austria-Hungary Austro-Hungarian and the Imperial Russia Russian. In the Balkans and the Middle East, the Ottoman Empire experienced the same fate. Three European imperial Dynasty dynasties, represented by the Hohenzollern, the Habsburg and the Romanov families in Germany, Austria-Hungary and Russia respectively, also fell during the war. The failure of the Russian war effort led to the fall of the Czars's system; it was replaced briefly by a liberal regime that in turn fell to the Bolsheviks in late 1917 in the Russian Revolution of 1917. They made peace on Germany's terms. After a complex civil war the Communists won and created the Union of Soviet Socialist Republics. In the Middle East, the Ottoman Empire was replaced by the Republic of Turkey and a number of successor states and territories throughout the Middle East controlled by Britain and France. In Central Europe, the new states of Czechoslovakia, Finland, Latvia, Lithuania, Estonia and Yugoslavia were born and Austria, Hungary and Poland were re-created. Shortly after the war, in 1923, Fascists came to power in Italy; in 1933, 14 years after the war, Nazism took over Germany. Problems unresolved or created by the war would be highly important factors in the outbreak, within 20 years, of World War II.

Causes
{{Main|Causes of World War I}} Image:Sarajevo Attentat.jpg thumb|200px|right|The assassination in Sarajevo; this event proved to be the catalyst for a wide-ranging war in Europe On June 28, 1914, Archduke Franz Ferdinand was assassinated by a team of Serbian nationalists while he was in Sarajevo to assert imperial authority over Bosnia. This assassination triggered the cascade of events that quickly produced war, but the causes of the war were multiple and complex. Historians and political scientists have grappled with this question for nearly a century without reaching a consensus. Some of the more prominent explanations are outlined below.

=Versailles: Sole guilt of Austria-Hungary and Germany
= Early explanations of the causes of World War I, prominent in the 1920s, stressed the official version of responsibility that was set forth in the The War Guilt clause, or Article 231 of the Treaty of Versailles and Treaty of Trianon. This explanation of the causes of the war predictably tended to alleviate the guilt of the "victorious" countries, which drafted and ratified the treaty, over what some consider to be a costly and fruitless bloodbath. The explanation of events in the clause was not baseless; it is true that Austria, backed by Berlin, attacked Serbia on July 29 and Germany invaded Belgium on August 3, in accordance with the Schlieffen Plan. Though drastically simplified, the guilt clause clearly portrayed Germany and Austria-Hungary as the aggressors, and therefore, those bearing responsibility for hostilities. Not surprisingly, this resulted in the humiliation of Germany. The treaty included the demand that Germany pay all the war costs (including pensions) of the Allies. This directly affected the global economy and indirectly contributed to the Great Depression. The War Guilt clause was a major issue in domestic German politics in the 1920s and 1930s and worked to the favor of the Nazis, who rode the coattails of German nationalism all the way to the Reichstag. The two became largely indistinguishable. Many prominent British figures, especially economist John Maynard Keynes, rejected the Guilt clause that the French avidly supported. Since 1960, the idea that Germany was primarily responsible was revived by academics such as Fritz Fischer, Imanuel Geiss, Hans-Ulrich Wehler, Wolfgang Mommsen, and V.R. Berghahn. Fischer, for example, emphasized that Germany wanted to control most of Europe or at the very least, unite it ''through'' Germany. However, as Fischer points out, diplomatic efforts to do so often centered around Anglo-Germanic cooperation. Likewise, aside from small Germanic territorial enclaves in Belgium, it is unclear exactly what the Germans had to gain in a war, whereas the French and British had territorial and economic-related ambitions, respectively.

=Arms Races and Alliances
= Another cause of the war was the building of alliances and the related arms race. An example of the latter is the launch of the HMS Dreadnought (1906) HMS Dreadnought, a revolutionary battleship that rendered all previous warships obsolete as "pre-dreadnoughts" upon its introduction. Ironically, this weakened Britain's power as a seafaring nation and sparked a major naval arms race in shipbuilding, as the new type of vessel opened up a brand-new chapter in naval warfare, annihilating the old ''status-quo''. The major participants in the race were Britain and Germany, tying in with the concept of new imperialism which gave way to the need for alliances. Overall, nations in the Triple Entente became fearful of the Triple Alliance (1882) Triple Alliance and ''vice versa''. Paul Kennedy is the historian who has most recently promulgated this thesis. Having a grand navy was a goal of Britain and Germany, in accord with American Alfred Thayer Mahan Alfred T. Mahan's influential thesis that control of the oceans was vital to a great nation, which seemed to explain Britain's success as a global power. Germany's decision to increase its naval might was the prime example of this, channeling latent industrial potential into increasing relative power, thereby indirectly challenging Britain's hegemony at sea. The prestige of attaining to or preserving world power through the navy was an important consideration for politicians and it also had domestic implications, serving as a national icon of attained "weltmacht" or world power status which in turn kept German industry churning, unemployment down and minimized internal strife through the focus on a common goal. This led to military rivalry with Britain, which in turn increased its own naval might and became less and less favorable toward Germany.

=Plans, Distrust and Mobilization: The ''First out the Gate'' Theory
= Closely related is the thesis adopted by many political scientists that the war plans of each power automatically escalated the conflict until it was out of control. Fritz Fischer and his followers have emphasized the inherently aggressive nature of Germany's Schlieffen Plan, which outlined how Germany would defend itself in the event of a two front war. If Germany was at war with both France and Russia, it must quickly eliminate one or the other from combat in order to stand a chance at winning the war. Time was of the essence. Due to French fortifications along the border with Germany, the plan called for a violation of Belgium's, and possibly the Netherlands' neutrality. In a greater context, France's own Plan XVII called for an offensive thrust into the industrial Ruhr Valley that would cripple the German ability to wage war. Russia's revised Plan XIX implied the mobilization of armies against both Austria-Hungary and Germany. All three created an atmosphere where generals and planning staffs of all the belligerent nations were anxious to capitalize on early offensive maneuvers to seize decisive victories. These military general staffs had elaborate mobilization plans with precise timetables, none more so than Germany, for whom it was decisive to consolidate victory against France before facing the slower-mobilizing Russia. Once the mobilization orders were issued it was understood by both generals and statesman alike that there was little or no possibility of turning back. Furthermore, the problem of communications in 1914 should not be underestimated; all nations still used telegraphy and ambassadors as the main form of communication, resulting in delays from hours to even days.

=Militarism and Authoritarianism
= President of the United States Woodrow Wilson and many Americans blamed the war on militarism, and this was a theme that figured prominently in anti-German propaganda throughout France, Great Britain and, from 1915 onwards, in the United States. The idea was that the Kaiser Wilhelm II and his autocratic Prussian government had a thirst for military power and glory, and such goals took priority over the needs and wishes of the people. The implication was that a "democratic" government would not have instigated the war, as it was widely proposed that Germany was ultimately responsible. True peace required the abdication of such rulers, the end of the aristocratic system, and consequently, the end of militarism. Wilson fought a "war to end all wars", explaining, "I cannot consent to take part in the negotiation of a peace which does not include freedom of the seas because we are pledged to fight not only to do away with Prussian militarism but with militarism everywhere. Neither could I participate in a settlement which did not include a league of nations because peace would be without any guarantee except universal armament which would be intolerable."{{fn|1}} Wilson also acknowledged what he called British and French militarism, hoping his plans for the League of Nations would be able to secure a permanent peace.

=Economic imperialism
= Lenin famously asserted that the worldwide system of imperialism was responsible for the war. In this he drew upon the economic theories of English economist John A. Hobson who had earlier predicted the outcome of economic imperialism, or unlimited competition for expanding markets, would lead to a global military conflict in his 1902 book entitled 'Imperialism'[http://www.fordham.edu/halsall/mod/1902hobson.html]. This argument proved persuasive to leftists in the immediate wake of the war and helped explain the popularity of Marxism and Communism among those who suffered most in the conflict. Lenin's 1917 pamphlet "Imperialism: The Highest Stage of Capitalism" [http://www.marxists.org/archive/lenin/works/1916/imp-hsc/] made the argument, specifically, that large banking interests in the various capitalist-imperialist powers had pulled the strings in the various governments and led them into the war. Related to the idea of economic "shadow forces" working behind the scenes to escalate the conflict, was a thesis, particularly popular in the U.S., that various arms dealers and military industries had led the Great Powers into the war, this is the so-called "Merchants of Death" thesis. However, in the context of the period, it is unclear how these industries had a direct and specific influence on policy-making, and how this sector of the economy was more influential than other industrial and trade sectors, which would presumably be damaged through disrupted trade flows and the loss of markets by a large-scale global war.

=Nationalism, Romanticism, Dawn of the "New Era"
= The civilian leaders of the European powers found themselves facing a wave of nationalism nationalist zeal that had been building across Europe for years, as memories of war faded or were convoluted into a romanticism romantic fantasy that resonated in the public conscience. Frantic diplomatic efforts to mediate the Austrian-Serbian quarrel simply became irrelevant, as public opinion (and elite opinion) in key countries demanded war to uphold national honor. Almost all the belligerents envisioned there would be glorious consequences to follow the war. The patriotic enthusiasm, unity and ultimate euphoria that took hold during the ''Spirit of 1914'' was full of that very optimism regarding the post-war future and left a distinct mark on a young Adolf Hitler. Also, the Socialist-Democratic movement had begun to exert pressure on aristocrats throughout Europe, who optimistically hoped a victory would reunite the country.

=A Culmination of European History
= A localized war between Austria-Hungary and Serbia was almost a given due to Austro-Hungarian Empire's deteriorating world position and the Pan-Slavic, separationist movement in the Balkans, which garnered the support of Slavic elements in Russia, primarily due to Russia's own wishes for a Kalingrad warm water port. Imperial Russia's expansion eastwards is a historical theme that deserves attention - a "threat" only reinforced by the experiences of the Germans in the Napoleonic Wars and Thirty Year's War - where their precarious position in the center of Europe led to the decision for an active defense such as the Schlieffen Plan. France's fury over "losing" the Alsace and Lorraine territories in the Franco-Prussian War gave way to a new word, revanchism, and Germany failed to isolate the French after the League of the Three Emperors fell apart. Overall, the "problems" of 1914 relate directly to problems that are a culmination of historical developments in Europe.

July Crisis and the Declarations of War
After the assassination of the Archduke Ferdinand on June 28, Austria-Hungary had waited for 3 weeks before deciding on a course of action. This wait was due to a large part of the army being on leave to help in gathering the harvest, which practically denied Austria the possibility of military action at the time. On July 23, assured by unconditional ('carte blanche') support of the Germans if war breaks out, it sent an July Ultimatum ultimatum to Serbia containing many demands, among them that Austrian agents would be allowed to take part in the investigation, and in general holding Serbia responsible for the assassination. The Serbian Government accepted all the terms, except that of the participation of the Austrian agents in the inquiry, which it saw as a violation of its sovereignty. Austria-Hungary, on its part, rejected the Serbian reply on July 26, broke diplomatic relations, and declared war on Serbia on July 28, proceeding to bombard Belgrade on July 29. On July 30 Austria-Hungary and Russia both ordered general mobilization of their armies. The Germans, having pledged their support to Austria-Hungary, sent Russia an ultimatum to stop mobilisation within 12 hours on July 31. On August 1, with the ultimatum expired, the German ambassador to Russia formally declared war. On August 2 Germany occupied Luxembourg, as a preliminary step to the invasion of Belgium and the Schlieffen Plan (ie. Germany had planned to attack France first according to the plan, and then Russia, which had already gone wrong) the same day yet another ultimatum was delivered to Belgium, requesting free passage for the German army on the way to France. The Belgians refused. On August 3 Germany declared war on France, and on August 4 invaded Belgium. This act, violating Belgian neutrality to which Prussia, France, and Britain were all committed to guarantee, gave Britain a reason, which up to that point had committed to side itself with either side, to declare war on Germany on August 4.

Opening hostilities
Some of the first hostilities of the war occurred in Africa and in the Pacific Ocean, in the colonies and territories of the European powers. On August 1914 a combined French and British Empire force invaded the German protectorate of Togoland in West Africa. Shortly thereafter, on August 10, German forces based in Namibia South-West Africa attacked South Africa, part of the British Empire. Another British Dominion, New Zealand, occupied Western Samoa German Samoa (later Western Samoa) on 30 August; on September 11 the Australian Naval and Military Expeditionary Force landed on the island of New Britain Neu Pommern (later New Britain), which formed part of German New Guinea. Within a few months, the Entente forces had driven out or had accepted the surrender of all German forces in the Pacific. Sporadic and fierce fighting, however, continued in Africa for the remainder of the war.

The borders shown here are the situation in 1911. In Europe, the Central Powers — the German Empire and the Austro-Hungarian Empire - suffered from mutual miscommunication and lack of intelligence regarding the intentions of each other's army. Germany had originally guaranteed to support Austria-Hungary's invasion of Serbia, but practical interpretation of this idea differed. Austro-Hungarian leaders believed Germany would cover her northern flank against Russia. Germany, however, had planned for Austria-Hungary to focus the majority of its troops on Russia while Germany dealt with France on the Western Front. This confusion forced the Austro-Hungarian army to split its troop concentrations from the south in order to meet the Russians in the north. The Serbian army, coming up from the south of the country, met the Austrian army at the Battle of Cer on 12 August.

A complete set of these images can be found at [http://www.worldwaronecolorphotos.com World War One Color Photos]. The Serbians occupied defensive positions against the Austrians. The first attack came on August 16, between parts of the 21st Austro–Hungarian division and parts of the Serbian Combined division. In harsh night-time fighting, the battle ebbed and flowed, until Stepa Stepanovic rallied the Serbian line. Three days later the Austrians retreated across the Danube, having suffered 21,000 casualties as against 16,000 Serbian. This marked the first major Allied victory of the war. The Austrians had not achieved their main goal of eliminating Serbia, and it became increasingly likely that Germany would have to maintain forces on two fronts. The Schlieffen Plan to deal with the Franco-Russian alliance involved delivering a knock-out blow to the French and then turning to deal with the more slowly mobilized Russian army. Rather than invading eastern France directly, German planners deemed it prudent to attack France from the north. To do so, the German army had to march through Belgium. Germany demanded free passage from the Belgian government, promising to treat Belgium as Germany's firm ally if permission was granted. The Belgian government's refusal to come to terms at zero-hour was an unpleasant surprise but the German army chose to follow through with its plan just the same. After entering Belgium territory, it soon encountered resistance at a fortified Liège (city) Liège. Although the army as a whole continued to make rapid progress into France, it was Britain's decision to declare war on Germany and honor a dated protection pact with Belgium that left the German government in disbelief and seriously hindered the military's plans. Britain sent an army to France (the British Expeditionary Force, or BEF) which advanced into Belgium and slowed the Germans. The first British soldier killed in the war was John Parr (soldier) John Parr, on 21 August 1914, near Mons. Initially the Germans had great successes in the Battle of the Frontiers (14–24 August 1914). However, Russia attacked in East Prussia, diverting German forces intended for the Western Front (WWI) Western Front. Germany defeated Russia in a series of battles collectively known as the Second Battle of Tannenberg (1914) Battle of Tannenberg (17 August – 2 September). This diversion exacerbated problems of insufficient speed of advance from railheads, not allowed for by the German General Staff, allowed French and British forces to finally halt the German advance on Paris at the First Battle of the Marne (September 1914) and the Entente forced the Central Powers into fighting a war on two fronts. The German army had fought its way into a good defensive position inside France and had permanently incapacitated 230,000 more French and British troops than it had lost itself in the months of August and September. Yet staff incompetence and leadership timidity, as Moltke the Younger had needlessly transferred troops from the right to protect Sedan, France Sedan, cost Germany the chance for an early knockout with its overly-ambitious plan.

Early stages: from romanticism to the Western Front trenches


Hopes and fears

In 1914, the perception of war was romanticism romanticized by many people, and its declaration was met with great unexpected enthusiasm, in a period known as the "August Madness." The common view on both sides was that it would be a short war of maneuver (typically estimated at the length of three months, sixth months for pessimists), with a few sharp actions (to "teach the enemy a lesson") and would end with a victorious entry into the enemy capital, then home for a victory parade or two and back to "normal" life. Many thought it would have finished by Christmas of that year. Few government officials however regarded the upcoming war with great pessimism and worry. Some military figures, such as Horatio Kitchener Lord Kitchener and Erich Ludendorff had predicted modern, industrialized warfare to be a lengthy excursion but were often simply ignored and thought crazy. Some political leaders, such as Theobald von Bethmann-Hollweg Bethmann Hollweg in Germany, were concerned by the potential social consequences of a war. International bond and financial markets entered severe crises in late July and early August reflecting worry about the financial consequences of war. The perceived excitement of war captured the imagination of many in the warring nations. Spurred on by propaganda and nationalist fervor, many eagerly joined the ranks in search of adventure. Few were prepared for what they actually encountered at the front. {{seealso|Recruitment to the British Army during WW I}}

Trench warfare begins
{{main|Western Front (World War I)}} Advances in military technology meant that defensive firepower out-weighed offensive capabilities, making the war particularly murderous, as tactics had failed to keep up. Barbed wire was a significant hindrance to massed infantry advances; artillery, now vastly more lethal than in the 1870s, coupled with machine guns, made crossing open ground a nightmarish prospect. German's began using Poison gas in World War I poison gas in 1915, and soon, both sides were using gas. Neither side ever won a battle with gas, but it made life even more miserable in the trenches and became one of the most feared, and longest remembered, horrors of the war. After the First Battle of the Marne, both Entente and German forces began a series of outflanking manoeuvres to try to force the other to retreat, in the so-called Race to the Sea. Britain and France soon found themselves facing entrenched German positions from Lorraine (province) Lorraine to Belgium's Flanders Flemish coast. Britain and France sought to take the offensive, while Germany defended occupied territories. One consequence was that German trenches were much better constructed than those of their enemy: Anglo-French trenches were only intended to be 'temporary' before their forces broke through German defences. Some hoped to break the stalemate by utilizing science and technology. In April 1915, the Germans used chlorine gas for the first time, opening a four mile wide hole in the Allied lines when French colonial troops retreated before it. This breach was closed by Canada Canadian soldiers at both the Second Battle of Ypres and Third Battle of Ypres, (where over 5000 Canada Canadian soldiers were gassed to death), earning German respect. Neither side proved able to deliver a decisive blow for the next four years, though protracted German action at Battle of Verdun Verdun throughout 1916, and the Entente's failure at the Battle of the Somme Somme, in the summer of 1916, brought the exhausted French army to the brink of collapse. Futile attempts at frontal assault - with a rigid adherence to unimaginative manuevere - came at a high price for both the British and the French poilu (infantry) and led to widespread mutinies especially during the time of the Nivelle Offensive in the spring of 1917. News of the Russian Revolution of 1917 Russian Revolution gave a new incentive to socialist sentiments among the troops, with its seemingly inherent promise of peace. Red flags were hoisted and the Internationale was sung on several occasions. At the height of the mutiny, 30,000 to 40,000 French soldiers participated. Image:Vimy tank.jpg Canadian.html"_title="Meaning of |left|thumb|200px|[[Canadian_troops advancing behind a tank at the Battle of Vimy Ridge, one of Canada's greatest military victories..html" title="Meaning of left|thumb|200px|[[Canadian">|left|thumb|200px|[[Canadian troops advancing behind a tank at the Battle of Vimy Ridge, one of Canada's greatest military victories.">left|thumb|200px|[[Canadian">|left|thumb|200px|[[Canadian troops advancing behind a tank at the Battle of Vimy Ridge, one of Canada's greatest military victories. Throughout 1915-17, the British Empire and France suffered far more casualties than Germany. However, while the Germans only mounted a single main offensive at Verdun, each failed attempt by the Entente to break through German lines was met with an equally fierce German counteroffensive to recapture lost positions. Around 800,000 soldiers from the British Empire were on the Western Front at any one time. 1,000 battalions, each occupying a sector of the line from the North Sea to the Orne River (Lorraine) Orne River, operated on a month-long four-stage rotation system, unless an offensive was underway. The front contained over 6,000 miles of trenches. Each battalion held its sector for around a week before moving back to support lines and then further back to the reserve lines before a week out-of-line, often in the Poperinge or Amiens areas. In the British-led Battle of Arras (1917) Battle of Arras during the 1917 campaign, the only military success was the capture of Vimy Ridge by the Canadian Corps under Sir Arthur Currie. It provided the allies with great military advantage and greatly contributed to the identity of Canada. See the Battle of Vimy Ridge for more information. {{-}}

Southern theatres


Ottoman Empire
{{main|Middle Eastern theatre of World War I}} The Ottoman Empire joined the Central Powers in October–November 1914, due to the secret Turko-German Alliance signed in August 1914. It threatened Russia's Caucasus Caucasian territories and Britain's communications with India and the East via the Suez canal. The British Empire opened another front in the South with the Gallipoli Campaign Gallipoli (1915) and Mesopotamian Campaign Mesopotamian campaigns. In Gallipoli, the Turkey Turks were successful in repelling the ANZACs (Australian and New Zealand Army Corps), forcing their eventual withdrawal and evacuation. In Mesopotamia, by contrast, after the disastrous Siege of Kut (1915–16), British Empire forces reorganised and captured Baghdad in March 1917. Further to the west in the Sinai and Palestine Campaign, initial British failures were overcome with Jerusalem being captured in December 1917 and the Egyptian Expeditionary Force,under Field Marshall Edmund Allenby, going on to break the Ottoman forces at the Battle of Megiddo (1918) Battle of Megiddo in September 1918. Russian armies generally had the best of it in the Caucasus. ''Vice-Generalissimo'' Enver Pasha, supreme commander of the Turkish armed forces, was a very Ambition ambitious man, with a dream to conquer Central Asia central Asia. He was not, however, a practical soldier. He launched an offensive with 100,000 troops against the Russians in the Caucasus in December of 1914. Insisting on a frontal attack against Russian positions in the mountains in the heart of winter, Enver lost 86% of his force at the Battle of Sarikamis. In 1917, Russian Grand Duke Nicholas assumed senior control over the Caucasus front. Nicholas tried to have a railway built from Georgia (country) Russian Georgia to the conquered territories with a view to bringing up more supplies for a new offensive in 1917. But, in March of 1917 (February in the pre-revolutionary Russian calendar), the Czar was overthrown in the February Revolution and the Russian army began to slowly fall apart.

Italian participation
{{main|Italian Campaign (World War I)}} Italy had been allied to the German and Austro-Hungarian Empires since 1882, but had its own designs against Austrian territory in the Trentino, Istria and Dalmatia, and maintained a secret 1902 understanding with France, effectively nullifying its alliance commitments. Italy refused to join Germany and Austria-Hungary at the beginning of the war, because their alliance was defensive, while Austria had declared war on Serbia. The Austrian government started negotiations to obtain Italian neutrality in exchange for French territories (Tunisia), but Italy joined the Triple Entente Entente by signing the London Pact in April and declaring war on Austria-Hungary in May 1915; it declared war against Germany fifteen months later. In general, the Italians enjoyed numerical superiority, but were poorly equipped. The Italians went on the offense to achieve their territorial goals. In the Trentino-South Tyrol Trentino front, the Austro-Hungarian defence took advantage of the elevation of their bases in the mostly mountainous terrain, which was anything but suitable for military offensives. After an initial Austro-Hungaric strategic retreat to better positions, the front remained mostly unchanged, while Austrian Kaiserschützen and Standschützen and Italian Alpini Corps Alpini fought bitter close combat battles during summer and tried to survive during winter in the high mountains. The Austro-Hungarians counter-attacked in the Asiago Altopiano of Asiago towards Verona and Padua in the spring of 1916 (''Strafexpedition''), but they also made little progress. Beginning in 1915, the Italians mounted 11 major offensives on the other front, the SoÄ?a River Isonzo front (the part of the border north of Trieste), all repelled by the Austro-Hungarians, who had the higher ground. In the summer of 1916, the Italians captured the town of Gorizia. After this minor victory, the front remained practically stable for over one year, despite several Italian offensives, again all on the Isonzo front. In the fall of 1917, thanks to the improving situation on the Eastern front, the Austrians received large reinforcements, including German assault troops. On October 26, they launched a crushing offensive that resulted in the victory of Battle of Caporetto Caporetto: the Italian army was routed, but after retreating more than 100km, it was able to reorganise and hold at the Battle of the Piave River. In 1918, the Austrians repeatedly failed to break the Italian line, and, decisively defeated in the Battle of Vittorio Veneto, surrendered to the Entente powers in November. Throughout the war, Austro-Hungarian Chief of Staff, Conrad von Hötzendorf had a deep hatred for the Italians because he had always perceived them to be the greatest threat to his state. Their betrayal in 1915 enraged him even further. His hatred for Italy blinded him in many ways, and he made many foolish tactical and strategic errors during the campaigns in Italy.

The War in the Balkans
After repelling three Austrian invasions during August-December 1914, Serbia fell to combined invasion by Germany, the Austro-Hungarian Empire and the Kingdom of Bulgaria, (the latter of which joined the Central Powers in September, 1915) in October 1915. The Serbian army was defeated at Gjilan Kosovo (near the ancient mining city of Novo Brdo), then retreated into Albania and Greece. In late 1915, a Franco-British force landed at Salonica in Greece to offer assistance and to pressure the Greek government into war against the Central Powers. Unfortunately for the Allies, the pro-allied Greek government of Eleftherios Venizelos was dismissed, by the pro-German Constantine I of Greece King Constantine I, before the allied expeditionary force had even arrived. The King then further prevented official Greek entry into the war for two years, until 1917. Meanwhile, the Salonica Front proved entirely immobile, so much so that it was joked that Salonica was the largest German prisoner of war camp. Only at the very end of the war, after most of the German and Austro-Hungarian troops had been removed, leaving the Front held by the Bulgarians alone, were the Entente powers able to make a breakthrough. This led to Bulgaria's signing an armistice on September 29, 1918.

Picture taken in February 1915, just before the German winter-offensive started in heavy snowstorms. {{main|Eastern Front (World War I)}} While the Western Front had reached stalemate in the trenches, the war continued in the east. The Russian initial plans for war had called for simultaneous invasions of Austrian Galicia (Central Europe) Galicia and German East Prussia. Although Russia's initial advance into Galicia was largely successful, they were driven back from East Prussia by the victories of the German generals Paul von Hindenburg Hindenburg and Erich Ludendorff Ludendorff at Battle of Tannenberg (1914) Tannenberg and the Battle of the Masurian Lakes Masurian Lakes in August and September 1914. Russia's less-developed industrial base and ineffective military leadership was instrumental in the events that unfolded. By the spring of 1915, the Russians were driven back in Galicia, and, in May, the Central Powers achieved a remarkable breakthrough on Poland's southern fringes, capturing Warsaw on August 5 and forcing the Russians to withdraw from all of Poland, an action known as the "Great Retreat" by the Russian Empire and the "Great Advance" by Germany.

The Russian Revolution
{{main|Russian Revolution of 1917}} Dissatisfaction with the Russian government's conduct of the war grew despite the success of the June 1916 Brusilov offensive in eastern Galicia (Central Europe) Galicia against the Austrians, when Russian success was undermined by the reluctance of other generals to commit their forces in support of the victorious sector commander. Allied and Russian fortunes revived only temporarily with Romania's entry into the war on August 27: German forces came to the aid of embattled Austrian units in Transylvania, and Bucharest fell to the Central Powers on December 6. Meanwhile, internal unrest grew in Russia, as the Nicholas II of Russia Tsar remained out of touch at the front, while Alexandra of Hesse Empress Alexandra's increasingly incompetent rule drew protests from all segments of Russian political life, resulting in the murder of Alexandra's favorite Grigori Rasputin Rasputin by conservative noblemen at the end of 1916.

In March 1917, demonstrations in Saint Petersburg, Russia St. Petersburg culminated in the abdication of Nicholas II of Russia Tsar Nicholas II and the appointment of a weak Russian Provisional Government, 1917 Provisional Government, which shared power with the socialists of the Petrograd Soviet. This division of power led to confusion and chaos, both on the front and at home, and the army became increasingly ineffective. The war, and the government, became more and more unpopular, and the discontent led to a rise in popularity of the Bolshevik political party party, led by Vladimir Lenin, who were able to gain power. The October Revolution triumph of the Bolsheviks in November was followed in December by an armistice and negotiations with Germany. At first, the Bolsheviks refused to agree to the harsh German terms, but when Germany resumed the war and marched with impunity across Ukraine, the new government acceded to the Treaty of Brest-Litovsk on March 3, 1918, which took Russia out of the war and ceded vast territories, including Finland, the Baltic states Baltic provinces, Poland and Ukraine to the Central Powers. After the Russians dropped out of the war, the Entente no longer existed. The Allied powers led a small-scale invasion of Russia. The invasion was made with intent primarily to stop Germany from exploiting Russian resources and, to a lesser extent, to support the Whites in the Russian Revolution. Troops landed in Arkhangelsk Archangel (see North Russia Campaign) and in Vladivostok.

Events of 1917 would prove decisive in ending the war, although their effects would not be fully felt until 1918. The British naval blockade of Germany began to have a serious impact on morale and productivity on the German home-front. In response, in February 1917, the German General Staff (Oberste Heeresleitung OHL) were able to convince Chancellor Theobald von Bethmann-Hollweg to declare unrestricted submarine warfare, with the goal of starving Britain out of the war. Tonnage sunk rose above 500,000 tons per month from February until July, peaking at 860,000 tons in April. After July, the reintroduced convoy system was extremely effective in neutralizing the U-boat threat, thanks to American experimentation. Britain was safe from the threat of starvation and the German war industry remained deprived materially. The decisive victory of Germany at the Battle of Caporetto led to the Allied decision at the Rapallo Conference to form the Supreme Allied Council at Versailles to co-ordinate plans and action. Previously British and French armies had operated under separate command systems. In December, the Central Powers signed an Armistice with Russia, thereby releasing troops from the eastern front for use in the west. Ironically, German troop transfers could have been greater if their territorial acquisitions had not been so dramatic. With both German reinforcements and new United States American troops pouring into the Western Front, the final outcome of the war was to be decided in that front. The Central Powers knew that they could not win a protracted war now that American forces were certain to be arriving in increasing numbers, but held high hopes for a rapid offensive in the West, using their reinforced troops and new infantry tactics. Furthermore, the rulers of both the Central Powers and the Allies became more fearful of the threat first raised by Ivan Bloch in 1899, that protracted industrialized war threatened social collapse and revolution throughout Europe. Both sides urgently sought a decisive, rapid victory on the Western Front as they were both fearful of collapse or stalemate.

Entry of the United States

America's policy of insisting on neutral rights while also trying to broker a peace resulted in tensions with both Berlin and London. US president Woodrow Wilson repeatedly warned that he would not tolerate unrestricted submarine warfare, and the Germans repeatedly promised to stop. In January 1917 the German military decided that unrestricted submarine warfare was the best gamble to choke British supplies before the American troops could arrive in large numbers. A proposal to Mexico to join the war was exposed in February, bringing war closer. (See Zimmermann telegram). After further U-boat attacks on American merchant ships, Wilson requested that Congress declare war on Germany, which it did on April 6, 1917 (see: ''wikisource:Woodrow Wilson declares war on Germany Woodrow Wilson declares war on Germany'' on Wikisource). The House of Representatives approved the war resolution 373-50, the Senate 82-6, with opposition coming mostly from German American districts. Wilson hoped war could be avoided with Austria-Hungary; however, when it kept its loyalty to Germany, the US declared war on Austria-Hungary in December 1917. Although the American contribution to the war was important, particularly in terms of the threat posed by an increasing US infantry presence in Europe, the United States was never formally a member of the Allies, but an "Associated Power." Significant numbers of fresh American troops only arrived in Europe in the summer of 1918, when they started arriving at 10,000 a day. Germany miscalculated that it would be many more months before large numbers of American troops could be sent to Europe, and that, in any event, the U-boat offensive would prevent their arrival. The United States Navy sent a battleship group to Scapa Flow to join with the British Grand Fleet, a number of destroyers to Cobh Queenstown, Ireland and several submarines to the Azores and to Bantry Bay, Ireland to help guard convoys. Several regiments of U.S. Marines were also dispatched to France. However, it would be some time before the United States would be able to contribute significant manpower to the Western and Italian fronts. The British and French wanted the United States to send its infantry to reinforce their troops already on the battlelines, and not use scarce shipping to bring over supplies. Thus the Americans primarily used British and French artillery, airplanes and tanks. However, General John J. Pershing, American Expeditionary Force (AEF) commander, refused to break up American units to be used as reinforcements for British Empire and French units (though he did allow African American combat units to be used by the French). Pershing ordered the use of frontal assaults, which had been discarded by that time by British Empire and French commanders as too costly in lives of their troops. To the astonishment of the Allies, the dispirited Germans broke and ran when the Americans came running, and the AEF suffered the lowest casualty rate of any army on the Western Front, with most recorded deaths being attributed to disease.

German Spring Offensive of 1918

This Spring Offensive sought to divide the British Empire and French armies in a series of feints and advances. The German leadership hoped to strike a decisive blow against the enemy before significant United States forces could be deployed. Before the offensive even began, Ludendorff made what may have been a fatal mistake by leaving the elite German Eighth Army Eighth Army in Russia and sending over only a small portion of the German forces from the east to aid the offensive in the west. Operation Michael opened on 21 March, 1918, with an attack against British Empire forces, towards the rail junction at Amiens. It was Ludendorff's intention to split the British Empire and French armies at this point. German forces achieved an unprecedented advance of 60 km. For the first time since 1914, maneuver had returned to the battlefield. British and French trenches were defeated using novel infiltration tactics. Up to this time, attacks had been characterized by long artillery bombardments and continuous-front mass assaults. However, in the Spring Offensive, the German Army used artillery briefly and infiltrated small groups of infantry at weak points, attacking command and logistics areas and surrounding points of serious resistance. These isolated positions were then destroyed by more heavily armed infantry. German success relied greatly on this tactic. The front line had now moved to within 120 kilometers of Paris. Three super-heavy Krupp railway guns advanced and fired 183 shells on Paris, causing many Parisians to flee the city. The initial stages of the offensive were so successful that German Wilhelm II of Germany Kaiser Wilhelm II declared March 24 a national holiday. Many Germans thought victory to be close; however, after heavy fighting, the German offensive was halted. The Germans had a brilliant new stormtrooper, or Hutier tactics that avoided the trenches and sent small units on preplanned raids deep behind the lines to control and communication centers. That worked very well but the Germans, lacking tanks or motorized artillery, were unable to consolidate their positions. The British and French learned that they had to fall back a few miles and the Germans would be disorganized and vulnerable to counterattack. American divisions, which Pershing had sought to field as an independent force, were assigned to the depleted French and British Empire commands on 28 March. A supreme command of Allied forces was created at the Doullens Conference, in which British Field Marshal Douglas Haig handed control of his forces over to Ferdinand Foch. Following Operation Michael, Germany launched Operation Georgette to the north against the English channel Channel ports. This was halted, by the Allies, with less significant territorial gains to Germany. Third Battle of the Aisne Operations Blücher and Yorck were then conducted by the German Army to the south, broadly towards Paris. Next, Operation Marne was launched on 15 July as an attempt to encircle Reims, beginning the Second Battle of the Marne. The resulting Allied counterattack marked their first successful offensive of the war. By July 20, the Germans were back at their Kaiserschlacht starting lines, having achieved nothing. Following this last phase of the ground war in the West, the German Army never again held the initiative. German casualties between March and April 1918 were 270,000, including many of the highly trained stormtroopers. Their best soldiers were gone, just as the Americans started arriving. Meanwhile, Germany was crumbling internally as well. Anti-war marches were a frequent occurrence and morale within the army was at low levels. Industrial output had fallen 53% from 1913.

Allied victory: summer and fall 1918

The Battle of Amiens developed with III Corps British Fourth Army Fourth British Army on the left, the French First Army First French Army on the right, and the Canadian Corps Canadian and Australian Corps spearheading the offensive in the centre. It involved 414 tanks of the Mark I (tank) Mark IV and Mark V (tank)#Mark V Series Mark V type, and 120,000 men. They advanced as far as twelve kilometres into German-held territory in just seven hours. Erich Ludendorff referred to this day as "the Black Day of the German army". However, after a few days, the offensive had slowed down— British Empire units had encountered problems with all but seven tanks. On 15 August, General Haig called a halt and began planning a new offensive in Albert, Somme Albert. This Second Battle of the Somme (1918) Second Battle of the Somme began on August 21. Some 130,000 United States troops were involved, along with soldiers from British Third Army Third and British Fourth Army Fourth British Armies. It was an overwhelming success for the Allies. The German Second Army Second German Army was pushed back over a 55km front. The town of Bapaume was captured on August 29 and by September 2, the Germans were on the Hindenburg Line, the starting point of the War. The Allied attempt to take the Hindenburg Line (the Meuse-Argonne Offensive) began September 26, as 260,000 American soldiers went "over the top". All divisions were successful in capturing their initial objectives, except the U.S. 79th Infantry Division, which met stiff resistance at Montfaucon and took an extra day to capture the objective. By the start of October, it was evident that Germany could no longer mount a successful defense, let alone a counterattack. Numerically on the frontline they were increasingly outnumbered, with the few new recruits too young or too old to help much. Rations were cut for men and horses because the food supply was critical. Ludendorff had decided, by October 1, that Germany had two ways out of the War—total annihilation or an armistice. He recommended the latter to senior German officials at a summit on that very same day. During October, Pershing's artillery continued to unrelentingly pound the exhausted and bewildered Germans, all along the Meuse-Argonne front. The Allied pressure did not let up until the end of the war. Meanwhile, news of Germany's impending military defeat had spread throughout the German Armed forces. The threat of general mutiny was rife. Naval commander Admiral Reinhard Scheer Scheer and Ludendorff decided to launch a last ditch attempt to restore the "valour" of the German Navy. Knowing any such action would be vetoed by the government of Prince Maximilian of Baden Max von Baden, Ludendorff decided not to inform him. Nonetheless, word of the impending assault reached sailors at Kiel. Many rebelled and were arrested, refusing to be part of a naval offensive which they believed to be nothing more than a suicide bid. It was Ludendorff who took the blame for this—the Kaiser dismissed him on 26 October. With power coming into the hands of new men in Berlin, further fighting became impossible. With 6 million German casualties (1.8 million dead), they moved toward peace. Prince Maximilian of Baden Prince Max von Baden took charge of the new German government. Negotiations for a peace began immediately upon his appointment. In the matter of the German monarchy, he was torn between the idea of a constitutional monarchy--in which he himself was in line for the crown-- or a republic. Wilson demanded the abdication of the Kaiser and there was no resistance when the Social Democratic social democrat Philipp Scheidemann on November 9 declared Germany to be a republic. Von Baden then announced that the Kaiser was to abdicate, along with all other princes in the Reich. Imperial Germany was dead; a new Germany had been born: the Weimar Republic.

End of the war

The collapse of the Central Powers came swiftly. Bulgaria was the first to sign an armistice (29 September 1918). The sailors of Germany's High Seas Fleet mutinied starting 29 October. On 30 October, the Ottoman Empire capitulated. On November 3, Austria-Hungary sent a flag of truce to the Italian Commander to ask terms. The Armistice with Austria was granted to take effect at three o'clock on the afternoon of November 4. Austria and Hungary signed separate armistices following the overthrow of the Habsburg monarchy and the collapse of the Austro-Hungarian Empire. Following the outbreak of the German Revolution, a republic was proclaimed on 9 November, marking the end of the monarchy. The Kaiser fled the next day to the neutral Netherlands, which granted him political asylum (see Weimar Republic for details). On 11 November, Armistice with Germany (Compiègne) an armistice with Germany was signed in a railroad carriage at Compiègne in France where Germans had previously dictated terms to France, ending the Franco-Prussian War in 1871. A final offensive was scheduled for November 11, and was launched at 10:30, a half-hour before the hostilities were to end. This thrust had the goal of re-capturing the city of Mons, one of the first French cities to fall to the initial German offensive. This last pointless offensive ironically cost 11,000 Allied lives. At 1100 hours that day ("eleventh hour of the eleventh day of the eleventh month"), a ceasefire came into effect and the opposing armies on the Western Front began to withdraw from their positions. Canadian George Lawrence Price is traditionally regarded as the last soldier killed in the Great War: he was shot by a German Sniper and died at 1058 hours. A formal state of war between the two sides persisted for another seven months until it was finally ended by the signing of the Treaty of Versailles on June 28, 1919 with Germany and the following treaties with Austria, Hungary, Bulgaria and The Ottoman Empire signed at Treaty of St. Germain St. Germain, Treaty of Trianon Trianon, Treaty of Neuilly Neuilly and Treaty of Sèvres Sèvres respectively. However, the latter treaty with the Ottoman Empire was followed by strife (the Turkish Independence War) and a final peace treaty was signed by the Allied Powers and the country that would shortly become the Republic of Turkey, at Treaty of Lausanne Lausanne on 24 July 1923. Many war memorials date the end of the war as being when the Versailles treaty was signed, 1919; by contrast, most commemorations of the war's end concentrate on the Armistice of 1918; however, the formal ending of all hostilities was not until 1923. {{further|World War I casualties}}

Economics and Manpower issues
Gross Domestic Product (GDP) increased for the main Allies (the UK, Italy, and U.S.), but decreased in France and Russia, in neutral Netherlands, and in the main three Central Powers. The shrinkage in GDP in Austria, Russia, France, and the Ottoman Empire reached 30 to 40 percent. In Austria, for example, most of the pigs were slaughtered and, at war's end, there was no meat. All nations had increases in the government's share of GDP, surpassing fifty percent in both Germany and France and nearly reaching fifty percent in the UK. To pay for purchases in the US, the UK cashed in its massive investments in American railroads, then began borrowing heavily on Wall Street. Wilson was on the verge of cutting off the loans in late 1916, but with war imminent with Germany, he allowed a massive increase in US government lending to the Allies. After 1919, the US demanded repayment of these loans, which, in part, were funded by German reparations, which, in turn, were supported by American loans to Germany. This circular system collapsed in 1931 and the loans were never repaid. One of the most dramatic effects was the expansion of governmental powers and responsibilities in Britain, France, the United States, and the Dominions of the British Empire. In order to harness all the power of their societies, new government ministries and powers were created. New taxes were levied, and laws enacted, all designed to bolster the war effort, many of which have lasted to this day. At the same time, the war strained the abilities of the formerly large and bureaucratized governments such as in Austria-Hungary and Germany. Here, however, the long term effects were clouded by the defeat of these governments. Families were altered by the departure of many men. With the death or absence of the primary wage earner, women were forced into the workforce in unprecedented numbers, at least in many of the Entente powers. At the same time, industry needed to replace the lost laborers sent to war. This aided the struggle for suffragette voting rights for women. As the war slowly turned into a war of attrition, conscription was implemented in some countries. This issue was particularly explosive in Canada, and opened a political gap between the French-Canadians, who claimed their true loyalty was to Canada and not the British Empire, and the English-speaking majority which saw the war as a duty to both Empire and Canada, and a way of demonstrating leadership and high-contribution to the British Empire. Prime Minister Sir Robert Borden pushed through a Military Service Act that caused the Conscription Crisis of 1917. In Britain rationing was finally imposed in early 1918 and was limited to meat, sugar and fats (butter and oleo)--but not bread; the new system worked smoothly. From 1914 to 1918 trade union membership doubled, from a little over four million to a little over eight million. Work stoppages and strikes became frequent in 1917-18 as the unions expressed grievances regarding prices, liquor control, pay disputes, "dilution," fatigue from overtime and from Sunday work, and inadequate housing. Conscription put into uniform nearly every physically fit man, six million out of ten million eligible in Britain. Of these about 750,000 lost their lives and 1,700,000 were wounded. Most deaths were to young unmarried men; however 160,000 wives lost husbands and 300,000 children lost fathers. [Havighurst p 134-5]

Technology
Image:Nieuport.jpg right|thumb|250px|Nieuport Fighter, France 1917. {{seealso|Technology during World War I}} The First World War was a clash of 20th century technology with 19th century tactics. This time, millions of soldiers, both volunteers and conscripts fought on all sides, with Kitchener's Army being a notable all volunteer force. Much of the war's combat involved trench warfare, where hundreds often died for each metre of land gained. Many of the deadliest battles in history occurred during the First World War. Such battles include Battle of Ypres Ypres, Vimy Ridge, Battle of the Marne Marne, Battle of Cambrai Cambrai, Battle of the Somme (1916) Somme, Battle of Verdun Verdun, and Battle of Gallipoli Gallipoli. Artillery was responsible for the largest number of casualties during the First World War. The war consumed vast quantities of explosives. During the war, the Haber process of nitrogen fixation was employed to provide the German forces with a continuing supply of powder for the ongoing conflict in the face of British naval control over the trade routes for naturally occurring nitrates. The First World War also saw the use of chemical warfare and aerial bombardment, both of which had been outlawed under the 1907 Hague Conventions (1899 and 1907) Hague Convention. Chemical warfare was Use of poison gas in World War I a major distinguishing factor of the war. Gases used ranged from tear gas to disabling chemicals such as mustard gas and killing biological agent agents like phosgene. Only a small proportion of total war casualties were caused by gas, but it achieved harassment and psychological effects. Effective countermeasures to gas were found in gas masks and hence in the later stages of the war, as the use of gas increased, in many cases its effectiveness was diminished. Fixed-wing aircraft were World War I Aviation first used militarily during the First World War. Initial uses consisted primarily of reconnaissance, though this developed into Close air support ground-attack and Fighter aircraft fighter duties as well. Strategic bombing aircraft were created principally by the Germans and British, though the former used Zeppelins to this end as well. U-boats (submarines) were used in combat shortly after the war began. Alternating between restricted and unrestricted submarine warfare during the First Battle of the Atlantic, they were employed by the Kaiserliche Marine in a strategy of defeating the British Empire through a tonnage war. The deaths of British merchantmen and the invulnerability of U-boats led to the development of several countermeasures: depth charges (1916), hydrophones (passive sonar, 1917), blimps, hunter-killer submarines (HMS ''R-1'', 1917), ahead-throwing weapons, & dipping hydrophones (both abandoned 1918). To extend their operations, the Germans proposed supply submarines (1916). Most of these would be forgotten in the interwar period until World War II revived the need. Tanks were introduced in World War I by the British and created mechanized warfare that dominated the rest of the 20th century. The Mark I (tank) first tank was nicknamed ''Mother''. The first use of tanks was during the Battle of the Somme on 15 September 1916. This was not as successful as intended, but as a start the tanks proved their value against the machine gun. Trenches, the machine gun, air reconnaissance, barbed wire, and modern artillery with shrapnel shell fragmentation shells helped stalemate the battle lines of World War I by making massed infantry attacks deadly for the attacker. The infantry was armed mostly with a bolt action magazine rifle, but the machine gun with the ability to fire hundreds of rounds per minute blunted infantry attacks as a offensive weapon; therefore, the British sought a solution and created the tank. Their first use proved tanks needed infantry support and massed formations, but within a year the British were fielding tanks by the hundreds and showed their potential during the Battle of Cambrai, in November 1917, breaking the Hindenburg Line while capturing 8000 enemy and 100 artillery guns. Dirigible balloons were used as stationary reconnaissance points on the front lines. Balloons commonly had a crew of two with parachutes: upon an enemy air attack on the flammable balloon the balloon crew would parachute out. Recognised for their value as observer platforms, they were important targets of enemy aircraft; fixed, they were also heavily defended by antiaircraft guns. Blimps and balloons helped contribute to the stalemate of the trench warfare of World War I, and the dirigible balloons contributed to air to air combat among the aircraft to defend the skies for air superiority due to its significant reconnaissance value. The Germans conducted air raids during 1915 and 1916 on England and London with dirigible balloons with the intent of damaging the morale and will to fight of the British and cause aircraft to be reassigned to England away from the front lines. Dirigible balloons were part of the new found aerial warfare of World War I.

Aftermath
{{main|Aftermath of World War I}} The First World War ended with a Europe scarred by trenches, spent resources, and littered with the bodies of the millions who died in battle. The direct consequences of World War I brought many old regimes crashing to the ground, and ultimately, would lead to the end of 300 years of European hegemony in the world. No other war had changed the map of Europe so dramatically--four empires were shattered: the German Empire German, the Austria-Hungary Austro-Hungarian, the Ottoman Empire Ottoman and the Imperial Russia Russian. Their four dynasties, the Hohenzollerns, the Habsburgs, the Ottoman Empire Ottomans, and the Romanovs, who had roots of power back to the days of the Crusades, all fell during or after the war. In Australian and New Zealand popular legend, the First World War is known as the nation's "baptism of fire", as it was the first major war which the newly established countries fought, and is one of the first cases where Australian troops fought as Australians, not just subjects of the British Empire. Anzac Day (Australia New Zealand Army Corps) is thus held in great reverence by many Australians and New Zealanders. Similarly, Anglo-Canadians believe that they proved they were their own country, not just subjects of the British Empire. Indeed, many Canadians refer to their country as a nation "forged from fire," as Canadians were respected internationally as an independent nation from the conflagrations of war and bravery. Like their British counterparts, Canadians commemorate the war dead on Remembrance Day.

Social trauma
The experiences of the war led to a sort of collective national trauma afterwards for all the participating countries. The optimism of 1900 was entirely gone and those who fought in the war became what is known as "the Lost Generation" because they never fully recovered from their experiences. For the next few years, much of Europe began its mourning, memorials were erected in thousands of villages and towns. This social trauma manifested itself in many different ways. Some people were revolted by nationalism and what it had caused and began to work toward a more internationalism (politics) internationalist world through organizations such as the League of Nations. Pacifism became increasingly popular. Others had the opposite reaction, feeling that only strength and militarism military might could be relied on for protection in a chaotic and inhumane world that did not respect hypothetical notions of civilization. Certainly a sense of disillusionment and cynicism became pronounced, with Nihilism growing in popularity. This disillusionment towards humanity found a cultural climax with the Dadaist artistic movement. Many people believed that the war heralded the end of the world as they had known it, including the collapse of capitalism and imperialism. Communist and socialist movements around the world drew strength from this theory, enjoying a level of popularity they had never known before. These feelings were most pronounced in areas directly or particularly harshly affected by the war, such as central Europe, Russia, Germany, and France.

Other names
World War I has also been called "The Great War" (a title previously used to refer to the Napoleonic Wars) or sometimes "the war to end all wars" until World War II. The term "First World War", implying an event distinct from a "Second World War" has fallen into disfavour by some scholars, who regard World War I as merely the first phase of a three-decade long war spanning the period 1914–1945.{{fn|2}}

''"The lamps are going out all over Europe; we shall not see them lit again in our lifetime."'' - Sir Edward Grey, British Foreign Secretary, at the beginning of the war. ''"Yesterday I visited the battlefield of last year. The place was scarcely recognisable. Instead of a wilderness of ground torn up by shell, the ground was a garden of wild flowers and tall grasses. Most remarkable of all was the appearance of many thousands of white butterflies which fluttered around. It was as if the souls of the dead soldiers had come to haunt the spot where so many fell. It was eerie to see them. And the silence! It was so still that I could almost hear the beat of the butterflies' wings".'' - a British officer, 1919. ''"The First World War killed fewer victims than the Second World War, destroyed fewer buildings, and uprooted millions instead of tens of millions - but in many ways it left even deeper scars both on the mind and on the map of Europe. The old world never recovered from the shock".'' - Edmond Taylor, in ''"The Fossil Monarchies"'' ''"Soldiers! Heroes! The supreme command has erased our regiment from its records. Our regiment has been sacrificed for the honor of Belgrade and the Fatherland. Therefore, you no longer have to worry for your lives - they do not exist anymore. So, forward to glory! For King and Homeland! Long live the king! Long live Belgrade!"'' — major Dragutin Gavrilovic, to defenders of Belgrade in First World War ''In Flanders fields the poppies blow
''Between the crosses, row on row,
''That mark our place; and in the sky
''The larks, still bravely singing, fly
''Scarce heard amid the guns below.''
- Canadian lieutenant colonel John McCrae, from the poem ''"In Flanders Fields"'' ''What passing-bells for these who die as cattle?
''Only the monstrous anger of the guns.''
- Wilfred Owen, from ''Anthem for Doomed Youth'' ''"Gott strafe England"'' was a common slogan of the German Army, which means ''"May God punish England"''. ''"In war-time the word patriotism means suppression of truth".'' - Siegfried Sassoon in 'Memoirs of an Infantry Officer'. ''"In war there are three courses of action open to the enemy, and he usually chooses the fourth".'' - General Helmuth von Moltke'. ''"We will support Britain to the last man and the last shilling".'' - Andrew Fisher, Australian Prime Minister at the outbreak of the war.
