World War I (WWI, WW1), also known as the First World War, Great War and War to End All Wars, was a global military conflict which involved the majority of the world's great powers,[2] organized into two opposing military alliances: the Entente Powers and the Central Powers.[3] Over 70 million military personnel were mobilized in one of the largest wars in history.[4] In a state of total war, the major combatants placed their scientific and industrial capabilities at the service of the war effort. Over 15 million people were killed, making it one of the deadliest conflicts in human history.[5]
The proximate cause for the war was the 28 June 1914 assassination of Archduke Franz Ferdinand of Austria, heir to the Austro-Hungarian throne, by a Bosnian-Serb nationalist, Gavrilo Princip. Austria-Hungary's resulting demands against the Kingdom of Serbia led to the activation of a series of alliances which within weeks saw all of the major European powers at war. As a consequence of the global empires of many European nations, the war soon spread worldwide.
By the war's end, four major imperial powers - Germany, Russia, Austria-Hungary, and the Ottoman Empire - had been militarily and politically defeated, with the latter two ceasing to exist as autonomous countries.[6] The revolutionized Soviet Union emerged from the Russian Empire, while the map of central Europe was completely redrawn into numerous smaller states.[7] The League of Nations was formed in the hope of preventing another such conflict. The European nationalism spawned by the war, the repercussions of Germany's defeat, and the Treaty of Versailles would eventually lead to the beginning of World War II in 1939.[8]

Background
In the 19th century, the major European powers had gone to great lengths to maintain a "balance of power" throughout Europe, resulting in a complex network of political and military alliances throughout the continent.[9] The first of these major alliances formed in 1879, when the German Empire and Austria-Hungary signed treaties creating the Dual Alliance, seen as a method of combating Russian influence in the Balkans as the Ottoman Empire continued to weaken.[9] In 1882, this alliance was expanded to include Italy in what became the Triple Alliance.[10] European conflict was averted largely due to a carefully planned network of treaties between the German Empire and the remainder of Europe—orchestrated by Chancellor Otto von Bismarck. Bismarck's system of alliances was gradually deconstructed following the coronation of Kaiser Wilhelm II, with treaties[which?] between Germany and Russia ending in 1890. Two years later the Franco-Russian Alliance was signed to counteract the force of the Triple Alliance. In 1907, the British Empire joined France and Russia, signalling the beginning of the Triple Entente.[9]
As German industrial power grew, Kaiser Wilhelm II devoted significant economic resources to the establishment of the Kaiserliche Marine, in order to be capable of rivaling the Royal Navy.[11] As a result, both nations strove to outbuild each other in terms of capital ships. With the launch of HMS Dreadnought in 1906, the British Empire gained a significant advantage over their German rivals.[11] The arms race between Britain and Germany eventually extended to the rest of Europe, with all the major powers devoting their industrial base to the production of the equipment and weapons necessary for a pan-European conflict.[12] Between 1908 and 1913, the military spending of the European powers increased by 50%.[13]
In 1909, Austria-Hungary annexed Bosnia-Herzegovina from the Ottoman Empire, greatly angering the Russian Romanov Dynasty and the Kingdom of Serbia, as Bosnia-Herzegovina contained a significant Slavic Serbian population.[14] Russian political maneuvering in the region destabilized peace accords that were already fracturing in what was known as "the Powder keg of Europe".[14] In 1913, the First Balkan War was fought between the Balkan League and the fracturing Ottoman Empire. The resulting Treaty of London further shrank the Ottoman Empire, creating an independent Albanian State while enlarging the territorial holdings of Bulgaria, Serbia and Greece. When Bulgaria attacked both Serbia and Romania on 13 June 1913 it lost all of Macedonia to Serbia and Southern Dobruja to Romania in the 33–day Second Balkan War, further destabilizing the region.[15]
On 28 June 1914, Gavrilo Princip, a Bosnian-Serb student and member of Young Bosnia, assassinated Archduke Franz Ferdinand of Austria in Sarajevo.[16] Suspecting Serbian involvement in the assassination,[16] Austria-Hungary delivered the July Ultimatum to Serbia, a series of ten demands aimed at diplomatically undermining Serbia.[17] When Serbia acceded to eight of the ten demands levied against it in the ultimatum, Austria-Hungary declared war on Serbia on 28 July 1914. The Russian Empire, unwilling to allow Austria-Hungary to eliminate its influence in the Balkans, ordered a partial mobilization one day later.[10] When the German Empire began to mobilize on 30 July 1914, France—sporting significant animosity over the German conquest of Alsace-Lorraine during the Franco-Prussian War—ordered French mobilization on 1 August. Germany declared war on Russia the same day.[18]
Chronology
Opening hostilities
Confusion among the Central Powers
The strategy of the Central Powers suffered from miscommunication. Germany had promised to support Austria-Hungary’s invasion of Serbia, but interpretations of what this meant differed. Austro-Hungarian leaders believed Germany would cover its northern flank against Russia.[citation needed] Germany, however, envisioned Austria-Hungary directing the majority of its troops against Russia, while Germany dealt with France. This confusion forced the Austro-Hungarian Army to divide its forces between the Russian and Serbian fronts.
On 9 September 1914 the Septemberprogramm, a plan which detailed Germany's specific war aims and the conditions that Germany sought to force upon the Allied Powers, was outlined by German Chancellor Theobald von Bethmann Hollweg.
African campaigns
Main article: African theatre of World War I
Some of the first clashes of the war involved British, French and German colonial forces in Africa. On 7 August, French and British troops invaded the German protectorate of Togoland. On 10 August German forces in South-West Africa attacked South Africa; sporadic and fierce fighting continued for the remainder of the war.

Serbian campaign
Main article: Serbian Campaign (World War I)
The Serbian army fought the Battle of Cer against the invading Austrians, beginning on 12 August, occupying defensive positions on the south side of the Drina and Sava rivers. Over the next two weeks Austrian attacks were thrown back with heavy losses, which marked the first major Allied victory of the war and dashed Austrian hopes of a swift victory. As a result, Austria had to keep sizable forces on the Serbian front, weakening its efforts against Russia.
German forces in Belgium and France

Main article: Western Front (World War I)
The German attack on the Western Front began with an invasion through neutral Belgium. Initially, the Germans had great success in the Battle of the Frontiers (14 August–24 August). Russia, however, attacked in East Prussia and diverted German forces intended for the Western Front. Germany defeated Russia in a series of battles collectively known as the First Battle of Tannenberg (17 August – 2 September), but this diversion exacerbated problems of insufficient speed of advance from rail-heads not foreseen by the German General Staff. The Schlieffen Plan called for the right flank of the German advance to converge on Paris, but the French, with some assistance from the British forces finally halted the German advance east of Paris at the First Battle of the Marne (5 September–12 September). The Central Powers were thereby denied a quick victory and forced to fight 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. Despite this, communications problems and questionable command decisions cost Germany the chance of obtaining an early victory.
Asia and the Pacific
Main article: Asian and Pacific theatre of World War I
New Zealand occupied German Samoa (later Western Samoa) on 30 August. On 11 September the Australian Naval and Military Expeditionary Force landed on the island of Neu Pommern (later New Britain), which formed part of German New Guinea. Japan seized Germany's Micronesian colonies and after the Battle of Tsingtao, the German coaling port of Qingdao, in the Chinese Shandong peninsula. Within a few months, the Allied forces had seized all the German territories in the Pacific.

Main article: Western Front (World War I)
Military tactics before World War I had failed to keep pace with advances in technology. These changes resulted in the building of impressive defence systems, which out-of-date tactics could not break through for most of the war. Barbed wire was a significant hindrance to massed infantry advances. Artillery, vastly more lethal than in the 1870s, coupled with machine guns, made crossing open ground very difficult. The Germans introduced poison gas; it soon became used by both sides, though it never proved decisive in winning a battle. Its effects were brutal, causing slow and painful death, and poison gas became one of the most-feared and best-remembered horrors of the war. Commanders on both sides failed to develop tactics for breaching entrenched positions without heavy casualties. In time, however, technology began to produce new offensive weapons, such as the tank. Britain and France were its primary users; the Germans employed captured Allied tanks and small numbers of their own design.
After the First Battle of the Marne, both Entente and German forces began a series of outflanking maneuvers, in the so-called 'Race to the Sea'. Britain and France soon found themselves facing entrenched German forces from Lorraine to Belgium's Flemish coast. Britain and France sought to take the offensive, while Germany defended the occupied territories; consequently, German trenches were generally much better constructed than those of their enemy. Anglo-French trenches were only intended to be 'temporary' before their forces broke through German defenses. Both sides attempted to break the stalemate using scientific and technological advances. In April 1915 the Germans used chlorine gas for the first time (in violation of the Hague Convention), opening a six kilometre (four mile) hole in the Allied lines when British and French colonial troops retreated. Canadian soldiers closed the breach at the Second Battle of Ypres. At the Third Battle of Ypres, Canadian and ANZAC troops took the village of Passchendaele.
The British Army endured the bloodiest day in its history, suffering 57,470 casualties and 19,240 dead on 1 July 1916, the first day of the Battle of the Somme. Most of the casualties occurred in the first hour of the attack. The entire Somme offensive cost the British Army almost half a million men.[19]

Neither side proved able to deliver a decisive blow for the next two years, though protracted German action at Verdun throughout 1916, combined with the Entente's failure at the Somme,[citation needed] brought the exhausted French army to the brink of collapse. Futile attempts at frontal assault, a rigid adherence to an ineffectual method,[citation needed] came at a high price for both the British and the French poilu (infantry) and led to widespread mutinies, especially during the Nivelle Offensive.

Throughout 1915–17, the British Empire and France suffered more casualties than Germany, due both to the strategic and tactical stances chosen by the sides. At the strategic level, while the Germans only mounted a single main offensive at Verdun, the Allies made several attempts to break through German lines. At the tactical level, the German defensive doctrine was well suited for trench warfare, with a relatively lightly defended "sacrificial" forward position,[citation needed] and a more powerful main position from which an immediate and powerful counter-offensive could be launched. This combination usually was effective in pushing out attackers at a relatively low cost to the Germans.[citation needed] In absolute terms, of course, the cost in lives of men for both attack and defense was astounding.
Ludendorff wrote on the fighting in 1917, "The 25th of August concluded the second phase of the Flanders battle. It had cost us heavily…. The costly August battles in Flanders and at Verdun imposed a heavy strain on the Western troops. In spite of all the concrete protection they seemed more or less powerless under the enormous weight of the enemy’s artillery. At some points they no longer displayed the firmness which I, in common with the local commanders, had hoped for. The enemy managed to adapt himself to our method of employing counter attacks… I myself was being put to a terrible strain. The state of affairs in the West appeared to prevent the execution of our plans elsewhere. Our wastage had been so high as to cause grave misgivings, and had exceeded all expectation."
On the battle of the Menin Road Ridge Ludendorff wrote: "Another terrific assault was made on our lines on the 20 September…. The enemy’s onslaught on the 20th was successful, which proved the superiority of the attack over the defence. Its strength did not consist in the tanks; we found them inconvenient, but put them out of action all the same. The power of the attack lay in the artillery, and in the fact that ours did not do enough damage to the hostile infantry as they were assembling, and above all, at the actual time of the assault."[20]

Around 800,000 soldiers from the British Empire were on the Western Front at any one time.[citation needed] 1,000 battalions, occupying sectors of the line from the North Sea to the Orne River, operated on a month-long four-stage rotation system, unless an offensive was underway. The front contained over 9,600 kilometres (5,965 mi) of trenches. Each battalion held its sector for about 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 1917 Battle of Arras the only significant British military success was the capture of Vimy Ridge by the Canadian Corps under Sir Arthur Currie and Julian Byng. The assaulting troops were able for the first time to overrun, rapidly reinforce and hold the ridge defending the coal-rich Douai plain.[21][22]
Naval war
Main article: Naval Warfare of World War I
The British Grand Fleet
At the start of the war, the German Empire had cruisers scattered across the globe, some of which were subsequently used to attack Allied merchant shipping. The British Royal Navy systematically hunted them down, though not without some embarrassment from its inability to protect Allied shipping. For example, the German detached light cruiser SMS Emden, part of the East-Asia squadron stationed at Tsingtao, seized or destroyed 15 merchantmen, as well as sinking a Russian cruiser and a French destroyer. However, the bulk of the German East-Asia squadron—consisting of the armoured cruisers Scharnhorst and Gneisenau, light cruisers Nürnberg and Leipzig and two transport ships—did not have orders to raid shipping and was instead underway to Germany when it encountered elements of the British fleet. The German flotilla, along with Dresden, sank two armoured cruisers at the Battle of Coronel, but was almost completely destroyed at the Battle of the Falkland Islands in December 1914, with only Dresden and a few auxiliaries escaping, but at the Battle of Más a Tierra these too were destroyed or interned.[23]
Soon after the outbreak of hostilities, Britain initiated a naval blockade of Germany. The strategy proved effective, cutting off vital military and civilian supplies, although this blockade violated generally accepted international law codified by several international agreements of the past two centuries.[24] Britain mined international waters to prevent any ships from entering entire sections of ocean, causing danger to even neutral ships.[25] Since there was limited response to this tactic, Germany expected a similar response to its unrestricted submarine warfare.[26]
A battleship squadron of the Hochseeflotte at sea
The 1916 Battle of Jutland (German: Skagerrakschlacht, or "Battle of the Skagerrak") developed into the largest naval battle of the war, the only full-scale clash of battleships during the war. It took place on 31 May–1 June 1916, in the North Sea off Jutland. The Kaiserliche Marine's High Seas Fleet, commanded by Vice Admiral Reinhard Scheer, squared off against the Royal Navy's Grand Fleet, led by Admiral Sir John Jellicoe. The engagement was a standoff, as the Germans, outmaneuvered by the larger British fleet, managed to escape and inflicted more damage to the British fleet than they received. Strategically, however, the British asserted their control of the sea, and the bulk of the German surface fleet remained confined to port for the duration of the war.
German U-boats attempted to cut the supply lines between North America and Britain.[27] The nature of submarine warfare meant that attacks often came without warning, giving the crews of the merchant ships little hope of survival.[28] The United States launched a protest, and Germany modified its rules of engagement. After the notorious sinking of the passenger ship RMS Lusitania in 1915, Germany promised not to target passenger liners, while Britain armed its merchant ships, placing them beyond the protection of the "cruiser rules" which demanded warning and placing crews in "a place of safety" (a standard which lifeboats did not meet).[29] Finally, in early 1917 Germany adopted a policy of unrestricted submarine warfare, realizing the Americans would eventually enter the war.[30] Germany sought to strangle Allied sea lanes before the U.S. could transport a large army overseas.
The U-boat threat lessened in 1917, when merchant ships entered convoys escorted by destroyers. This tactic made it difficult for U-boats to find targets, which significantly lessened losses; after the introduction of hydrophone and depth charges, accompanying destroyers might actually attack a submerged submarine with some hope of success. The convoy system slowed the flow of supplies, since ships had to wait as convoys were assembled. The solution to the delays was a massive program to build new freighters. Troop ships were too fast for the submarines and did not travel the North Atlantic in convoys.[31][32] The U-boats had sunk almost 5,000 Allied ships, at a cost of 178 submarines.[33]
World War I also saw the first use of aircraft carriers in combat, with HMS Furious launching Sopwith Camels in a successful raid against the Zeppelin hangars at Tondern in July 1918, as well as blimps for antisubmarine patrol.[34]

War in the Balkans
Main articles: Balkans Campaign (World War I), Serbian Campaign (World War I), and Macedonian front (World War I)
Faced with Russia, Austria-Hungary could spare only one third of its army to attack Serbia. After suffering heavy losses, the Austrians briefly occupied the Serbian capital, Belgrade. A Serbian counterattack in the battle of Kolubara, however, succeeded in driving them from the country by the end of 1914. For the first ten months of 1915, Austria-Hungary used most of its military reserves to fight Italy. German and Austro-Hungarian diplomats, however, scored a coup by convincing Bulgaria to join in attacking Serbia. The Austro-Hungarian provinces of Slovenia, Croatia and Bosnia provided troops for Austria-Hungary, invading Serbia as well as fighting Russia and Italy. Montenegro allied itself with Serbia.
Serbia was conquered in a little more than a month. The attack began in October, when the Central Powers launched an offensive from the north; four days later the Bulgarians joined the attack from the east. The Serbian army, fighting on two fronts and facing certain defeat, retreated into Albania, halting only once in order to make a stand against the Bulgarians. The Serbs suffered defeat near modern day Gnjilane in the Battle of Kosovo[citation needed]. Montenegro covered the Serbian retreat toward the Adriatic coast in the Battle of Mojkovac in 6-7 January 1916, but ultimately the Austrians conquered Montenegro, too. Serbian forces were evacuated by ship to Greece.

In late 1915 a Franco-British force landed at Salonica in Greece, to offer assistance and to pressure the government to declare war against the Central Powers. Unfortunately for the Allies, the pro-German King Constantine I dismissed the pro-Allied government of Eleftherios Venizelos, before the Allied expeditionary force could arrive.
After conquest, Serbia was divided between Austro-Hungary and Bulgaria. Bulgarians commenced bulgarization of the Serbian population in their occupation zone, banishing Serbian Cyrillic and the Serbian Orthodox Church. After forced conscription of the Serbian population into the Bulgarian army in 1917, the Toplica Uprising began. Serbian rebels liberated for a short time the area between the Kopaonik mountains and the South Morava river. The uprising was crushed by joint efforts of Bulgarian and Austrian forces at the end of March 1917.
The Macedonian Front proved static for the most part. Serbian forces retook part of Macedonia by recapturing Bitola on 19 November 1916. Only at the end of the conflict were the Entente powers able to break through, after most of the German and Austro-Hungarian troops had withdrawn. The Bulgarians suffered their only defeat of the war at the Battle of Dobro Pole but days later, they decisively defeated British and Greek forces at the Battle of Doiran, avoiding occupation. Bulgaria signed an armistice on 29 September 1918.
Ottoman Empire

British artillery placements during the Battle of Jerusalem (1917)
The Ottoman Empire joined the Central Powers in the war, the secret Ottoman-German Alliance having been signed in August 1914. It threatened Russia's Caucasian territories and Britain's communications with India via the Suez Canal. The British and French opened overseas fronts with the Gallipoli (1915) and Mesopotamian campaigns. In Gallipoli, the Turks successfully repelled the British, French and Australian and New Zealand Army Corps (ANZACs). In Mesopotamia, by contrast, after the disastrous Siege of Kut (1915–16), British Imperial forces reorganised and captured Baghdad in March 1917. Further to the west, in the Sinai and Palestine Campaign, initial British setbacks were overcome when Jerusalem was captured in December 1917. The Egyptian Expeditionary Force, under Field Marshal Edmund Allenby, broke the Ottoman forces at the Battle of Megiddo in September 1918.
Russian armies generally had the best of it in the Caucasus. Enver Pasha, supreme commander of the Turkish armed forces, was ambitious and dreamed of conquering central Asia. He was, however, a poor commander.[35] He launched an offensive against the Russians in the Caucasus in December 1914 with 100,000 troops; insisting on a frontal attack against mountainous Russian positions in winter, he lost 86% of his force at the Battle of Sarikamis.[36]
The Russian commander from 1915 to 1916, General Yudenich, drove the Turks out of most of the southern Caucasus with a string of victories.[36] In 1917, Russian Grand Duke Nicholas assumed command of the Caucasus front. Nicholas planned a railway from Russian Georgia to the conquered territories, so that fresh supplies could be brought up for a new offensive in 1917. However, in March 1917, (February in the pre-revolutionary Russian calendar), the Czar was overthrown in the February Revolution and the Russian Caucasus Army began to fall apart. In this situation, the army corps of Armenian volunteer units realigned themselves under the command of General Tovmas Nazarbekian, with Dro as a civilian commissioner of the Administration for Western Armenia. The front line had three main divisions: Movses Silikyan, Andranik, and Mikhail Areshian. Another regular unit was under Colonel Korganian. There were Armenian partisan guerrilla detachments (more than 40,000[37]) accompanying these main units.
The Arab Revolt (described in Lawrence of Arabia) was a major cause of the Ottoman Empire's defeat. The revolts started with the Battle of Mecca by Sherif Hussain of Mecca with the help of Britain in June 1916, and ended with the Ottoman surrender of Damascus. Fakhri Pasha the Ottoman commander of Medina showed stubborn resistance for over two and half years during the Siege of Medina.
Along the border of Italian Libya and British Egypt, the Senussi tribe, incited and armed by the Turks, waged a small-scale guerrilla war against Allied troops. According to Martin Gilbert's The First World War, the British were forced to dispatch 12,000 troops to deal with the Senussi. Their rebellion was finally crushed in mid-1916.
Italian participation
Main article: Italian Campaign (World War I)
Austro-Hungarian mountain corps in Tyrol
Italy had been allied with the German and Austro-Hungarian Empires since 1882 as part of the Triple Alliance. However, the nation had its own designs on Austrian territory in Trentino, Istria and Dalmatia. Rome had a secret 1902 pact with France, effectively nullifying its alliance.[citation needed] At the start of hostilities, Italy refused to commit troops, arguing that the Triple Alliance was defensive in nature, and that Austria-Hungary was an aggressor. The Austro-Hungarian government began negotiations to secure Italian neutrality, offering the French colony of Tunisia in return. The Allies made a counter-offer in which Italy would receive the Alpine province of Alto Adige and territory on the Dalmatian coast after the defeat of Austria-Hungary. This was fomalised by the Treaty of London. Further encouraged by the Allied invasion of Turkey in April 1915, Italy joined the Entente and declared war on Austria-Hungary on May 23. Fifteen months later Italy declared war on Germany.
Militarily, the Italians had numerical superiority. This advantage, however, was lost, not only because of the difficult terrain in which fighting took place, but also because of the strategies and tactics employed. Field Marshal Luigi Cadorna, a staunch proponent of the frontal assault, had dreams of breaking into the Slovenian plateau, taking Ljubljana and threatening Vienna. It was a Napoleonic plan, which had no realistic chance of success in an age of barbed wire, machine guns, and indirect artillery fire, combined with hilly and mountainous terrain.
On the Trentino front, the Austro-Hungarians took advantage of the mountainous terrain, which favoured the defender. After an initial strategic retreat, the front remained largely unchanged, while Austrian Kaiserschützen and Standschützen (German wikipedia) engaged Italian Alpini in bitter hand-to-hand combat throughout the summer. The Austro-Hungarians counter-attacked in the Altopiano of Asiago, towards Verona and Padua, in the spring of 1916 (Strafexpedition), but made little progress.
Beginning in 1915, the Italians under Cadorna mounted eleven offensives on the Isonzo front along the Isonzo River, north-east of Trieste. All eleven offensives were repelled by the Austro-Hungarians, who held the higher ground. In the summer of 1916, the Italians captured the town of Gorizia. After this minor victory, the front remained static for over a year, despite several Italian offensives. In the autumn of 1917, thanks to the improving situation on the Eastern front, the Austrians received large numbers of reinforcements, including German Stormtroopers and the elite Alpenkorps. The Central Powers launched a crushing offensive on 26 October 1917, spearheaded by the Germans. They achieved a victory at Caporetto. The Italian army was routed and retreated more than 100 km (60 miles) to reorganise, stabilizing the front at the Piave River. Since in the Battle of Caporetto Italian Army had heavy losses, the Italian Government called to arms the so called '99 Boys (Ragazzi del '99), that is, all males who were 18 years old. In 1918, the Austro-Hungarians failed to break through, in a series of battles on the Asiago Plateau, finally being decisively defeated in the Battle of Vittorio Veneto in October of that year. Austria-Hungary surrendered in early November 1918.[38][39][40]

Fighting in India
The war began with an unprecedented outpouring of loyalty and goodwill towards the United Kingdom from within the mainstream political leadership, contrary to initial British fears of an Indian revolt. India under British rule contributed massively to the British war effort by providing men and resources. This was done by the Indian Congress in hope of achieving self-government as India was very much under the control of the British. The United Kingdom disappointed the Indians by not providing self-governance, leading to the Gandhiian Era in Indian history. About 1.3 million Indian soldiers and labourers served in Europe, Africa, and the Middle East, while both the Indian government and the princes sent large supplies of food, money, and ammunition. In all 140,000 men served on the Western Front and nearly 700,000 in the Middle East. 47,746 Indian soldiers were killed and 65,126 wounded during World War I.[41]
Indian independence movement
Bengal and Punjab remained hotbeds of anti-colonial activities. Terrorism in Bengal, increasingly closely linked with the unrests in Punjab, was significant enough to nearly paralyse the regional administration. Also from the beginning of the war, expatriate Indian population, notably in Germany, United States and Canada, headed by the Indian Independence Committee and the Ghadar Party respectively, attempted to trigger insurrections in India on the lines of the 1857 uprising with Irish Republican, German and Turkish help in a massive conspiracy that has since come to be called the Hindu German conspiracy. The conspiracy also made attempts to rally the Amir of Afghanistan against British India, starting a political process in that country that culminated three years later in the assassination of Amir Habibullah and precipitation of the Third Anglo-Afghan war. A number of failed attempts at mutiny were made in India, of which the February mutiny plan and the Singapore mutiny remain most notable. This movement was suppressed by means of a massive international counter-intelligence operation and draconian political acts (including the Defence of India act 1915) that lasted nearly ten years.[42][43][44]
The Ghadarites also attempted to organise incursions from the western border of India, recruiting Indian prisoners of war from Turkey, Germany, Mesopotamia. Ghadarite rebels, led by Sufi Amba Prasad, fought along with Turkish forces in Iran and in Turkey. Plans were made in Constantinopole to organise a campaign from Persia, through Baluchistan, to Punjab. These forces were involved skirmishes that captured the frontier city of Karman, taking into custody the British consul. Percy Sykes's campaign in Persia was directed mostly against these composite forces. It was at this time that the Aga Khan and his brother were recruited into the British War effort. However, the Aga Khan's brother was captured and shot dead by the rebels, who also successfully harassed British Forces in Sistan in Afghanistan, confining British forces to Karamshir in Baluchistan, later moving towards Karachi. They were able to take control of the coastal towns of Gawador and Dawar. The Baluchi chief of Bampur, having declared his independence from the British rule, also joined the Ghadarite forces. It was not before the war in Europe turned for the worse for Turkey and Baghdad was captured by the British forces that the Ghadarite forces, their supply lines starved, were finally dislodged. They retreated to regroup at Shiraz, where they were finally defeated after a bitter fight. Amba Prasad Sufi was killed in this battle. The Ghadarites carried on guerrilla warfare along with the Iranian partisans till 1919.[45][46][47][48]
Although the conflict in India was not explicitly a part of the First World War, it was part of the wider strategic context. The British attempt to subjugate the rebelling tribal leaders drew away much needed troops from other theaters, in particular, of course, the Western Front, where the real decisive victory would be made.
The reason why some Indian and Afghani tribes rose up simply came down to years of discontent which erupted, probably not coincidentally, during the First World War. It is likely that the tribal leaders were aware that Britain would not be able to field the required men, in terms of either number or quality, but underestimated the strategic importance of India to the British. Despite being far from the epicenter of the conflict, India provided a bounty of men for the fronts. Its produce was also needed for the British war effort and many trade routes running to other profitable areas of the Empire ran through India. Therefore, although the British were not able to send the men that they wanted, they were able to send enough to mount a gradual but effective counter-guerrilla war against the tribesmen. The fighting continued into 1919 and in some areas lasted even longer.

Initial actions
Main article: Eastern Front (World War I)
While the Western Front had reached stalemate, the war continued in East Europe. Initial Russian plans called for simultaneous invasions of Austrian Galicia and German East Prussia. Although Russia's initial advance into Galicia was largely successful, they were driven back from East Prussia by Hindenburg and Ludendorff at Tannenberg and the 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 had retreated into Galicia, and in May the Central Powers achieved a remarkable breakthrough on Poland's southern frontiers. On 5 August they captured Warsaw and forced the Russians to withdraw from Poland.

Russian Revolution
Main article: 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. The success was undermined by the reluctance of other generals to commit their forces to support the victory. Allied and Russian forces were revived only temporarily with Romania's entry into the war on 27 August. German forces came to the aid of embattled Austrian units in Transylvania and Bucharest fell to the Central Powers on 6 December. Meanwhile, unrest grew in Russia, as the Tsar remained at the front. Empress Alexandra's increasingly incompetent rule drew protests and resulted in the murder of her favourite, Rasputin, at the end of 1916.
Vladimir Illyich Lenin
In March 1917, demonstrations in Petrograd culminated in the abdication of Tsar Nicholas II and the appointment of a weak Provisional Government which shared power with the Petrograd Soviet socialists. This arrangement led to confusion and chaos both at the front and at home. The army became increasingly ineffective.
The war and the government became more and more unpopular. Discontent led to a rise in popularity of the Bolshevik party, led by Vladimir Lenin. He promised to pull Russia out of the war and was able to gain power. The triumph of the Bolsheviks in November was followed in December by an armistice and negotiations with Germany. At first the Bolsheviks refused the German terms, but when Germany resumed the war and marched across Ukraine with impunity, the new government acceded to the Treaty of Brest-Litovsk on 3 March 1918. It took Russia out of the war and ceded vast territories, including Finland, the Baltic provinces, parts of Poland and Ukraine to the Central Powers. The manpower required for German occupation of former Russian territory may have contributed to the failure of the Spring Offensive, however, and secured relatively little food or other war materiel.
With the Bolsheviks' accession to the Treaty of Brest-Litovsk, the Entente no longer existed. The Allied powers led a small-scale invasion of Russia to stop Germany from exploiting Russian resources and, to a lesser extent, to support the Whites in the Russian Civil War. Allied troops landed in Archangel and in Vladivostok.

Events of 1917 proved decisive in ending the war, although their effects were not fully felt until 1918. The British naval blockade began to have a serious impact on Germany. In response, in February 1917, the German General Staff convinced 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 to July. It peaked at 860,000 tons in April. After July, the reintroduced convoy system became extremely effective in neutralizing the U-boat threat. Britain was safe from starvation and German industrial output fell.
On 3 May 1917 during the Nivelle Offensive the weary French 2nd Colonial Division, veterans of the Battle of Verdun, refused their orders, arriving drunk and without their weapons. Their officers lacked the means to punish an entire division, and harsh measures were not immediately implemented. There upon the mutinies afflicted 54 French divisions and saw 20,000 men desert. The other Allied forces attacked but received massive casualties.[49] However, appeals to patriotism and duty, as well as mass arrests and trials, encouraged the soldiers to return to defend their trenches, although the French soldiers refused to participate in further offensive action.[50] Robert Nivelle was removed from command by 15 May, replaced by General Philippe Pétain, who suspended large-scale attacks. The French would go on the defensive for the next year, leaving the burden of attack to Britain, her Empire and other allies, and subsequently the United States.
The victory of Austria-Hungary and Germany at the Battle of Caporetto led the Allies at the Rapallo Conference to form the Supreme War Council to coordinate planning. Previously, British and French armies had operated under separate commands.
In December, the Central Powers signed an armistice with Russia. This released troops for use in the west. Ironically, German troop transfers could have been greater if their territorial acquisitions had not been so dramatic. With German reinforcements and new American troops pouring in, the final outcome was to be decided on the Western front. The Central Powers knew that they could not win a protracted war, but they held high hopes for a quick offensive. Furthermore, the leaders of the Central Powers and the Allies became increasingly fearful of social unrest and revolution in Europe. Thus, both sides urgently sought a decisive victory.[51]
In December 1916, the Germans attempted to negotiate peace with the Allies, declaring themselves the victors. The Allies rejected the offer. This German poster from January 1917 quotes a speech by Kaiser Wilhelm II lambasting them for their decision.

Isolationism
The United States originally pursued a policy of isolationism, avoiding conflict while trying to broker a peace. This resulted in increased tensions with Berlin and London. When a German U-boat sank the British liner Lusitania in 1915, with 128 Americans aboard, U.S. President Woodrow Wilson vowed, "America is too proud to fight" and demanded an end to attacks on passenger ships. Germany complied. Wilson unsuccessfully tried to mediate a settlement. He repeatedly warned the U.S. would not tolerate unrestricted submarine warfare, in violation of international law and U.S. ideas of human rights. Wilson was under pressure from former president Theodore Roosevelt, who denounced German acts as "piracy".[52] Wilson's desire to have a seat at negotiations at war's end to advance the League of Nations also played a role.[53] Wilson's Secretary of State, William Jennings Bryan, resigned in protest of the President's decidedly warmongering diplomacy. Other factors contributing to the U.S. entry into the war include the suspected German sabotage of both Black Tom in Jersey City, New Jersey, and the Kingsland Explosion in what is now Lyndhurst, New Jersey.
Making the case
In January 1917, after the Navy pressured the Kaiser, Germany resumed unrestricted submarine warfare. Britain's secret Royal Navy cryptanalytic group, Room 40, had broken the German diplomatic code. They intercepted a proposal from Berlin (the Zimmermann Telegram) to Mexico to join the war as Germany's ally against the United States, should the U.S. join. The proposal suggested, if the U.S. were to enter the war, Mexico should declare war against the United States and enlist Japan as an ally. This would prevent the United States from joining the Allies and deploying troops to Europe, and would give Germany more time for their unrestricted submarine warfare program to strangle Britain's vital war supplies. In return, the Germans would promise Mexico support in reclaiming Texas, New Mexico, and Arizona.[54]
U.S. declaration of war on Germany
After the British revealed the telegram to the United States, President Wilson, who had won reelection on his keeping the country out of the war, released the captured telegram as a way of building support for U.S. entry into the war. He had previously claimed neutrality, while calling for the arming of U.S. merchant ships delivering munitions to combatant Britain and quietly supporting the British blockading of German ports and mining of international waters, preventing the shipment of food from America and elsewhere to combatant Germany. After submarines sank seven U.S. merchant ships and the publication of the Zimmerman telegram, Wilson called for war on Germany, which the U.S. Congress declared on 6 April 1917.[55]
Crucial to U.S. participation was the massive domestic propaganda campaign executed by the Committee on Public Information overseen by George Creel. The campaign included tens of thousands of government-selected community leaders giving brief carefully scripted pro-war speeches at thousands of public gatherings. Along with other branches of government and private vigilante groups like the American Protective League, it also included the general repression and harassment of people either opposed to American entry into the war or of German heritage. Other forms of propaganda included newsreels, photos, large-print posters (designed by several well-known illustrators of the day, including Louis D. Fancher and Henry Reuterdahl), magazine and newspaper articles, etc.
First active U.S. participation

The United States was never formally a member of the Allies but became a self-styled "Associated Power". The United States had a small army, but it drafted four million men and by summer 1918 was sending 10,000 fresh soldiers to France every day. In 1917, the U.S. Congress gave U.S. citizenship to Puerto Ricans when they were drafted to participate in World War I, as part of the Jones Act. Germany had miscalculated, believing it would be many more months before they would arrive and that the arrival could be stopped by U-boats.[57]
M1905 Howitzer used by Allied Forces
The United States Navy sent a battleship group to Scapa Flow to join with the British Grand Fleet, destroyers to Queenstown, Ireland and submarines to help guard convoys. Several regiments of U.S. Marines were also dispatched to France. The British and French wanted U.S. units used to reinforce their troops already on the battle lines and not waste scarce shipping on bringing over supplies. The U.S. rejected the first proposition and accepted the second. General John J. Pershing, American Expeditionary Force (AEF) commander, refused to break up U.S. units to be used as reinforcements for British Empire and French units. As an exception, he did allow African-American combat regiments such as the Harlem Hellfighters to be used in French divisions.[58]AEF doctrine called for the use of frontal assaults, which had long since been discarded by British Empire and French commanders because of the large loss of life.[59]
German Spring Offensive of 1918
Main article: Spring Offensive
For most of World War I, Allied forces were stalled at trenches on the Western Front
German General Erich Ludendorff drew up plans (codenamed Operation Michael) for the 1918 offensive on the Western Front. The Spring Offensive sought to divide the British and French forces with a series of feints and advances. The German leadership hoped to strike a decisive blow before significant U.S. forces arrived. The operation commenced on 21 March 1918 with an attack on British forces near Amiens. German forces achieved an unprecedented advance of 60 kilometers (40 miles).[60]
British and French trenches were penetrated using novel infiltration tactics, also named Hutier tactics, after General Oskar von Hutier. Previously, attacks had been characterised by long artillery bombardments and massed assaults.[citation needed] However, in the Spring Offensive, the German Army used artillery only briefly and infiltrated small groups of infantry at weak points. They attacked command and logistics areas and bypassed points of serious resistance. More heavily armed infantry then destroyed these isolated positions. German success relied greatly on the element of surprise.[citation needed]
The front moved to within 120 kilometers (75 mi) of Paris. Three heavy Krupp railway guns fired 183 shells on the capital, causing many Parisians to flee. The initial offensive was so successful that Kaiser Wilhelm II declared 24 March a national holiday. Many Germans thought victory was near. After heavy fighting, however, the offensive was halted. Lacking tanks or motorised artillery, the Germans were unable to consolidate their gains. The sudden stop was also a result of the four AIF (Australian Imperial Forces) divisions that were "rushed" down, thus doing what no other army had done and stopping the German advance in its tracks. During that time the first Australian division was hurriedly sent north again to stop the second German breakthrough.

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 War Council of Allied forces was created at the Doullens Conference on 5 November 1917.[61] General Foch was appointed as supreme commander of the allied forces. Haig, Petain and Pershing retained tactical control of their respective armies; Foch assumed a coordinating role, rather than a directing role and the British, French and U.S. commands operated largely independently.[61]
Following Operation Michael, Germany launched Operation Georgette against the northern English channel ports. The Allies halted the drive with limited territorial gains for Germany. The German Army to the south then conducted Operations Blücher and Yorck, broadly towards Paris. Operation Marne was launched on 15 July, attempting to encircle Reims and beginning the Second Battle of the Marne. The resulting Allied counterattack marked their first successful offensive of the war.
By 20 July the Germans were back at their Kaiserschlacht starting lines,[citation needed] having achieved nothing. Following this last phase of the war in the West, the German Army never again regained the initiative. German casualties between March and April 1918 were 270,000, including many highly trained stormtroopers.
Meanwhile, Germany was falling apart at home. Anti-war marches become frequent and morale in the army fell. Industrial output was 53% of 1913 levels.
New states under war zone
In 1918, the internationally recognized Democratic Republic of Armenia and Democratic Republic of Georgia bordering the Ottoman Empire were established, as well as the unrecognized Centrocaspian Dictatorship and South West Caucasian Republic.
In 1918, the Dashnaks of the Armenian national liberation movement declared the Democratic Republic of Armenia (DRA) through the Armenian Congress of Eastern Armenians (unified form of Armenian National Councils) after the dissolution of the Transcaucasian Democratic Federative Republic. Tovmas Nazarbekian became the first Commander-in-chief of the DRA. Enver Pasha ordered the creation of a new army to be named the Army of Islam. He ordered the Army of Islam into the DRA, with the goal of taking Baku on the Caspian Sea. This new offensive was strongly opposed by the Germans. In early May 1918, the Ottoman army attacked the newly declared DRA. Although the Armenians managed to inflict one defeat on the Ottomans at the Battle of Sardarapat, the Ottoman army won a later battle and scattered the Armenian army. The Republic of Armenia was forced to sign the Treaty of Batum in June 1918.
Allied victory: summer and autumn 1918
Main articles: Hundred Days Offensive and Weimar Republic

The Allied counteroffensive, known as the Hundred Days Offensive, began on 8 August 1918. The Battle of Amiens developed with III Corps Fourth British Army on the left, the First French Army on the right, and the Australian and Canadian Corps spearheading the offensive in the centre through Harbonnières.[62][63] It involved 414 tanks of the Mark IV and Mark V type, and 120,000 men. They advanced 12 kilometers (7 miles) into German-held territory in just seven hours. Erich Ludendorff referred to this day as the "Black Day of the German army".[62][64]
The Australian-Canadian spearhead at Amiens, a battle that was the beginning of Germany’s downfall,[20] helped pull the British armies to the north and the French armies to the south forward. While German resistance on the British Fourth Army front at Amiens stiffened, after an advance as far as 14 miles (23 km) and brought the battle there to an end, the French Third Army lengthened the Amiens front on 10 August, when it was thrown in on the right of the French First Army, and advanced 4 miles (6 km) liberating Lassigny in fighting which lasted until the 16th. South of the French Third Army General Mangin (The Butcher) drove his French Tenth Army forward at Soissons on 20 August to capture eight thousand prisoners, two hundred guns and the Aisne heights overlooking and menacing the German position north of the Vesle.[65] Another "Black day" as described by Ludendorff.
Meanwhile General Byng of the Third British Army, reporting that the enemy on his front was thinning in a limited withdrawal, was ordered to attack with 200 tanks toward Bapaume, opening what is known as the Battle of Albert with the specific orders of "To break the enemy's front, in order to outflank the enemies present battle front" (opposite the British Fourth Army at Amiens).[20] Allied leaders had now realized that to continue an attack after resistance had hardened was a waste of lives and it was better to turn a line than to try and roll over it. Attacks were being undertaken in quick order to take advantage of the successful advances on the flanks and then broken off when that attack lost its initial impetus.[65]
The British Third Army's 15-mile (24 km) front north of Albert progressed after stalling for a day against the main resistance line to which the enemy had withdrawn.[66] Rawlinson’s Fourth British Army was able to battle its left flank forward between Albert and the Somme straightening the line between the advanced positions of the Third Army and the Amiens front which resulted in recapturing Albert at the same time.[65] On 26 August the British First Army on the left of the Third Army was drawn into the battle extending it northward to beyond Arras. The Canadian Corps already being back in the vanguard of the First Army fought their way from Arras eastward 5 miles (8 km) astride the heavily defended Arras-Cambrai before reaching the outer defenses of the Hindenburg line, breaching them on the 28th and 29th. Bapaume fell on the 29th to the New Zealand Division of the Third Army and the Australians, still leading the advance of the Fourth Army, were again able to push forward at Amiens to take Peronne and Mont St. Quentin on August 31. Further south the French First and Third Armies had slowly fought forward while the Tenth Army, who had by now crossed the Ailette and was east of the Chemin des Dames, was now near to the Alberich position of the Hindenburg line.[67] During the last week of August the pressure along a 70-mile (113 km) front against the enemy was heavy and unrelenting. From German accounts, "Each day was spent in bloody fighting against an ever and again on-storming enemy, and nights passed without sleep in retirements to new lines."[65] Even to the north in Flanders the British Second and Fifth Armies during August and September were able to make progress taking prisoners and positions that were previously denied them.[67]

On 2 September the Canadian Corps outflanking of the Hindenburg line, with the breaching of the Wotan Position, made it possible for the Third Army to advance and sent repercussions all along the Western Front. That same day OHL had no choice but to issue orders to six armies for withdrawal back into the Hindenburg line in the south, behind the Canal Du Nord on the Canadian-First Army's front and back to a line east of the Lys in the north, giving up without a fight the salient seized in the previous April.[68] According to Ludendorff “We had to admit the necessity…to withdraw the entire front from the Scarpe to the Vesle.”[69]
In nearly four weeks of fighting since 8 August over 100,000 German prisoners were taken, 75,000 by the BEF and the rest by the French. Since "The Black Day of the German Army" the German High Command realized the war was lost and made attempts for a satisfactory end. The day after the battle Ludenforff told Colonel Mertz "We cannot win the war any more, but we must not lose it either." On 11 August he offered his resignation to the Kaiser, who refused it and replied, "I see that we must strike a balance. We have nearly reached the limit of our powers of resistance. The war must be ended." On 13 August at Spa, Hindenburg, Ludendorff, Chancellor and Foreign minister Hintz agreed that the war could not be ended militarily and on the following day the German Crown Council decided victory in the field was now most improbable. Austria and Hungary warned that they could only continue the war until December and Ludendorff recommended immediate peace negotiations, to which the Kaiser responded by instructing Hintz to seek the Queen of Holland's mediation. Prince Rupprecht warned Prince Max of Baden "Our military situation has deteriorated so rapidly that I no longer believe we can hold out over the winter; it is even possible that a catastrophe will come earlier." On 10 September Hindenburg urged peace moves to Emperor Charles of Austria and Germany appealed to Holland for mediation. On the 14th Austria sent a note to all belligerents and neutrals suggesting a meeting for peace talks on neutral soil and on 15 September Germany made a peace offer to Belgium. Both peace offers were rejected and on 24 September OHL informed the leaders in Berlin that armistice talks were inevitable.[67]
September saw the Germans continuing to fight strong rear guard actions and launching numerous counter attacks on lost positions, with only a few succeeding and then only temporarily. Contested towns, villages, heights and trenches in the screening positions and outposts of the Hindenburg Line continued to fall to the Allies as well as thousands of prisoners, with the BEF alone taking 30,441 in the last week of September. Further small advances eastward would follow the Third Army victory at Ivincourt on 12 September, the Fourth Armies at Epheny on the 18th and the French gain of Essigny Le Grand a day later. On the 24th a final assault by both the British and French on a four mile (6 km) front would come within two miles (3 km) of St. Quentin.[67] With the outposts and preliminary defensive lines of the Siegfried and Alberich Positions eliminated the Germans were now completely back in the Hindenburg line. With the Wotan position of that line already breached and the Siegfried position in danger of being turned from the north the time had now come for an assault on the whole length of the line.
The Allied attack on the Hindenburg Line began on 26 September. 260,000 U.S. soldiers went "over the top". All initial objectives were captured; the U.S. 79th Infantry Division, which met stiff resistance at Montfaucon, took an extra day to capture its objective. The U.S. Army stalled due to supply problems because its inexperienced headquarters had to cope with large units and a difficult landscape.[70] At the same time, French units broke through in Champagne and
