The Allies of World War I or Entente Powers was the coalition that opposed the Central Powers of Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria during the First World War (1914–1918).

The term "coalition" is the denotation for a group formed when two or more people, factions, states, political parties, militaries etc. agree to work together temporarily in a partnership to achieve a common goal. The word coalition connotes a coming together to achieve a goal.

Central Powers group of countries defeated in World War I

The Central Powers, consisting of Germany, Austria-Hungary, the Ottoman Empire and Bulgaria—hence also known as the Quadruple Alliance —was one of the two main coalitions that fought World War I (1914–18).

German Empire empire in Central Europe between 1871–1918

The German Empire, also known as Imperial Germany, was the German nation state that existed from the unification of Germany in 1871 until the abdication of Kaiser Wilhelm II in 1918.

By the end of the first decade of the 20th century, the major European powers were divided between the Triple Entente and the Triple Alliance. The Entente was made up of France, the United Kingdom and Russia. The Triple Alliance was originally composed of Germany, Austria-Hungary and Italy, which remained neutral in 1914.

Triple Entente early 20th century alliance between France, Russia and the United Kingdom

The Triple Entente refers to the understanding linking the Russian Empire, the French Third Republic, and the United Kingdom of Great Britain and Ireland after the signing of the Anglo-Russian Entente on 31 August 1907. The understanding between the three powers, supplemented by agreements with Japan and Portugal, was a powerful counterweight to the Triple Alliance of Germany, Austria-Hungary, and Italy.

Triple Alliance (1882) 1882 alliance between Germany, Austria–Hungary, Italy, and Romania

The Triple Alliance was an agreement between Germany, Austria-Hungary, and Italy. It was formed on 20 May 1882 and renewed periodically until it expired in 1915 during World War I. Germany and Austria-Hungary had been closely allied since 1879. Italy was looking for support against France shortly after it lost North African ambitions to the French. Each member promised mutual support in the event of an attack by any other great power. The treaty provided that Germany and Austria-Hungary were to assist Italy if it was attacked by France without provocation. In turn, Italy would assist Germany if attacked by France. In the event of a war between Austria-Hungary and Russia, Italy promised to remain neutral. The existence and membership of the treaty were well known, but its exact provisions were kept secret until 1919.

French Third Republic Nation of France from 1870 to 1940

The French Third Republic was the system of government adopted in France from 1870, when the Second French Empire collapsed during the Franco-Prussian War, until 10 July 1940 after France's defeat by Nazi Germany in World War II led to the formation of the Vichy government in France.

As the war progressed, each coalition added new members. Japan joined the Entente in 1914. After proclaiming its neutrality at the beginning of the war, Italy also joined the Entente in 1915. The United States joined as an "associated power" rather than an official ally. 'Associated members' included Serbia, Belgium, Greece, Montenegro, and Romania. [1]

Empire of Japan Empire in the Asia-Pacific region between 1868–1947

The Empire of Japan was the historical nation-state and great power that existed from the Meiji Restoration in 1868 to the enactment of the 1947 constitution of modern Japan.

United States Federal republic in North America

The United States of America (USA), commonly known as the United States or America, is a country comprising 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is slightly smaller than the entire continent of Europe's 3.9 million square miles. With a population of more than 327 million people, the U.S. is the third most populous country. The capital is Washington, D.C., and the most populous city is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico. The State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean. The U.S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The extremely diverse geography, climate, and wildlife of the United States make it one of the world's 17 megadiverse countries.

Kingdom of Serbia 1882-1918 kingdom in Southeastern Europe

The Kingdom of Serbia was created when Milan I, ruler of the Principality of Serbia, was proclaimed king in 1882.

When the war began in 1914, the Central Powers were opposed by the Triple Entente, formed in 1907 by the British Empire, the Russian Empire and the French Third Republic.

British Empire States and dominions ruled by the United Kingdom

The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom and its predecessor states. It originated with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. At its height, it was the largest empire in history and, for over a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, 23% of the world population at the time, and by 1920, it covered 35,500,000 km2 (13,700,000 sq mi), 24% of the Earth's total land area. As a result, its political, legal, linguistic and cultural legacy is widespread. At the peak of its power, the phrase "the empire on which the sun never sets" was often used to describe the British Empire, because its expanse around the globe meant that the sun was always shining on at least one of its territories.

Russian Empire former country, 1721–1917

The Russian Empire was an empire that extended across Eurasia and North America from 1721, following the end of the Great Northern War, until the Republic was proclaimed by the Provisional Government that took power after the February Revolution of 1917.

Fighting commenced when Austria invaded Serbia on 28 July 1914, purportedly in response to the assassination of Archduke Franz Ferdinand, heir to Emperor Franz Joseph; this brought Serbia's ally Montenegro into the war on 8 August and it attacked the Austrian naval base at Cattaro, modern Kotor. [2] At the same time, German troops entered neutral Belgium and Luxembourg as dictated by the Schlieffen Plan; over 95% of Belgium was occupied but the Belgian Army held their lines on the Yser Front throughout the war. This allowed Belgium to be treated as an Ally, in contrast to Luxembourg which retained control over domestic affairs but was occupied by the German military.

Assassination of Archduke Franz Ferdinand an assassination that occurred in Sarajevo on 28 June 1914

The assassination of Archduke Franz Ferdinand of Austria, heir presumptive to the Austro-Hungarian throne, and Franz Ferdinand's wife Sophie, Duchess of Hohenberg, occurred on 28 June 1914 in Sarajevo when they were mortally wounded by Gavrilo Princip. Princip was one of a group of six assassins coordinated by Danilo Ilić, a Bosnian Serb and a member of the Black Hand secret society. The political objective of the assassination was to break off Austria-Hungary's South Slav provinces so they could be combined into a Yugoslavia. The conspirators' motives were consistent with the movement that later became known as Young Bosnia. The assassination led directly to World War I when Austria-Hungary subsequently issued an ultimatum to the Kingdom of Serbia, which was partially rejected. Austria-Hungary then declared war on Serbia, triggering actions leading to war between most European states.

Franz Joseph I of Austria Emperor of Austria and King of Hungary

Franz Joseph I or Francis Joseph I was Emperor of Austria, King of Hungary, King of Bohemia, and monarch of many other states of the Austro-Hungarian Empire, from 2 December 1848 to his death. From 1 May 1850 to 24 August 1866 he was also President of the German Confederation. He was the longest-reigning Emperor of Austria and King of Hungary, as well as the third-longest-reigning monarch of any country in European history, after Louis XIV of France and Johann II of Liechtenstein.

Kingdom of Montenegro 1910-1918 kingdom in Southeastern Europe

The Kingdom of Montenegro was a monarchy in southeastern Europe, present-day Montenegro, during the tumultuous years on the Balkan Peninsula leading up to and during World War I. Legally it was a constitutional monarchy, but absolutist in practice. On 28 November 1918, following the end of World War I, with the Montenegrin government still in exile, the Podgorica Assembly proclaimed unification with the Kingdom of Serbia which itself was merged into the Kingdom of Serbs, Croats and Slovenes three days later, on 1 December 1918.

In the East, between 7–9 August the Russians entered German East Prussia on 7 August, Austrian Eastern Galicia. Japan joined the Entente by declaring war on Germany on 23 August, then Austria on 25 August. [3] On 2 September, Japanese forces surrounded the German Treaty Port of Tsingtao (now Qingdao) in China and occupied German colonies in the Pacific, including the Mariana, Caroline, and Marshall Islands.

Russian invasion of East Prussia (1914) battle

The Russian invasion of East Prussia occurred during World War I, lasting from August to September 1914. As well as being the natural course for the Russian Empire to take upon the declaration of war on the German Empire, it was also an attempt to focus the German Army on the Eastern Front, as opposed to the Western Front. Despite having an overwhelming superiority over the Germans in numbers, the invading Imperial Russian Army spread its forces thin and was defeated in the battles of Tannenberg and the Masurian Lakes. It was the only time that Germany was ever invaded in World War I.

On August 18, 1914, the Imperial Russian Army invaded the Austrian Crownland of Galicia. On August 19, Russian troops defeated the Austro-Hungarian Army, advanced 280–300 kilometers into Austrian territory and captured most of eastern Galicia. The principal city, Lemberg, fell into Russian hands on September 3. Eastern Galicia had a population of approximately 4.8 million people

Treaty ports Ports in East Asia opened to trade with Western countries

The treaty ports refers to the port cities in China and Japan that were opened to foreign trade mainly by the so-called "unequal treaties" with the Western powers, as well as cities in Korea opened up in similar fashion by the Japanese Empire.

Despite its membership of the Triple Alliance, Italy remained neutral until 23 May 1915 when it joined the Entente, declaring war on Austria but not Germany. On 17 January 1916, Montenegro capitulated and left the Entente; [4] this was offset when Germany declared war on Portugal in March 1916, while Romania commenced hostilities against Austria on 27 August. [5]

On 6 April 1917, the United States entered the war as a co-belligerent, along with the associated allies of Liberia, Siam and Greece. After the 1917 October Revolution, Russia left the Entente and agreed to a separate peace with the Central Powers with the signing of the Treaty of Brest-Litovsk on 3 March 1918. Romania was forced to do the same in the May 1918 Treaty of Bucharest but on 10 November, it repudiated the Treaty and once more declared war on the Central Powers.

These changes meant the Allies who negotiated the Treaty of Versailles in 1919 included France, Britain, Italy, Japan and the US; Part One of the Treaty agreed to the establishment of the League of Nations on 25 January 1919. [6] This came into being on 16 January 1920 with Britain, France, Italy and Japan as permanent members of the Executive Council; the US Senate voted against ratification of the Treaty of Versailles on 19 March, thus preventing American participation.

Principal powers

British Empire

For much of the 19th century, Britain sought to maintain the European balance of power without formal alliances, a policy known as splendid isolation. This left it dangerously exposed as Europe divided into opposing power blocs and the 1895–1905 Conservative government negotiated first the 1902 Anglo-Japanese Alliance, then the 1904 Entente Cordiale with France. [16] The first tangible result of this shift was British support for France against Germany in the 1905 Moroccan Crisis.

The 1905–1915 Liberal government continued this re-alignment with the 1907 Anglo-Russian Convention. Like the Anglo-Japanese and Entente agreements, it focused on settling colonial disputes but by doing so paved the way for wider co-operation and allowed Britain to refocus resources in response to German naval expansion. [17]

Since control of Belgium allowed an opponent to threaten invasion or blockade British trade, preventing it was a long-standing British strategic interest. [lower-alpha 4] [18] Under Article VII of the 1839 Treaty of London, Britain guaranteed Belgian neutrality against aggression by any other state, by force if required. [19] Chancellor Bethmann Hollweg later dismissed this as a 'scrap of paper,' but British law officers routinely confirmed it as a binding legal obligation and its importance was well understood by Germany. [20]

The 1911 Agadir Crisis led to secret discussions between France and Britain in case of war with Germany. These agreed that within two weeks of its outbreak, a British Expeditionary Force of 100,000 men would be landed in France; in addition, the Royal Navy would be responsible for the North Sea, the Channel and protecting Northern France, with the French navy concentrated in the Mediterranean. [21] Britain was committed to support France in a war against Germany but this was not widely understood outside government or the upper ranks of the military.

As late as 1 August, a clear majority of the Liberal government and its supporters wanted to stay out of the war. [22] While Liberal leaders H. H. Asquith and Edward Grey considered Britain legally and morally committed to support France regardless, waiting until Germany triggered the 1839 Treaty provided the best chance of preserving Liberal party unity. [23]

The German high command was aware entering Belgium would lead to British intervention but decided the risk was acceptable; they expected a short war while their ambassador in London claimed troubles in Ireland would prevent Britain from assisting France. [24] On 3 August, Germany demanded unimpeded progress through any part of Belgium and when this was refused, invaded early on the morning of 4 August.

This changed the situation; the invasion of Belgium consolidated political and public support for the war by presenting what appeared to be a simple moral and strategic choice. [25] The Belgians asked for assistance under the 1839 Treaty and in response, Britain declared war on Germany on 4 August 1914. [26] Although Germany's violation of Belgium neutrality was not the only cause of British entry into the war, it was used extensively in government propaganda at home and abroad to make the case for British intervention. [27] This confusion arguably persists today.

The declaration of war automatically involved all dominions and colonies and protectorates of the British Empire, many of whom made significant contributions to the Allied war effort, both in the provision of troops and civilian labourers. It was split into Crown Colonies administered by the Colonial Office in London, such as Nigeria, [lower-alpha 5] and the self-governing Dominions of Canada, Newfoundland, New Zealand, Australia and South Africa. These controlled their own domestic policies and military expenditure but not foreign policy.

In terms of population, the largest component (after Britain herself) was the British Raj or British India, which included modern India, Pakistan, Myanmar and Bangladesh. Unlike other colonies which came under the Colonial Office, it was governed directly by the India Office or by princes loyal to the British; it also controlled British interests in the Persian Gulf, such as the Trucial States and Oman. Over one million soldiers of the British Indian Army served in different theatres of the war, primarily France and the Middle East.

From 1914–1916, overall Imperial diplomatic, political and military strategy was controlled by the British War Cabinet in London; in 1917 it was superseded by the Imperial War Cabinet, which included representatives from the Dominions. [28] Under the War Cabinet were the Chief of the Imperial General Staff or CIGS, responsible for all Imperial ground forces, and the Admiralty that did the same for the Royal Navy. Theatre commanders like Douglas Haig on the Western Front or Edmund Allenby in Palestine then reported to the CIGS.

After the Indian Army, the largest individual units were the Australian Corps and Canadian Corps in France, which by 1918 were commanded by their own generals, John Monash and Arthur Currie. [29] Contingents from South Africa, New Zealand and Newfoundland served in theatres including France, Gallipoli, German East Africa and the Middle East. Australian troops separately occupied German New Guinea, with the South Africans doing the same in German South West Africa; this resulted in the Maritz rebellion by former Boers, which was quickly suppressed. After the war, New Guinea and South-West Africa became Protectorates, held until 1975 and 1990 respectively.

Russian Empire

Between 1873–1887, Russia was allied with Germany and Austria-Hungary in the League of the Three Emperors, then with Germany in the 1887–1890 Reinsurance Treaty; both collapsed due to the competing interests of Austria and Russia in the Balkans. While France took advantage of this to agree the 1894 Franco-Russian Alliance, Britain viewed Russia with deep suspicion; in 1800, over 3,000 kilometres separated the Russian Empire and British India, by 1902, it was 30 km in some areas. [30] This threatened to bring the two into direct conflict, as did the long-held Russian objective of gaining control of the Bosporus Straits and with it access to the British-dominated Mediterranean Sea. [31]

Defeat in the 1905 Russo-Japanese War and Britain's isolation during the 1899–1902 Second Boer War led both parties to seek allies. The Anglo-Russian Convention of 1907 settled disputes in Asia and allowed the establishment of the Triple Entente with France, which at this stage was largely informal. In 1908, Austria annexed the former Ottoman province of Bosnia and Herzegovina; Russia responded by creating the Balkan League in order to prevent further Austrian expansion. [32] In the 1912-1913 First Balkan War, Serbia, Bulgaria and Greece captured most of the remaining Ottoman possessions in Europe; disputes over the division of these resulted in the Second Balkan War, in which Bulgaria was comprehensively defeated by its former allies.

Russia's industrial base and railway network had significantly improved since 1905, although from a relatively low base; in 1913, Tsar Nicholas approved an increase in the Russian Army of over 500,000 men. Although there was no formal alliance between Russia and Serbia, their close bilateral links provided Russia with a route into the crumbling Ottoman Empire, where Germany also had significant interests. Combined with the increase in Russian military strength, both Austria and Germany felt threatened by Serbian expansion; when Austria invaded Serbia on 28 July 1914, Russian Foreign Minister Sergey Sazonov viewed it as an Austro-German conspiracy to end Russian influence in the Balkans. [33]

In addition to its own territory, Russia viewed itself as the defender of its fellow Slavs and on 30 July, mobilised in support of Serbia. In response, Germany declared war on Russia on 1 August, followed by Austria-Hungary on 6th; after Ottoman warships bombarded Odessa in late October, the Entente declared war on the Ottoman Empire in November 1914. [34]

French Republic

French defeat in the 1870–1871 Franco-Prussian War led to the loss of the two provinces of Alsace-Lorraine and the establishment of the Third Republic. The suppression of the Paris Commune by the new regime caused deep political divisions and led to a series of bitter political struggles, such as the Dreyfus affair. As a result, aggressive nationalism or Revanchism was one of the few areas to unite the French.

The loss of Alsace-Lorraine deprived France of its natural defence line on the Rhine, while it was weaker demographically than Germany, whose 1911 population was 64.9 million to 39.6 in France, which had the lowest birthrate in Europe. [35] This meant that despite their very different political systems, when Germany allowed the Reinsurance Treaty to lapse, France seized the opportunity to agree the 1894 Franco-Russian Alliance. It also replaced Germany as the primary source of financing for Russian industry and the expansion of its railway network, particularly in border areas with Germany and Austria-Hungary. [36]

However, Russian defeat in the 1904–1905 Russo-Japanese War damaged its credibility, while Britain's isolation during the Second Boer War meant both countries sought additional allies. This resulted in the 1904 Entente Cordiale with Britain; like the 1907 Anglo-Russian Convention, for domestic British consumption it focused on settling colonial disputes but led to informal co-operation in other areas. By 1914, both the British army and Royal Navy were committed to support France in the event of war with Germany but even in the British government, very few were aware of the extent of these commitments. [37]

In response to Germany's declaration of war on Russia, France issued a general mobilization in expectation of war on 2 August and on 3 August, Germany also declared war on France. [38] Germany's ultimatum to Belgium brought Britain into the war on 4 August, although France did not declare war on Austria-Hungary until 12 August.

As with Britain, France's colonies also became part of the war; pre-1914, French soldiers and politicians advocated using French African recruits to help compensate for France's demographic weakness. [39] From August to December 1914, the French lost nearly 300,000 dead on the Western Front, more than Britain suffered in the whole of WWII and the gaps were partly filled by colonial troops, over 500,000 of whom served on the Western Front over the period 1914–1918. [40] Colonial troops also fought at Gallipoli, occupied Togo and Kamerun in West Africa and had a minor role in the Middle East, where France was the traditional protector of Christians in the Ottoman provinces of Syria, Palestine and Lebanon. [41]

Empire of Japan

Prior to the Meiji Restoration in 1868, Japan was a semi-feudal, largely agrarian state with few natural resources and limited technology. By 1914, it had transformed itself into a modern industrial state, with a powerful military; by defeating China in the First Sino-Japanese War in 1894–1895, it established itself as the primary power in East Asia and colonized the then-unified Korea and Formosa, now modern Taiwan.

Concerned by Russian expansion in Korea and Manchuria, Britain and Japan signed the Anglo-Japanese Alliance on 30 January 1902, agreeing if either were attacked by a third party, the other would remain neutral and if attacked by two or more opponents, the other would come to its aid. This meant Japan could rely on British support in a war with Russia, if either France or Germany, which also had interests in China, decided to join them. [42] This gave Japan the reassurance needed to take on Russia in the 1905 Russo-Japanese War; victory established Japan in the Chinese province of Manchuria.

With Japan as an ally in the Far East, John Fisher, First Sea Lord from 1904–1910, was able to refocus British naval resources in the North Sea to counter the threat from the Imperial German Navy. The Alliance was renewed in 1911; in 1914, Japan joined the Entente in return for German territories in the Pacific, greatly annoying the Australian government which also wanted them. [43]

On 7 August, Britain officially asked for assistance in destroying German naval units in China and Japan formally declared war on Germany on 23 August, followed by Austria-Hungary on 25th. [44] On 2 September 1914, Japanese forces surrounded the German Treaty Port of Qingdao, then known as Tsingtao, which surrendered on 7 November. The Imperial Japanese Navy simultaneously occupied German colonies in the Mariana, Caroline, and Marshall Islands, while in 1917, a Japanese naval squadron was sent to support the Allies in the Mediterranean. [45]

Japan's primary interest was in China and in January 1915, the Chinese government was presented with a secret ultimatum of Twenty-One Demands, demanding extensive economic and political concessions. While these were eventually modified, the result was a surge of anti-Japanese nationalism in China and an economic boycott of Japanese goods. [46] In addition, the other Allies now saw Japan as a threat, rather than a partner, lead to tensions first with Russia, then the US after it entered the war in April 1917. Despite protests from the other Allies, after the war Japan refused to return Qingdao and the province of Shandong to China. [47]

The 1882 Triple Alliance between Germany, Austria-Hungary and Italy was renewed at regular intervals, but was compromised by conflicting objectives between Italy and Austria in the Adriatic and Aegean seas. Italian nationalists referred to Austrian-held Trieste and South Tyrol as 'the lost territories,' making the Alliance so controversial that the terms were kept secret until it expired in 1915. [48]

Alberto Pollio, the pro-Austrian Chief of Staff of the Italian Army, died on 1 July 1914, taking many of the prospects for Italian support with him. [49] The Italian Prime Minister Antonio Salandra argued that as the Alliance was defensive in nature, Austria's aggression against Serbia and Italy's exclusion from the decision-making process meant it was not obliged to join them. [50]

His caution was understandable because France and Britain either supplied or controlled the import of most of Italy's raw materials, including 90% of its coal. [50] Salandra described the process of choosing a side as 'sacred egoism,' but as the war was expected to end before mid-1915 at the latest, making this decision became increasingly urgent. [51] In line with Italy's obligations under the Triple Alliance, the bulk of the army was concentrated on Italy's border with France; in October, Pollio's replacement, General Luigi Cadorna, was ordered to begin moving these troops to the North-Eastern one with Austria. [52]

Under the April 1915 Treaty of London, Italy agreed to join the Entente in return for Italian-populated territories of Austria-Hungary and other concessions; in return, it declared war on Austria-Hungary in May 1915 as required, although not on Germany until 1916. [53] Italian resentment at the difference between the promises of 1915 and the actual results of the 1919 Treaty of Versailles would be powerful factors in the rise of Mussolini. [54]

Affiliated state combatants

Kingdom of Serbia

In 1817, the Principality of Serbia became an autonomous province within the Ottoman Empire; with Russian support, it gained full independence after the 1877–1878 Russo-Turkish War. Many Serbs viewed Russia as protector of the South Slavs in general but also specifically against Bulgaria, where Russian objectives increasingly collided with Bulgarian nationalism. [55]

When Austria annexed Bosnia and Herzegovina in 1908, Russia responded by creating the Balkan League to prevent further Austrian expansion. [56] Austria viewed Serbia with hostility partly due to its links with Russia, whose claim to be the protector of South Slavs extended to those within the Austro-Hungarian empire, such as the Czechs and Slovaks. Serbia also potentially gave Russia the ability to achieve their long-held objective of capturing Constantinople and the Dardanelles. [31]

Austria backed the Albanian revolt of 1910 and the idea of a Greater Albania, since this would prevent Serbian access to the Austrian-controlled Adriatic Sea. [57] Another Albanian revolt in 1912 exposed the weakness of the Ottoman Empire and led to the 1912-1913 First Balkan War, with Serbia, Montenegro, Bulgaria and Greece capturing most of the remaining Ottoman possessions in Europe. Disputes over the division of these resulted in the Second Balkan War, in which Bulgaria was comprehensively defeated by its former allies.

As a result of the 1913 Treaty of Bucharest, Serbia increased its territory by 100% and its population by 64%. [58] However, it now faced a hostile Austria-Hungary, a resentful Bulgaria and opposition by Albanian nationalists. Germany too had ambitions in the Ottoman Empire, the centrepiece being the planned Berlin–Baghdad railway, with Serbia the only section not controlled by a pro-German state.

The exact role played by Serbian officials in the assassination of Archduke Franz Ferdinand is still debated but despite complying with most of their demands, Austria-Hungary invaded on 28 July 1914. While Serbia successfully repulsed the Austro-Hungarian army in 1914, it was exhausted by the two Balkan Wars and unable to replace its losses of men and equipment. In 1915, Bulgaria joined the Central Powers and by the end of the year, a combined Bulgar-Austrian-German army occupied most of Serbia. Between 1914–1918, Serbia suffered the greatest proportional losses of any combatant, with over 25% of all those mobilised becoming casualties; including civilians and deaths from disease, over 1.2 million died, nearly 30% of the entire population.

Kingdom of Belgium

In 1830, the southern provinces of the Netherlands broke away to form the Kingdom of Belgium and their independence was confirmed by the 1839 Treaty of London. Article VII of the Treaty required Belgium to remain perpetually neutral and committed Austria, France, Germany and Russia to guarantee that against aggression by any other state, including the signatories. [59]

While the French and German militaries accepted Germany would almost certainly violate Belgian neutrality in the event of war, the extent of that was unclear. The original Schlieffen Plan only required a limited incursion into the Belgian Ardennes, rather than a full-scale invasion; in September 1911, the Belgian Foreign Minister told a British Embassy official they would not call for assistance if the Germans limited themselves to that. [60] While neither Britain or France could allow Germany to occupy Belgium unopposed, a Belgian refusal to ask for help would complicate matters for the British Liberal government, which contained a significant isolationist element.

However, the key German objective was to avoid war on two fronts; France had to be defeated before Russia could fully mobilise and give time for German forces to be transferred to the East. The growth of the Russian railway network and increase in speed of mobilisation made rapid victory over France even more important; to accommodate the additional 170,000 troops approved by the 1913 Army Bill, the 'incursion' now became a full-scale invasion. The Germans accepted the risk of British intervention; in common with most of Europe, they expected it to be a short war while their London Ambassador claimed civil war in Ireland would prevent Britain from assisting its Entente partners. [61]

On 3 August, a German ultimatum demanded unimpeded progress through any part of Belgium, which was refused. Early on the morning of 4 August, the Germans invaded and the Belgian government called for British assistance under the 1839 Treaty; by the end of 1914, over 95% of the country was occupied but the Belgian Army held their lines on the Yser Front throughout the war.

In the Belgian Congo, 25,000 Congolese troops plus an estimated 260,000 porters joined British forces in the 1916 East African Campaign. [62] By 1917, they controlled the western part of German East Africa which would become the Belgian League of Nations Mandate of Ruanda-Urundi or modern-day Rwanda and Burundi. [63]

Republic of the United States of Brazil

Brazil entered the war in 1917 after the United States intervened on the basis of Germany's unrestricted submarine warfare sinking its merchant ships, which Brazil also cited as a reason to enter the war fighting against Germany and the Central Powers. The First Brazilian Republic sent the Naval Division in War Operations that joined the British fleet in Gibraltar and made the first Brazilian naval effort in international waters. In compliance with the commitments made at the Inter-American Conference, held in Paris from 20 November to 3 December 1917, the Brazilian Government sent a medical mission composed of civilian and military surgeons to work in field hospitals of the European theater, a contingent of sergeants and officers to serve with the French army; Airmen from the Army and Navy to join the Royal Air Force, and the employment of part of the Fleet, primarily in the anti-submarine war.

Greece almost doubled in size as a result of the Balkan Wars of 1912 and 1913, but success masked deep divisions within the political elite. In 1908, the island of Crete, formally part of the Ottoman Empire but administered by Greek officials, declared union with Greece, led by the charismatic nationalist Eleftherios Venizelos. A year later, young army officers formed the Military League to advocate for an aggressive and expansionist foreign policy; with their backing, Venizelos won a majority in the 1910 Parliamentary elections, followed by another in 1912. [64] He had effectively broken the power of the pre-1910 political class and his position was then further strengthened by success in the Balkan Wars.

In 1913, the Greek monarch George I was assassinated; he was succeeded by his son Constantine who had attended Heidelberg University, served in a Prussian regiment and married Sophia of Prussia, sister of Emperor William II. These links and a belief the Central Powers would win the war combined to make Constantine pro-German. [65] Venizelos himself favoured the Entente, partly due to their ability to block the maritime trade routes required for Greek imports.

Other issues adding complexity to this decision included disputes with Bulgaria and Serbia over the regions of Thrace and Macedonia as well as control of the Aegean Islands. Greece captured most of the islands during the Balkan Wars but Italy occupied the Dodecanese in 1912 and was in no hurry to give them back, while the Ottomans demanded the return of many others. [66] In general, the Triple Entente favoured Greece, the Triple Alliance backed the Ottomans; Greece ultimately gained the vast majority but Italy did not cede the Dodecanese until 1947, while others remain disputed even today.

As a result, Greece initially remained neutral but in March 1915, the Entente offered concessions to join the Dardanelles campaign. Arguments over whether to accept led to the National Schism, with an Entente-backed administration under Venizelos in Crete, and a Royalist one led by Constantine in Athens that supported the Central Powers. [65]

In September 1915, Bulgaria joined the Central Powers; in October, Venizelos allowed Entente forces to land at Thessaloniki or Salonica to support the Serbs, although they were too late to prevent their defeat. In August 1916, Bulgarian troops advanced into Greek-held Macedonia and Constantine ordered the army not to resist; anger at this led to a coup and he was eventually forced into exile in June 1917. A new national government under Venizelos joined the Entente, while the Greek National Defence Army Corps fought with the Allies on the Macedonian Front.

Kingdom of Montenegro

Nicholas accepts the surrender of Scutari, April 1913; Montenegro's major gain from the Balkan War, it was relinquished several months later.

Unlike Serbia, with whom it shared close cultural and political connections, the Kingdom of Montenegro gained little from its participation in the 1912–1913 Balkan Wars. The main Montenegrin offensive was in Ottoman-controlled Albania, where it suffered heavy losses during the seven month Siege of Scutari. Austria-Hungary opposed Serb or Montenegrin control of Albania, since it provided access to the Adriatic Sea; despite Scutari's surrender, Montenegro was forced to relinquish it by the 1913 Treaty of London and it became capital of the short-lived Principality of Albania. [67] This was largely an Austrian creation; the new ruler, William, Prince of Albania, was a German who was forced into exile in September, only seven months after taking up his new position and later served with the Austrian army.

In addition to the lack of substantive gains from the Balkan Wars, there were long-running internal divisions between those who like Nicholas I preferred an independent Montenegro and those who advocated union with Serbia. In July 1914, Montenegro was not only militarily and economically exhausted, but also faced a multitude of political, economic and social issues. [68]

At meetings held in March 1914, Austria-Hungary and Germany agreed union with Serbia must be prevented; Montenegro could either remain independent or be divided, its coastal areas becoming part of Albania, while the rest could join Serbia. [68]

Nicholas seriously considered neutrality as a way to preserve his dynasty and on 31 July notified the Russian Ambassador Montenegro would only respond to an Austrian attack. He also held discussions with Austria, proposing neutrality or even active support in return for territorial concessions in Albania. [69]

However, close links between the Serbian and Montenegrin militaries as well as popular sentiment meant there was little support for remaining neutral, especially after Russia joined the war; on 1 August, the National Assembly declared war on Austria-Hungary in fulfilment of its obligations to Serbia. After some initial success, in January 1916, the Montenegrin Army was forced to surrender to an Austro-Hungarian force.

Emirate of Nejd and Hasa

The Emirate of Nejd and Hasa agreed to enter the war as an ally of Britain in the Treaty of Darin on 26 December 1915. [70]

Idrisid Emirate of Asir

The Idrisid Emirate of Asir participated in the Arab revolt. Its Emir, Muhammad ibn Ali al-Idrisi, signed an agreement with the British and joined the Allies in May 1915.

Equal status with the main Allied Powers was one of the primary conditions for Romania's entry into the War. The Powers officially recognized this status through the 1916 Treaty of Bucharest. [71] Romania fought on three of the four European Fronts: Eastern, Balkan and Italian, fielding in total over 1,200,000 troops. [72]

Romanian military industry was mainly focused on converting various fortification guns into field and anti-aircraft artillery. Up to 334 German 53 mm Fahrpanzer guns, 93 French 57 mm Hotchkiss guns, 66 Krupp 150 mm guns, and dozens more 210 mm guns were mounted on Romanian-built carriages and transformed into mobile field artillery, with 45 Krupp 75 mm guns and 132 Hotchkiss 57 mm guns being transformed into anti-aircraft artillery. The Romanians also upgraded 120 German Krupp 105 mm howitzers, the result being the most effective field howitzer in Europe at that time. Romania even managed to design and build from scratch its own model of mortar, the 250 mm Negrei Model 1916. [73]

Other Romanian technological assets include the building of Vlaicu III, the world's first aircraft made of metal. [74] The Romanian Navy possessed the largest warships on the Danube. They were a class of four river monitors, built locally at the Galați shipyard using parts manufactured in Austria-Hungary. The first one launched was Lascăr Catargiu, in 1907. [75] [76] The Romanian monitors displaced almost 700 tons, were armed with three 120 mm naval guns in three turrets, two 120 mm naval howitzers, four 47 mm anti-aircraft guns and two 6.5 machine guns. [77] The monitors took part in the Battle of Turtucaia and the First Battle of Cobadin. The Romanian-designed Schneider 150 mm Model 1912 howitzer was considered one of the most modern field guns on the Western Front. [78]

Romania's entry into the War in August 1916 provoked major changes for the Germans. General Erich von Falkenhayn was dismissed and sent to command the Central Powers forces in Romania, which enabled Hindenburg's subsequent ascension to power. [79] Due to having to fight against all of the Central Powers on the longest front in Europe (1,600 km) and with little foreign help (only 50,000 Russians aided 650,000 Romanians in 1916), [80] the Romanian capital was conquered that December. Vlaicu III was also captured and shipped to Germany, being last seen in 1942. [81] The Romanian administration established a new capital at Iași and continued to fight on the Allied side in 1917. [82] Despite being relatively short, the Romanian campaign of 1916 provided considerable respite for the Western Allies, as the Germans ceased all their other offensive operations in order to deal with Romania. [83] After suffering a tactical defeat against the Romanians (aided by Russians) in July 1917 at Mărăști, the Central Powers launched two counterattacks, at Mărășești and Oituz. The German offensive at Mărășești was soundly defeated, with German prisoners later telling their Romanian captors that German casualties were extremely heavy, and that they "had not encountered such stiff resistance since the battles of Somme and Verdun". [84] The Austro-Hungarian offensive at Oituz also failed. On 22 September, the Austro-Hungarian Enns-class river monitor SMS Inn was sunk by a Romanian mine near Brăila. [85] [86] After Russia signed the Treaty of Brest-Litovsk and dropped out of the War, Romania was left surrounded by the Central Powers and eventually signed a similar treaty on 7 May 1918. Despite being forced to cede land to Austria-Hungary and Bulgaria, Romania ended up with a net gain in territory due to the Union with Bessarabia. On 10 November, Romania re-entered the War and fought a war with Hungary that lasted until August 1919.

Co-belligerents; the United States

The United States declared war on Germany in April 1917 on the grounds that Germany violated US neutrality by attacking international shipping with its unrestricted submarine warfare campaign. [87] The remotely connected Zimmermann Telegram of the same period, within which the Germans promised to help Mexico regain some of its territory lost to the U.S nearly seven decades before in the event of the United States entering the war, was also a contributing factor. The US entered the war as an "associated power", rather than a formal ally of France and the United Kingdom, in order to avoid "foreign entanglements". [88] Although the Ottoman Empire and Bulgaria severed relations with the United States, neither declared war, [89] nor did Austria-Hungary. Eventually, however, the United States also declared war on Austria-Hungary in December 1917, predominantly to help hard-pressed Italy.

Non-state combatants

Eastern Front (World War I) Theatre of World War I

The Eastern Front or Eastern Theater of World War I was a theater of operations that encompassed at its greatest extent the entire frontier between the Russian Empire and Romania on one side and the Austro-Hungarian Empire, Bulgaria, the Ottoman Empire and the German Empire on the other. It stretched from the Baltic Sea in the north to the Black Sea in the south, involved most of Eastern Europe and stretched deep into Central Europe as well. The term contrasts with "Western Front", which was being fought in Belgium and France.

Balkans campaign (World War I) part of World War I

The Balkans campaign, or Balkan theatre of World War I was fought between the Central Powers, represented by Austria-Hungary, Bulgaria, Germany and the Ottoman Empire on one side and the Allies, represented by France, Montenegro, Russia, Serbia, and the United Kingdom on the other side.

Macedonian front part of the Balkans Theatre of WWI

The Macedonian front, also known as the Salonica front, was a military theatre of World War I formed as a result of an attempt by the Allied Powers to aid Serbia, in the fall of 1915, against the combined attack of Germany, Austria-Hungary and Bulgaria. The expedition came too late and in insufficient force to prevent the fall of Serbia, and was complicated by the internal political crisis in Greece. Eventually, a stable front was established, running from the Albanian Adriatic coast to the Struma River, pitting a multinational Allied force against the Bulgarian Army, which was at various times bolstered with smaller units from the other Central Powers. The Macedonian front remained quite stable, despite local actions, until the great Allied offensive in September 1918, which resulted in the capitulation of Bulgaria and the liberation of Serbia.

Union of Transylvania with Romania

The Union of Transylvania with Romania was declared on 1 December 1918 by the assembly of the delegates of ethnic Romanians held in Alba Iulia. The Great Union Day, celebrated on 1 December, is a national holiday in Romania that commemorates this event. The holiday was established after the Romanian Revolution, and commemorates the unification not only of Transylvania, but also of Bessarabia and Bukovina and parts of Banat, Crișana and Maramureș with the Romanian Kingdom. Bessarabia and Bukovina had joined with the Kingdom of Romania earlier in 1918.

Bulgaria during World War I aspect of history

The Kingdom of Bulgaria participated in World War I on the side of the Central Powers from 14 October 1915, when the country declared war on Serbia, until 30 September 1918, when the Armistice of Thessalonica came into effect.

The following outline is provided as an overview of and topical guide to World War I:

At the outbreak of World War I, Hungary was part of the dualist monarchy, Austria-Hungary. Although there are no significant battles specifically connected to Hungarian regiments, the troops suffered high losses throughout the war.

Allied leaders of World War I

The Allied leaders of World War I consist of the political and military figures that fought for or supported the Allies during World War I.

Henri Mathias Berthelot French general

Henri Mathias Berthelot (1861–1931) was a French general during World War I. He held an important staff position under Joseph Joffre, the French commander-in-chief, at the First Battle of the Marne, before later commanding a corps in the front line. In 1917 he helped to rebuild the Romanian Army following its disastrous defeat the previous autumn, then in summer 1918 he commanded French Fifth Army at the Second Battle of the Marne, with some British and Italian troops under his command. In the final days of the war he again returned to Romania, and then briefly commanded French intervention forces in southern Russia in the Russian Civil War.

Leaders of the Central Powers of World War I

The leaders of the Central Powers of World War I were the political or military figures who commanded or supported the Central Powers during World War I.

The Diplomatic history of World War I covers the non-military interactions among the major players during World War I. For the domestic histories see Home front during World War I. For a longer-term perspective see International relations of the Great Powers (1814–1919) and Causes of World War I. For the following era see International relations (1919–1939). The major allied players included Great Britain, France, Russia, and Italy and the United States. The major Central Powers included Germany and the Austria-Hungary, and the Ottoman Empire (Turkey). Other countries—and their colonies—were also involved. For a detailed chronology see Timeline of World War I.

As the French ambassador to Germany (1907-1914) Jules Cambon worked hard to secure a friendly détente. He was frustrated by French leaders such as Raymond Poincaré, who decided Berlin was trying to weaken the Triple Entente of France, Russia and Britain, and was not sincere in seeking peace. The French consensus was that war was inevitable.
