The Central Powers, also known as the Central Empires,[1][notes 1] were one of the two main coalitions that fought in World War I (1914–1918). It consisted of the German Empire, Austria-Hungary, the Ottoman Empire, and Bulgaria; this was also known as the Quadruple Alliance.[2][notes 2]

  • Sultan Mehmed V of the Ottoman Empire;

  • The caption reads:
  • "Vereinte Kräfte führen zum Ziel"
  • "United Powers Lead to the Goal"
  • The Central Powers' origin was the alliance of Germany and Austria-Hungary in 1879. Despite having nominally joined the Triple Alliance before, Italy did not take part in World War I on the side of the Central Powers. The Ottoman Empire and Bulgaria did not join until after World War I had begun. The Central Powers faced, and were defeated by, the Allied Powers, which themselves had formed around the Triple Entente.

    Member states

    At the start of the war, the Central Powers consisted of the German Empire and the Austro-Hungarian Empire. The Ottoman Empire joined later in 1914, followed by the Kingdom of Bulgaria in 1915. The name "Central Powers" is derived from the location of these countries; all four were located between the Russian Empire in the east and France and the United Kingdom in the west.

    In early July 1914, in the aftermath of the assassination of Austro-Hungarian

    general mobilization, Germany viewed the act as provocative.[4] The Russian government promised Germany that its general mobilization did not mean preparation for war with Germany but was a reaction to the tensions between Austria-Hungary and Serbia.[4] The German government regarded the Russian promise of no war with Germany to be nonsense in light of its general mobilization, and Germany, in turn, mobilized for war.[4] On 1 August, Germany sent an ultimatum to Russia stating that since both Germany and Russia were in a state of military mobilization, an effective state of war existed between the two countries.[5] Later that day, France, an ally of Russia, declared a state of general mobilization.[5]

    In August 1914, Germany attacked Russia, citing Russian aggression as demonstrated by the mobilization of the Russian army, which had resulted in Germany mobilizing in response.[6]

    After Germany declared war on Russia, France, with its alliance with Russia, prepared a general mobilization in expectation of war. On 3 August 1914, Germany responded to this action by declaring war on France.[7] Germany, facing a two-front war, enacted what was known as the Schlieffen Plan, which involved German armed forces moving through Belgium and swinging south into France and towards the French capital of Paris. This plan was hoped to quickly gain victory against the French and allow German forces to concentrate on the Eastern Front. Belgium was a neutral country and would not accept German forces crossing its territory. Germany disregarded Belgian neutrality and invaded the country to launch an offensive towards Paris. This caused Great Britain to declare war against the German Empire, as the action violated the Treaty of London that both nations signed in 1839 guaranteeing Belgian neutrality.

    Subsequently, several states declared war on Germany in late August 1914, with

    Greece
    in July 1917.

    Colonies and dependencies

    In Europe

    After successfully beating France in the Franco-Prussian War, the German Empire incorporated the province of Alsace-Lorraine upon its founding in 1871. However, the province was still claimed by French revanchists,[8][9] leading to its recession to France at the Treaty of Versailles.

    Africa

    The German Empire was late to colonization, only beginning overseas expansion in the 1870s and 1880s. Support for colonization was opposed by much of the government, including chancellor Otto von Bismarck, but it became a colonial power after participating in the Berlin Conference. Then, private companies were founded and began settling parts of Africa, the Pacific, and China. Later these groups became German protectorates and colonies.

    Cameroon was a German colony existing from 1884 until its complete occupation in 1915. It was ceded to France as a League of Nations Mandate at the war's end.

    German East Africa was founded in 1885 and expanded to include modern-day Tanzania (except Zanzibar), Rwanda, Burundi, and parts of Mozambique. It was the only German colony to not be fully conquered during the war, with resistance by commander Paul von Lettow-Vorbeck lasting until November 1918. Later it was surrendered to the Allies in 1919 and split between the Belgian Congo, Portuguese Mozambique, and the newly founded colony of Tanganyika.

    South West Africa, modern-day Namibia, became under German rule in 1885 and was absorbed into South Africa following its invasion in 1915. Members of the local German army and police fought with South Africans seeking independence in the Maritz Rebellion.

    Togoland, now part of Ghana, was made a German protectorate in 1884. However, after a swift campaign, it was occupied by the Allies in 1915 and divided between French Togoland and British Togoland.

    Asia

    The

    Jiaozhou Bay Leased Territory was a German dependency in East Asia leased from China in 1898. Japanese forces occupied it following the Siege of Tsingtao
    .

    Pacific

    German New Guinea was a German protectorate in the Pacific. It was occupied by Australian forces in 1914.

    German Samoa was a German protectorate following the Tripartite Convention. It was occupied by the New Zealand Expeditionary Force in 1914.

    Austria-Hungary

    War justifications

    Austria-Hungary regarded the assassination of

    Archduke Franz Ferdinand as having been orchestrated with the assistance of Serbia.[3] The country viewed the assassination as setting a dangerous precedent of encouraging the country's South Slav population to rebel and threaten to tear apart the multinational country.[4] Austria-Hungary sent a formal ultimatum to Serbia demanding a full-scale investigation of Serbian government complicity in the assassination and complete compliance by Serbia in agreeing to the terms demanded by Austria-Hungary.[3] Serbia submitted to accept most of the demands. However, Austria-Hungary viewed this as insufficient and used this lack of full compliance to justify military intervention.[10] These demands have been viewed as a diplomatic cover for an inevitable Austro-Hungarian declaration of war on Serbia.[10]

    Russia had warned Austria-Hungary that the Russian government would not tolerate Austria-Hungary invading Serbia.[10] However, with Germany supporting Austria-Hungary's actions, the Austro-Hungarian government hoped that Russia would not intervene and that the conflict with Serbia would remain a regional conflict.[3]

    Austria-Hungary's invasion of Serbia resulted in Russia declaring war on the country, and Germany, in turn, declared war on Russia, setting off the beginning of the clash of alliances that resulted in the World War.

    Territory

    Austria-Hungary was internally divided into two states with their own governments, joined through the Habsburg throne. Austria, also known as

    Bosnia and Herzegovina
    , sovereign authority was shared by both Austria and Hungary.

    Ottoman Empire

    War justifications

    The Ottoman Empire joined the war on the side of the Central Powers in November 1914. The Ottoman Empire had gained strong economic connections with Germany through the Berlin-to-Baghdad railway project that was still incomplete at the time.

    Bosphorus.[13] Ottoman officials informed the German government that the country needed time to prepare for conflict.[13] Germany provided financial aid and weapons shipments to the Ottoman Empire.[12]

    After pressure escalated from the German government demanding that the Ottoman Empire fulfill its treaty obligations, or else Germany would expel the country from the alliance and terminate economic and military assistance, the Ottoman government entered the war with the recently acquired cruisers from Germany, the Yavuz Sultan Selim (formerly SMS Goeben) and the Midilli (formerly SMS Breslau) launching a naval raid on the Russian port of Odesa, thus engaging in military action in accordance with its alliance obligations with Germany. Russia and the Triple Entente declared war on the Ottoman Empire.[14]

    Bulgaria

    War justifications

    Bulgaria was still resentful after its

    German and Austro-Hungarian forces. Bulgaria held claims on the region of Vardar Macedonia then held by Serbia following the Balkan Wars of 1912–1913 and the Treaty of Bucharest (1913).[15] As a condition of entering the war on the side of the Central Powers, Bulgaria was granted the right to reclaim that territory.[16][17]

    Zaian Confederation

    The Zaian Confederation began to fight against France in the Zaian War to prevent French expansion into Morocco. The fighting lasted from 1914 and continued after the First World War ended, to 1921. The Central Powers (mainly the Germans) began to attempt to incite unrest to hopefully divert French resources from Europe.

    Dervish State

    The

    French Empire between 1896 and 1925. During World War I, the Dervish State received many supplies from the German Empire and the Ottoman Empire
    to carry on fighting the Allies. However, looting from other Somali tribes in the Korahe raid eventually led to its collapse in 1925.

    Client states

    With the Bolshevik attack of late 1917, the General Secretariat of Ukraine sought military protection first from the Central Powers and later from the armed forces of the Entente.

    The Ottoman Empire also had its own allies in

    Army of Islam in the Battle of Baku
    .

    German client states

    Poland

    The Kingdom of Poland was a client state of Germany proclaimed in 1916 and established on 14 January 1917.[18] This government was recognized by the emperors of Germany and Austria-Hungary in November 1916, and it adopted a constitution in 1917.[19] The decision to create a Polish State was taken by Germany in order to attempt to legitimize its military occupation amongst the Polish inhabitants, following upon German propaganda sent to Polish inhabitants in 1915 that German soldiers were arriving as liberators to free Poland from subjugation by Russia.[20] The German government utilized the state alongside punitive threats to induce Polish landowners living in the German-occupied Baltic territories to move to the state and sell their Baltic property to Germans in exchange for moving to Poland. Efforts were made to induce similar emigration of Poles from Prussia to the state.[21]

    Ober Ost

    Ober Ost was a German client state created in October 1915. It was later turned into other client states in early 1918.

    Lithuania

    The Kingdom of Lithuania was a client state of Germany created on 16 February 1918.

    Belarus

    The Belarusian Democratic Republic was a client state of Germany created on 9 March 1918.

    Ukraine

    The

    Hetman Pavlo Skoropadskyi from 29 April 1918, after the government of the Ukrainian People's Republic was overthrown.[22]

    Crimea

    The Crimean Regional Government was a client state of Germany created on 25 June 1918. It was officially part of the Ukrainian State but acted separate from the central government. The Kuban People's Republic eventually voted to join the Ukrainian State.

    Courland and Semigallia

    The Duchy of Courland and Semigallia was a client state of Germany created on 8 March 1918.

    Baltic State

    The

    Estonian governorates and incorporate the recently established Courland and Semigallia into a unified state. An armed force in the form of the Baltische Landeswehr was created in November 1918, just before the surrender of Germany, which would participate in the Russian Civil War
    in the Baltics.

    Finland

    Finland had been an autonomous Grand Duchy within the Russian Empire since 1809, and the collapse of the Russian Empire in 1917 gave it its independence. Following the end of the Finnish Civil War, in which Germany supported the "Whites" against the Soviet-backed labour movement, in May 1918, there were moves to create a Kingdom of Finland. A German prince was elected. However, the Armistice intervened.

    Georgia

    The Democratic Republic of Georgia declared independence in 1918 which then led to border conflicts between the newly formed republic and the Ottoman Empire. Soon after, the Ottoman Empire invaded the republic and quickly reached Borjomi. This forced Georgia to ask for help from Germany, which they were granted. Germany forced the Ottomans to withdraw from Georgian territories and recognize Georgian sovereignty. Germany, Georgia and the Ottomans signed a peace treaty, the Treaty of Batum which ended the conflict with the last two. In return, Georgia became a German "ally". This time period of Georgian-German friendship was known as German Caucasus expedition.

    Don

    The Don Republic was founded on 18 May 1918. Their ataman Pyotr Krasnov portrayed himself as willing to serve as a pro-German warlord.

    Ottoman client states

    Jabal Shammar

    Arab state in the Middle East that was closely associated with the Ottoman Empire.[23]

    Azerbaijan

    In 1918, the

    Musavat Party, was then occupied by the Ottoman Empire, which expelled the Bolsheviks while supporting the Musavat Party.[24] The Ottoman Empire maintained a presence in Azerbaijan until the end of the war in November 1918.[24]

    Mountain Republic

    The Mountainous Republic of the Northern Caucasus was associated with the Central Powers.

    Qatar

    see also:Qatar in World War I [ru]
    Initially an Ottoman puppet, Qatar held an Ottoman garrison even following it's independence from the Ottomans in 1913. Following a treaty with Britain, it became a British puppet. It's Ottoman Garrison left prior to this on August 20th, 1915.[25]

    Yemen

    Yemen Vilayet or Yemen was an autonomous region of the Ottoman Empire that stayed allied with the Sultan and fought against the Allies during the South Arabian campaign.[26]

    Nations supported by the Central Powers

    States listed in this section were not officially members of the Central Powers. Still, during the war, they cooperated with one or more Central Powers members on a level that makes their neutrality disputable.

    Ethiopia

    Somaliland Campaign of 1915 to 1916, indirectly helping the Central Powers' cause.[27]

    Fearing the rising influence of Iyasu and the Ottoman Empire, the Christian nobles of Ethiopia conspired against Iyasu over 1915. Iyasu was first excommunicated by the

    Tafari Makonnen, was installed on the throne.[27]

    Liechtenstein

    from 1914 to 1918

    Liechtenstein was officially neutral throughout World War I, though the general population and government was supportive of the Central Powers, particularly Austria-Hungary, of which the two countries had been in a customs union since 1852. However, from September 1914 food deliveries from Austria-Hungary began to decrease, which quickly soured the initial war support.[28] By 1916 all food deliveries from Austria-Hungary had ceased, which forced Liechtenstein to seek closer ties with Switzerland in order to ensure food deliveries continued.[28][29] From 1916 Liechtenstein was embargoed by the Entente countries due to their connections to the Central Powers, which caused mass unemployment in the country.[30] The government remained sympathetic to the Central Powers until 7 November 1918, when the November 1918 Liechtenstein putsch took place and a new government took power.[31]

    Upper Asir

    Upper Asir revolted away from Asir in 1916 and fought against them. They were Ottoman-aligned but received support from Hejaz.[32]

    Kingdom of Greece

    The Kingdom of Greece was in a political dispute with Venizelists. The Central Powers supported the nation until King Constantine's abdication in 1917.[33]

    Romania

    Following their armistice with the Central Powers, Romania was involved in the Russian Civil War against both the Whites and the Reds. Romania fought alongside the Central Powers until the country rejoined the war against them on November 10th 1918.[34]

    Non-state combatants

    Other movements supported the efforts of the Central Powers for their own reasons, such as the radical Irish Nationalists who launched the Easter Rising in Dublin in April 1916; they referred to their "gallant allies in Europe". However, most Irish Nationalists supported the British and allied war effort up until 1916, when the Irish political landscape was changing. In 1914, Józef Piłsudski was permitted by Germany and Austria-Hungary to form independent Polish legions. Piłsudski wanted his legions to help the Central Powers defeat Russia and then side with France and the UK and win the war with them.

    Armistice and treaties

    Bulgaria signed an

    Hungary concluded ceasefires separately during the first week of November following the disintegration of the Habsburg Empire and the Italian offensive at Vittorio Veneto; Germany signed the armistice ending the war on the morning of 11 November 1918 after the Hundred Days Offensive, and a succession of advances by New Zealand, Australian, Canadian, Belgian, British, French and US forces in north-eastern France and Belgium. There was no unified treaty ending the war; the Central Powers were dealt with in separate treaties.[35]
