Ottoman-German Alliance\n\nThe Ottoman-German Alliance was a secret treaty of military alliance signed at Constantinople on 2 [August 1914](https://www.edgepedia.org/august-1914) between the Ottoman Empire and the [German Empire](https://www.edgepedia.org/german-empire), binding the Ottomans to enter the war on Germany's side if Russia intervened against

to the study *İttifaktan Savaşa*, the Ottoman leadership hoped an alliance would end its political isolation, secure German military and economic support, and recover territories lost in the [Tripolitania](https://www.edgepedia.org/tripolitania) and Balkan wars.[6](https://dergipark.org.tr/en/pub/ausbf/article/809254) Historian Mustafa Aksakal describes the leadership as seeking the German alliance as the only way out of a web of international threats and domestic insecurities.[7](https://www.cambridge.org/core/books/ottoman-road-to-war-in-1914/16E2237CC577FE6CC029623B974607EF)\n\nGermany's aims were complementary: it wanted to incite rebellion in Britain's Muslim colonies and to close the [Suez Canal](https://www.edgepedia.org/suez-canal), while the Ottomans sought to secure the straits and Eastern Anatolia, strengthen their position in the [Arabian Peninsula](https://www.edgepedia.org/arabian-peninsula) and over the Suez Canal, and maintain their leadership of the Islamic world.[2](https://ttk.gov.tr/osmanli-imparatorlugunun-i-dunya-harbine-girisi-ve-carpistigi-cepheler/) After declaring war on Russia on 1 August 1914, Germany needed a military power to engage Russian forces and saw the Ottoman alliance as a lifeline.[4](https://dergipark.org.tr/tr/download/article-file/1340439) Berlin had rejected earlier Ottoman attempts at an alliance, and, according to Mustafa Aksakal's *The Ottoman Road to War in 1914*, Chancellor Theobald von Bethmann Hollweg instructed Wangenheim on 31 July to sign only if Turkey could undertake action against Russia worthy of the name.[8](https://www.ethicsandinternationalaffairs.org/online-exclusives/the-ottoman-road-to-war-mustafa-aksakal-on-the-ottoman-empire-and-wwi) • [9](https://api.pageplace.de/preview/DT0400.9781400877591_A26060207/preview-9781400877591_A26060207.pdf) \n\n## Course of events\n\nTerms. Article 1 committed both parties to strict neutrality in the Austro-Hungarian-Serbian conflict; Article 2 provided that Russian active military measures would trigger the casus foederis for Turkey as for Germany; Article 3 placed the German military mission at Turkey's disposal with effective influence on the general conduct of the army; Article 4 obligated Germany to defend Ottoman territory, if necessary by force of arms.[1](https://web.archive.org/web/20110811023936/https:/avalon.law.yale.edu/20th_century/turkgerm.asp) The treaty was to remain secret.[1](https://web.archive.org/web/20110811023936/https:/avalon.law.yale.edu/20th_century/turkgerm.asp)\n\nFrom signature to war. Germany declared war on Russia at 17:00 on 1 August 1914, but this did not itself activate the treaty, whose casus foederis required Russian active military measures against Austria-Hungary; nevertheless, the Ottoman Empire had committed itself by signature to enter the war on Germany's side if that condition arose; the Ottoman government proclaimed mobilization and armed neutrality on 3 August 1914, while another account dates the neutrality declaration to 4 August, after strong reactions from cabinet members and the Entente powers.[2](https://ttk.gov.tr/osmanli-imparatorlugunun-i-dunya-harbine-girisi-ve-carpistigi-cepheler/) • [4](https://dergipark.org.tr/tr/download/article-file/1340439) The German warships Goeben and Breslau passed through the [Dardanelles](https://www.edgepedia.org/dardanelles) on 10 August 1914, were renamed Yavuz and Midilli, given [Ottoman flags](https://www.edgepedia.org/flags-of-the-ottoman-empire) and crews in Ottoman uniform, and their German commander Admiral Souchon was appointed first commander of the Ottoman navy.[2](https://ttk.gov.tr/osmanli-imparatorlugunun-i-dunya-harbine-girisi-ve-carpistigi-cepheler/) • [3](https://www.belleten.gov.tr/eng/full-text/279/tur)\n\nThe German battle cruiser Goeben bombarded the Russian port of [Sevastopol](https://www.edgepedia.org/sevastopol) on 29 October 1914, an act that led to the Ottoman entry into the war.[5](https://doi.org/10.37879/belleten.2004.687) • [2](https://ttk.gov.tr/osmanli-imparatorlugunun-i-dunya-harbine-girisi-ve-carpistigi-cepheler/)\n\n## Outcome and losses\n\nOne assessment of the decision holds that it produced a crushing Ottoman defeat within four years and the end of the centuries-long rule of the [House of Osman](https://www.edgepedia.org/house-of-osman) within nine.[10](https://commons.emich.edu/cgi/viewcontent.cgi?article=1836&context=theses)\n\n## Consequences and political influence\n\nThe treaty was signed secretly by a small group who concealed it even from cabinet members: it was negotiated by Minister of War Enver, Minister of the Interior Talat, and Minister of the Navy Cemal, all pashas, and signed for the Ottoman Empire by Premier and Foreign Minister Said Halim Pasha and for Germany by Baron von Wangenheim, while the rest of the cabinet and Parliament were kept in the dark.[5](https://doi.org/10.37879/belleten.2004.687) • [13](https://avalon.law.yale.edu/20th_century/turkgerm.asp) Three days after signature, Enver told the Russian military attache in Istanbul that if Russia quieted Turkish fears in the Caucasus, Istanbul would withdraw its forces from that front, an early sign that the government intended to delay active entry.[5](https://doi.org/10.37879/belleten.2004.687) After signing, Istanbul's real aim was to preserve the German alliance into the postwar period, draw on German resources and protection, and consolidate its domestic and military power.[8](https://www.ethicsandinternationalaffairs.org/online-exclusives/the-ottoman-road-to-war-mustafa-aksakal-on-the-ottoman-empire-and-wwi) Facing harsh criticism at home for siding with Germany, the government used Ottoman military publications to legitimize the alliance, presenting it as the least bad option and an inevitable outcome of British and Russian anti-Ottoman policies.[11](https://osmanlimirasi.net/index.php/omad/article/view/18)\n\n## Historians' assessment\n\nAksakal argues, on the basis of Ottoman and European sources, that responsibility for the Ottoman entry into the war went far beyond [Enver Pasha](https://www.edgepedia.org/enver-pasha), challenging the consensus that Enver alone, in thrall to the Germans, dictated the decision of late October 1914.[7](https://www.cambridge.org/core/books/ottoman-road-to-war-in-1914/16E2237CC577FE6CC029623B974607EF) He characterizes the alliance as a hastily made arrangement rather than the culmination of careful German plans, and as an arrangement between diplomatic equals despite the enormous disparity in military, economic, and financial power between the two countries.[9](https://api.pageplace.de/preview/DT0400.9781400877591_A26060207/preview-9781400877591_A26060207.pdf) A university thesis reaches a compatible conclusion: Ottoman interests were not subordinated to Germany and Ottoman independence was not seriously compromised, and by the treaty's terms Germany guaranteed Ottoman territory, promised not to make a separate peace until lost territory was recovered, and agreed to a large loan.[10](https://commons.emich.edu/cgi/viewcontent.cgi?article=1836&context=theses) After the defeat, the wartime closeness gave way to a rupture in memory: the [Gallipoli](https://www.edgepedia.org/gallipoli) victory, seen during the war as a shared success of the alliance, was claimed by Turks as a Turkish victory and by Germans as the work of German commanders and technical support.[3](https://www.belleten.gov.tr/eng/full-text/279/tur) Historians of the Turkish-German relationship assess the wartime alliance as a complementary relationship of interests and a strategic partnership aiming at joint victory.[12](https://doi.org/10.55842/talid.1577160)\n\n## References\n\n1.
