The Balkan Powder Keg Explodes: Austria-Hungary Vs Serbia

The conflict between Austria-Hungary and Serbia was a pivotal event in modern history, sparking a chain reaction that led to the First World War. The assassination of Archduke Franz Ferdinand by a Serbian nationalist in June 1914 was the catalyst for this escalation. Austria-Hungary, perceiving Serbia as a threat to its empire, responded by issuing an ultimatum to Serbia, demanding suppression of anti-Austrian sentiment and involvement in the investigation of the Archduke's assassination. Serbia's refusal to meet all demands led to Austria-Hungary declaring war on July 28, 1914, marking the beginning of a global conflict.

Austria-Hungary's annexation of Bosnia in 1908 angered Serbia

Austria-Hungary's annexation of Bosnia and Herzegovina in 1908 caused outrage in Serbia, damaging relations between the two countries. The annexation was the culmination of a series of events that began with the Congress of Berlin in 1878, which gave Austria-Hungary the right to occupy and administer Bosnia and Herzegovina, which were nominally still possessions of the Ottoman Empire. The provinces were coveted by many, including Austria and Hungary themselves, and the largely Slavic population had nationalist ambitions, which were supported by their fellow Slavs in nearby Serbia. This pan-Slavic nationalism was a significant factor in the anger felt in Serbia over the annexation.

In the lead-up to the annexation, there were diplomatic manoeuvres and agreements between Austria-Hungary, Russia, and the Ottoman Empire. In 1877, Russia agreed to Austria-Hungary's control over Bosnia and Herzegovina in exchange for Austria-Hungary's neutrality in the pending war with the Ottoman Empire. In 1908, the Austrian foreign minister, Count Lexa von Aehrenthal, met with the Russian foreign minister, Aleksandr Izvolsky, and gained Russia's agreement not to object to the annexation. In return, Austria-Hungary pledged not to object to Russia's interests in the Straits of Constantinople.

However, when the annexation was announced on October 6, 1908, it sparked outrage and protestations, not only from Serbia but also from other Great Powers and Austria-Hungary's Balkan neighbours. Serbia demanded that Austria cede a portion of Bosnia and Herzegovina to Serbia, and Russia, facing strong domestic opposition to the annexation, was forced to support these claims. The crisis permanently damaged relations between Austria-Hungary and its neighbours, especially Serbia, and contributed to the growing tensions in the volatile Balkans region.

The Bosnian Crisis, as it came to be known, was a significant factor in the complex web of alliances and rivalries that characterised pre-World War I Europe. It fuelled Serbian ambitions to unify southeast Europe's Slavic people and further strained relations with Austria-Hungary, which saw Serbia as a threat to its multi-ethnic empire. The crisis ultimately contributed to the outbreak of World War I in 1914, when Austria-Hungary declared war on Serbia following the assassination of Archduke Franz Ferdinand by a Serbian-backed terrorist.

The Bosnian Crisis of 1908-1909

The roots of this crisis can be traced back to the Congress of Berlin in 1878, where the Habsburg Empire gained the right to occupy and administer Bosnia and Herzegovina temporarily. However, these provinces remained official possessions of the Ottoman Empire. Over the years, Austria-Hungary invested significant efforts and resources to improve the region economically and strengthen its ties with these provinces. In 1908, when the Young Turks revolutionised Constantinople (now Istanbul), establishing a constitutional government, the Austrian foreign minister, Count Lexa von Aehrenthal, became determined to annex Bosnia and Herzegovina before the new Turkish regime could reclaim control.

On October 5, 1908, Austria-Hungary announced its decision to formally incorporate Bosnia and Herzegovina into its territory, causing an uproar among the Great Powers and its Balkan neighbours, particularly Serbia and Montenegro. Serbia, with its close geographical and ethnic ties to Bosnia and Herzegovina, vehemently opposed this annexation and demanded that Austria cede a portion of the annexed territory to Serbia. Russia, facing strong anti-Austrian sentiment at home, was compelled to support Serbia's claims.

Austria-Hungary, confident in the support of its ally Germany, threatened to invade Serbia if it persisted with its demands. Russia, unable to secure strong support from its ally France, ultimately conceded to Austria's annexation in March 1909 to avoid war. While the immediate crisis was averted, it left a lasting impact on international relations, souring relations between Austria-Hungary and its neighbours, especially Serbia, Italy, and Russia. The Bosnian Crisis thus played a role in shaping the alliances and enmities that would characterise World War I.

In April 1909, the Treaty of Berlin was amended to reflect the annexation, bringing a formal end to the crisis. However, the damage to diplomatic relations had already been done, and the crisis contributed to the volatile environment that would eventually erupt into World War I.

Austria-Hungary's ultimatum to Serbia in 1914

Relations between Austria-Hungary and Serbia had been tense in the years leading up to 1914, with Austria viewing Serbia as a threat to the stability of its multi-ethnic empire. Austria's annexation of Bosnia in 1908 and Serbian ambitions to unify southeast Europe's Slavic people further strained relations. Following the Balkan Wars of 1912-1913, Serbia emerged as a larger and more assertive presence in the region.

On June 28, 1914, Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne, and his wife were assassinated by a Serbian-backed Bosnian-Serb terrorist. Austria-Hungary suspected Serbian backing for the assassination and was determined to use the royal murder to crush the Serbian threat. On July 23, 1914, Austria-Hungary, with the support of its ally Germany, delivered an ultimatum to Serbia, demanding an inquiry into the assassination, among other things. The ultimatum was designed to be unacceptable to Serbia, and Austria-Hungary was prepared to go to war regardless of Serbia's response.

The ultimatum included a series of harsh demands, such as the suppression of anti-Austrian propaganda in Serbia and the participation of Austro-Hungarian officials in the inquiry and in the suppression of organizations hostile to Austria-Hungary. Serbia's response, delivered on July 25, accepted all demands except for the participation of Austro-Hungarian officials in the inquiry, citing it as a violation of its constitution and criminal procedure.

On July 28, 1914, one month after the assassination of the Archduke, Austria-Hungary, declaring Serbia's response insufficient, broke diplomatic relations and declared war on Serbia. This act of war stirred up old tensions and anxieties across Europe, drawing in the major powers, including Russia, France, and Britain, and ultimately leading to the First World War.

Serbia's partial acceptance of the ultimatum

On July 23, 1914, Austria-Hungary presented Serbia with an ultimatum, demanding, among other things:

• The suppression of all anti-Austrian propaganda within Serbia.
• The purging of the Serbian army and civil service of anti-Austrian agitators.
• The participation of Austrian officials in the investigation of the assassination of Archduke Franz Ferdinand and in the hunting down and prosecution of the ringleaders on Serbian territory.

Serbia's response to the ultimatum was delivered within the 48-hour deadline on July 25. Serbia agreed to accept the majority of the demands but rejected the final point concerning the participation of Austrian officials in investigations on Serbian soil, as this would infringe upon its state sovereignty. This demand was also unprecedented in relations between sovereign states.

Despite Serbia's partial acceptance of the ultimatum, the Austrian foreign minister refused to consider further negotiations, indicating that Vienna was not interested in a diplomatic solution. Instead, the Austro-Hungarian ambassador left Belgrade, severing diplomatic relations between the two countries.

The partial acceptance of the ultimatum by Serbia did not prevent the escalation of tensions and the eventual declaration of war by Austria-Hungary on July 28, 1914, marking the beginning of World War I.

Austria-Hungary's declaration of war on Serbia

Relations between Austria-Hungary and Serbia had been strained for years before the assassination of Archduke Franz Ferdinand. Austria had long viewed Serbia as a threat to the stability of its multi-ethnic empire. The annexation of Bosnia and Herzegovina by Austria-Hungary in 1908, formerly Ottoman territories, and Serbian ambitions to unite the Slavic people of Southeast Europe further exacerbated tensions. Following the Balkan Wars of 1912-1913, Serbia emerged as a more prominent and assertive power in the region.

On June 28, 1914, Archduke Franz Ferdinand, heir to the Austro-Hungarian throne, and his wife were assassinated by Gavrilo Princip, a Bosnian Serb student and member of a revolutionary organisation called Young Bosnia. This assassination triggered a chain of events that drew in Russia and the major European powers, marking the beginning of World War I. Suspecting Serbian backing for the assassination, Austria-Hungary aimed to utilise the royal murder to crush the Serbian threat once and for all.

On July 23, 1914, Austria-Hungary presented Serbia with an ultimatum, a series of ten demands designed to be unacceptable to provoke a war. These demands included the suppression of anti-Austrian propaganda in Serbia, the participation of Austro-Hungarian officials in suppressing organisations hostile to Austria-Hungary in Serbia, and the investigation of the archduke's assassination with Austro-Hungarian involvement. Serbia agreed to eight of the ten demands, but Austria-Hungary was unsatisfied and broke diplomatic relations on July 25.

On July 28, 1914, one month after the assassination of the Archduke, Austria-Hungary declared war on Serbia, marking the start of World War I. The declaration of war was influenced by the encouragement and support of its powerful ally, Germany, which sought a swift and decisive conflict. The dispute between Austria-Hungary and Serbia escalated and drew in other powers, including Russia, France, and Britain, transforming a localised conflict into a global war.
