Austria's Declaration Of War: Serbia's Impact

On July 28, 1914, Austria-Hungary declared war on Serbia, an event that effectively began the First World War. This declaration came a month after Archduke Franz Ferdinand of Austria and his wife were assassinated by a Serbian nationalist in Sarajevo. Threatened by Serbian ambition in the Balkans, Austria-Hungary, with the support of Germany, presented Serbia with an ultimatum on July 23, 1914. Although Serbia accepted most of the demands, Austria-Hungary broke diplomatic relations and went ahead with military preparedness measures. Russia, Serbia's ally, began its initial steps towards military mobilisation against Austria-Hungary, leading to a chain reaction of events that escalated the conflict.

The assassination of Archduke Franz Ferdinand

On June 28, 1914, Archduke Franz Ferdinand of Austria, heir presumptive to the Austro-Hungarian throne, and his wife, Sophie, Duchess of Hohenberg, were assassinated in Sarajevo, the provincial capital of Bosnia and Herzegovina. The assassination was carried out by a group of six Bosnian assassins, including Gavrilo Princip, a 19-year-old Bosnian Serb student. The political objective of the assassination was to free Bosnia and Herzegovina from Austrian-Hungarian rule and establish a common South Slav ("Yugoslav") state.

The day of the assassination was the feast of St. Vitus in Serbia, known as Vidovdan, which commemorates the 1389 Battle of Kosovo against the Ottomans. Princip and his accomplices were inspired by the heroism of Miloš Obilić, reenacting the Kosovo Myth. They received support from the Black Hand, a Serbian secret nationalist group, as well as from members of the Serbian military intelligence section. The assassins were provided with bombs, pistols, suicide pills, training, and a clandestine network of safe houses and agents to infiltrate weapons and operatives into Austria-Hungary.

On the day of the assassination, Franz Ferdinand and his wife were travelling in an open-topped car as part of a motorcade through Sarajevo. The motorcade's route had been published in advance, making them vulnerable to attack. When the motorcade passed by, Nedeljko Čabrinović threw a bomb at the car, but it bounced off and exploded under the wrong vehicle, wounding several people but leaving the Archduke and his wife unharmed. Čabrinović attempted to flee but was quickly apprehended.

The motorcade continued on to the town hall, where Franz Ferdinand and his wife attended a reception. Despite the failed assassination attempt, security arrangements were not heightened, and the couple insisted on continuing with their planned activities, including a visit to the wounded officers in the hospital. As their car attempted to reverse back onto the Appel Quay, Princip stepped up to the vehicle and fired two shots at close range, fatally wounding both Franz Ferdinand and his wife. Within minutes, they were both dead.

Austria-Hungary's ultimatum to Serbia

On July 23, 1914, Austria-Hungary issued an ultimatum to Serbia, demanding that the Serbian government condemn propaganda against Austria-Hungary and take steps to suppress it. The ultimatum also called for the dissolution of Serbian nationalist organisations, the removal of anti-Austrian individuals from positions of power, and the participation of Austrian officials in the investigation of the assassination of Archduke Franz Ferdinand.

The specific demands of the ultimatum included:

• A public condemnation of propaganda against Austria-Hungary and a pledge to suppress it
• The dissolution of the 'Narodna Odbrana' and other nationalist organisations
• The suppression of publications inciting hatred or contempt for Austria-Hungary
• The removal of anti-Austrian individuals from the Serbian army and civil service
• Cooperation with Austrian officials in suppressing subversive activities
• The prosecution of participants in the conspiracy to assassinate Archduke Franz Ferdinand
• Measures to prevent the smuggling of weapons and explosives across the Serbian border
• Disciplinary action against members of the Serbian Frontier Service who assisted the assassins
• An explanation for the hostile statements made by Serbian officials towards Austria-Hungary
• Prompt notification to the Austro-Hungarian government of the execution of these measures

Austria-Hungary gave Serbia 48 hours to respond to the ultimatum, and while Serbia accepted most of the demands, it rejected the participation of Austrian officials in investigations on Serbian territory as an infringement of its sovereignty. This rejection, along with encouragement from its ally Germany, led Austria-Hungary to declare war on Serbia on July 28, 1914, marking the beginning of World War I.

The role of Germany in the conflict

Germany played a pivotal role in the conflict between Austria-Hungary and Serbia, which ultimately escalated into World War I. Here is an overview of Germany's involvement:

German Support for Austria-Hungary

Germany was a key ally of Austria-Hungary and provided unconditional support for its military actions against Serbia. This backing was often referred to as a "blank cheque," encouraging Austria-Hungary to take aggressive steps against Serbia. Germany shared Austria-Hungary's concerns about Serbian ambition in the Balkans and wanted to curb Serbian influence in the region.

Encouraging War

German leaders encouraged Austria-Hungary to declare war on Serbia after the assassination of Archduke Franz Ferdinand by a Serbian nationalist. They urged swift action and even drafted the ultimatum presented to Serbia on July 23, 1914. This ultimatum was designed to be rigid and difficult for Serbia to accept, increasing the likelihood of conflict.

German-Austrian Alliance

The alliance between Germany and Austria-Hungary was a significant factor in the conflict. This alliance dated back to 1879 and was strengthened over time. Germany saw the preservation of Austria-Hungary as crucial to its foreign policy and was determined to support its ally militarily and diplomatically.

German Ambitions and Foreign Policy

Germany's foreign policy was driven by its ambitions, a perception of isolation, and a growing fear of being encircled by rival powers. Germany's desire to build a battle fleet, for example, initiated a naval arms race with Britain. Germany also wanted to counter French influence in Morocco, which further strained relations.

German Ultimatums and Declarations of War

As the crisis escalated, Germany issued ultimatums and declarations of war to other European powers. On August 1, Germany declared war on Russia, and on August 3, it declared war on France. These actions contributed to the widening conflict.

Invasion of Belgium

Germany's invasion of Belgium on August 4, 1914, was a significant development. This violation of Belgian neutrality prompted Britain to declare war on Germany, bringing another major power into the conflict.

German Strategy and War Plans

Germany's war strategy aimed to knock France out of the war before turning its full attention to Russia. They saw the Balkan crisis as an opportunity to inflict diplomatic setbacks on Russia and France. German generals feared Russia's growing military power and were eager to strike before it was too late.

In summary, Germany's role in the conflict between Austria-Hungary and Serbia was significant and multifaceted. Its support for Austria-Hungary, encouragement of military action, and own ambitions played a crucial part in escalating tensions and ultimately leading to World War I.

The mobilisation of troops

Austrian-Hungarian Mobilisation:

Austria-Hungary, encouraged by its ally Germany, was determined to punish Serbia for the assassination of Archduke Franz Ferdinand and crush any Serbian threat. On July 23, 1914, Austria-Hungary issued an ultimatum to Serbia, intending to provoke a war. Serbia's response, which conceded to all demands except one, was rejected by Austria-Hungary, and on July 28, it declared war on Serbia.

Austria-Hungary's mobilisation of troops began in earnest after declaring war. The Austro-Hungarian Army, known as the Imperial and Royal Army, consisted of three organisations: the Common Army, the Imperial-Royal Landwehr, and the Royal Hungarian Honvéd. The Common Army was the premier land force, tasked with securing the borders of the Monarchy. The Imperial-Royal Landwehr was the standing army of Austria, responsible for defending the country. The Royal Hungarian Honvéd, or Royal Hungarian Landwehr, served as the standing army of Hungary.

The Austro-Hungarian Army faced significant challenges due to its multi-ethnic composition. The empire included various ethnic groups such as Germans, Hungarians, Czechs, Poles, Ruthenians, Croats, and Romanians. This diversity created divisions within the ranks and made command and control difficult. Despite these challenges, Austria-Hungary mobilised approximately 3 million soldiers at the outbreak of World War I.

Impact on Other Countries:

The mobilisation of Austrian-Hungarian troops had a significant impact on other countries, particularly Serbia, Russia, and Germany:

• Serbia: Serbia, facing the declaration of war, immediately sought assistance from Russia and its leader, Tsar Nicholas II. Serbia began preparing for war, knowing that a conflict with Austria-Hungary was imminent.
• Russia: Russia, a supporter of Serbia, responded to the escalating crisis by ordering its forces to prepare for war on July 30, 1914. This mobilisation was seen as an aggressive act of war by Germany and Austria-Hungary. Russia's mobilisation against Austria-Hungary triggered a chain reaction, increasing tensions and bringing Europe closer to the brink of war.
• Germany: Fearing the advantage Russia would gain if it fully mobilised its massive army, Germany issued an ultimatum to Russia on July 31, demanding it demobilise. When Russia failed to reply, Germany declared war on Russia on August 1 and ordered its own general mobilisation. Germany's mobilisation was directed at invading France through Belgium, further escalating the conflict.

In conclusion, the mobilisation of troops by Austria-Hungary was a critical step towards World War I. It triggered a series of responses from other countries, particularly Serbia, Russia, and Germany, heightening tensions and ultimately contributing to the outbreak of the war. The multi-ethnic nature of the Austro-Hungarian Army presented challenges but did not deter their mobilisation efforts.

The declaration of war

On July 28, 1914, Austria-Hungary declared war on Serbia, marking the beginning of World War I. This declaration came one month after the assassination of Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne, and his wife, Sophie, Duchess of Hohenberg, by a Serbian-backed Bosnian Serb nationalist named Gavrilo Princip. This assassination heightened existing tensions between Austria-Hungary and Serbia, which had been strained due to Austria's annexation of Bosnia in 1908 and Serbian ambitions to unify Southeast Europe's Slavic people.

In the aftermath of the assassination, Austria-Hungary, with the encouragement and support of its ally Germany, decided to use the incident as a pretext to crush the Serbian threat once and for all. On July 23, 1914, Austria-Hungary presented Serbia with an ultimatum, demanding, among other things, the suppression of all anti-Austrian propaganda within Serbia and the allowance for Austria-Hungary to conduct its own investigation into the archduke's killing. Serbia accepted all demands except one, which would have infringed on its sovereignty.

On July 25, Austria-Hungary broke off diplomatic relations with Serbia and continued with military preparedness measures. Russia, Serbia's ally, began its initial steps towards military mobilisation against Austria-Hungary. The rest of Europe, including Britain, France, and Germany, watched with trepidation, fearing the outbreak of a wider conflict. Despite lobbying from the British Foreign Office for an international convention to moderate the conflict, Germany advised Austria-Hungary to proceed with its plans.

On July 28, after securing the unconditional support of Germany and in response to pressure from Germany for quick action, Austria-Hungary officially declared war on Serbia. This declaration of war set off a chain reaction, with Russia ordering mobilisation, Germany declaring war on Russia and France, and Britain eventually joining the conflict in response to Germany's invasion of Belgium. Thus, within a matter of weeks, the major powers of Europe were drawn into World War I.
