Austria's Fight Against Serbia: The 1914 Conflict Explored

On July 28, 1914, Austria-Hungary declared war on Serbia, marking the beginning of World War I. This declaration came exactly a month after the assassination of Archduke Franz Ferdinand of Austria and his wife in Sarajevo by a Serbian nationalist. Austria-Hungary, with the encouragement of its powerful ally Germany, presented Serbia with an ultimatum on July 23, 1914, demanding the suppression of anti-Austrian propaganda and the right to conduct an investigation into the archduke's killing. Despite Serbia accepting all but one of the demands, Austria-Hungary broke diplomatic relations and proceeded with military preparations, ultimately declaring war.

Archduke Franz Ferdinand's assassination

On 28 June 1914, Archduke Franz Ferdinand of Austria, heir to the Austro-Hungarian throne, and his wife, Sophie, Duchess of Hohenberg, were assassinated in Sarajevo, Bosnia. The assassination was carried out by a group of Bosnian assassins, including Gavrilo Princip, a Bosnian Serb student and member of a revolutionary group called Young Bosnia. The group's political objective was to free Bosnia and Herzegovina from Austrian-Hungarian rule and establish a common South Slav state.

The assassination of Archduke Franz Ferdinand was a key event that led to World War I. On 28 July 1914, exactly one month after the assassination, Austria-Hungary declared war on Serbia, marking the beginning of the First World War.

The day of the assassination, 28 June, holds significance as the feast of St. Vitus in Serbia, known as Vidovdan. It commemorates the 1389 Battle of Kosovo against the Ottomans, during which Sultan Murad I was assassinated in his tent by a Serb. Princip and his accomplices were inspired by this act of heroism and sought to emulate it.

In the lead-up to the assassination, Princip and his fellow conspirators received weapons, training, and support from the Black Hand, a Serbian secret nationalist group with ties to the Serbian military. Major Vojislav Tankosić, a member of the Black Hand, provided the assassins with bombs, pistols, and suicide pills, and trained them in their use. The assassins also had access to a clandestine network of safe houses and agents that facilitated the infiltration of weapons and operatives into Austria-Hungary.

On the day of the assassination, Franz Ferdinand and his wife were travelling in an open-top car as part of a motorcade through Sarajevo. The security measures for the motorcade were limited, with only about 60 police officers on duty, despite the procession route being four miles long. Gavrilo Princip, positioned along the motorcade route, shot the Archduke and his wife at point-blank range. Franz Ferdinand was hit in the jugular vein, while Sophie was struck in the abdomen. The couple succumbed to their injuries and died by 11:30 am on the same day.

The assassination sparked a diplomatic crisis between Austria-Hungary and Serbia, known as the July Crisis. Austria-Hungary presented Serbia with an ultimatum, demanding, among other things, the suppression of anti-Austrian propaganda and the allowance for Austria-Hungary to conduct its investigation into the assassination. Serbia accepted most of the demands but rejected the ultimatum, leading Austria-Hungary to declare war. The conflict quickly escalated, drawing in other European powers and resulting in the First World War.

Austria-Hungary declares war

On July 28, 1914, Austria-Hungary declared war on Serbia, igniting the flames of World War I. The declaration came exactly one month after Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne, and his wife were assassinated by a Serbian nationalist in Sarajevo. This assassination, occurring on June 28, 1914, set off a chain of events that led to the first global conflict.

Austria-Hungary, encouraged and supported by its powerful ally Germany, determined that a military invasion of Serbia was necessary. They viewed Serbian ambition in the Balkans as a threat and decided to crush it. On July 23, 1914, Austria-Hungary presented Serbia with an ultimatum, a series of ten demands designed to provoke a war. Serbia accepted all demands except one, which concerned the involvement of Austro-Hungarian officials in the investigation of the Archduke's assassination.

On July 25, Austria-Hungary broke off diplomatic relations with Serbia and began military preparations. Russia, Serbia's ally, started its initial steps towards military mobilisation against Austria-Hungary. The rest of Europe watched with trepidation, fearing that the conflict would escalate into a broader European war. Despite lobbying for an international convention to moderate the conflict, the British efforts were rejected by Germany, which advised Austria-Hungary to proceed with its plans.

On July 28, Austria-Hungary officially declared war on Serbia. Russia responded by ordering mobilisation in the districts facing Galicia, the common front with the Austro-Hungarian Empire. That night, Austrian artillery divisions bombarded Belgrade across the Danube River, although the attack was brief and ineffectual. The stage was now set for a wider conflict, as the major powers of Europe began to mobilise and declare war on each other, drawing the continent into the First World War.

The Serbian campaign, led by Austrian General Oskar Potiorek, consisted of three unsuccessful invasion attempts that were repelled by the Serbian and Montenegrin armies. The Serbian victory at the Battle of Cer is considered the first Allied victory of World War I, and the defeat of the Austro-Hungarian Army was one of the great upsets of modern military history. The conflict in the Balkans escalated, drawing in other powers and expanding the war beyond the continent.

Serbian Campaign

The Serbian Campaign of 1914 was a significant military operation during World War I, marking the first major confrontation between the Central Powers (led by Austria-Hungary) and the Allied Powers (led by the Kingdom of Serbia). The campaign started on July 28, 1914, when Austria-Hungary declared war on Serbia and bombarded Belgrade. This came after the assassination of Archduke Franz Ferdinand of Austria by a Serbian nationalist in Sarajevo on June 28, 1914.

The first invasion of Serbia was led by General Oskar Potiorek and began on August 12, 1914. The Austro-Hungarian forces, known as Balkanstreitkräfte, consisted of the 5th and 6th Armies, attacking Serbia from the west and north. The Serbian Army, commanded by General Radomir Putnik, utilised their knowledge of the rugged terrain and the strategic advantage of the rivers. They defeated the 5th Army at the Battle of Cer, forcing the Austro-Hungarian forces to retreat.

After the initial failure, Austria-Hungary regrouped and launched a second invasion in September 1914. The Serbs pushed the 5th Army back into Bosnia and forced the remains of the Balkanstreitkräfte to retreat to avoid encirclement. On October 24, Potiorek launched a third invasion, capturing Belgrade, the Serbian capital, on December 2, 1914. However, a successful Serbian counter-offensive at the Battle of Kolubara expelled the Central Powers' forces from Serbian territory before the end of December, ending the first phase of the campaign.

Potiorek was relieved of his command after the three invasions failed to achieve their objectives. The campaign resulted in heavy losses for both sides. The Habsburg forces suffered 28,000 dead and 122,000 wounded, while Serbian losses included 22,000 dead, 91,000 wounded, and 19,000 captured or missing.

In October 1915, the Central Powers returned with a massive offensive during the second Serbian Campaign, successfully invading Serbia from three sides with Bulgarian, Austro-Hungarian, and German forces. This resulted in the Great Retreat and the occupation of Serbia, which was divided between the Austro-Hungarian Empire and Bulgaria. However, the Allies launched the Vardar Offensive in September 1918, liberating Serbia, Albania, and Montenegro. Serbian forces entered Belgrade on November 1, 1918.

Balkan crisis

The Balkan Wars, a series of two conflicts that took place in the Balkan states in 1912 and 1913, were a prelude to World War I. The First Balkan War was fought between the members of the Balkan League—Serbia, Bulgaria, Greece, and Montenegro—and the Ottoman Empire. The Second Balkan War was fought between Bulgaria and the other four original combatants of the first war, plus Romania. The Balkan Wars were marked by ethnic cleansing, with all parties responsible for grave atrocities against civilians.

The First Balkan War began on October 8, 1912, when Montenegro declared war on Turkey, and the other members of the Balkan League followed suit ten days later. The Balkan allies were victorious, and the Ottoman Empire lost almost all of its remaining European territory, including Macedonia and Albania. The Second Balkan War began on June 1, 1913, when Serbia, Greece, and Romania quarrelled with Bulgaria over the division of their joint conquests in Macedonia. Bulgaria was defeated, and Greece and Serbia divided up most of Macedonia.

The political consequences of the Balkan Wars were significant. Apart from Turkey, the real loser was Austria-Hungary, which became relatively weaker as a much-enlarged Serbia pushed for the union of South Slavic peoples. The partitioning of the Sanjak of Novi Pazar between Serbia and Montenegro made it impossible for Austria-Hungary to intervene in the Balkans during the July Crisis of 1914. The Austro-Hungarian ultimatum to Serbia on July 23, 1914, was thus seen as naked aggression. The wars also altered the structure of alliances in the Balkans. Dissatisfied Bulgaria now looked to Austria-Hungary for support, while Romania moved out of the influence of the Triple Alliance and toward the Triple Entente.
