Austria-Hungary's Imperial Ambitions: The Serbian Question

The Austro-Hungarian invasion of Serbia in 1914 was the spark that ignited World War I. However, the relationship between the two nations was fraught long before this. Serbia, sandwiched between Austria-Hungary and the Ottoman Empire, was economically dependent on Austria, with Austrian-owned railways crisscrossing Serbian territory and Austrian banks lending heavily to Serbian businesses. This dynamic shifted in the early 1900s when King Peter I of Serbia rose to power and began to modernise and liberalise the nation, realigning its foreign policy away from Austrian influence. This angered Austrian ministers, who initiated trade sanctions, including banning future purchases of Serbian pork, one of its main exports. Despite this, Serbia's economy diversified and grew, and calls for greater political independence intensified. Serbian nationalism and pan-Slavism antagonised Austro-Hungarian leaders, who saw Serbia as a threat to the stability of their empire. The assassination of Archduke Franz Ferdinand by a Serbian nationalist in 1914 provided the pretext for Austria-Hungary to invade Serbia, with the goal of quashing its independence and denationalising its population.

The Austro-Hungarian invasion of Serbia

On July 23, 1914, Austria-Hungary presented Serbia with an ultimatum, demanding that all anti-Austrian propaganda within Serbia be suppressed and that they be allowed to investigate the archduke's killing. Serbia accepted all but one of the demands, but Austria-Hungary broke off diplomatic relations and proceeded with military preparedness measures. On July 28, 1914, exactly one month after the assassination, Austria-Hungary declared war on Serbia, marking the beginning of World War I.

The first invasion of Serbia, dubbed a "punitive expedition" by the Austro-Hungarian leadership, began on August 12, 1914, when the Austro-Hungarian Fifth Army crossed the Drina River. This invasion was short-lived, as the Royal Serbian Army successfully repelled three Austro-Hungarian attempts to invade, securing the first Allied victory of World War I at the Battle of Cer. The Austro-Hungarians launched a second invasion in September and a third in November but were unable to defeat the Serbs. By December 1914, the Royal Serbian Army had retaken Belgrade and forced the Austro-Hungarians to retreat.

Despite these setbacks, the Austro-Hungarian leadership, encouraged by their German allies, planned another invasion for the following year. In September 1915, Germany and Bulgaria entered into a secret military alliance, with Bulgaria agreeing to invade Serbia from the east. On October 5, 1915, Austria-Hungary and Germany launched a joint invasion, marking the fourth attempt to conquer Serbia. This time, they succeeded in breaching the Serbian front from the north and west, while Bulgaria attacked from the east. By January 1916, all of Serbia had been occupied, and the country was divided into occupation zones.

Serbia endured harsh treatment under occupation, with the occupiers aiming to denationalise and exploit the country. The occupation was marked by mass killings, deportations, forced labour, and economic exploitation. Hundreds of thousands of Serbian civilians were deported to internment and concentration camps, where many perished. Guerrilla groups, known as Chetniks, waged a resistance campaign against the occupiers, but they were unable to prevent the fall of Serbia.

It was not until September 1918 that Allied forces, including the Serbian Second Army, broke through the Salonica front, leading to the liberation of Serbia by November 1, 1918, bringing an end to the three-year Central Powers occupation.

The occupation of Serbia

The First Invasion of Serbia

The first invasion of Serbia, which the Austro-Hungarian leadership called a "punitive expedition", saw Austro-Hungarian forces occupy parts of Serbia for thirteen days. The invasion was aimed at eliminating Serbia as a threat and punishing it for fuelling South Slav irredentism in the Monarchy. The occupation was marked by massacres of civilians and the taking of hostages, with Austro-Hungarian troops committing numerous war crimes against the Serbian population. Between 3,500 and 4,000 Serb civilians were killed during the short occupation.

The Second and Third Invasions of Serbia

On September 8, 1914, the Austro-Hungarians launched a second invasion, this time engaging all their forces. However, they were pushed back by the Serbian forces. On November 5, 1914, the Austro-Hungarians launched a third offensive and managed to capture Belgrade, forcing the Royal Serbian Army to retreat.

The Fourth Invasion of Serbia and Occupation

On October 5, 1915, Austria-Hungary and Germany launched a joint invasion of Serbia, marking the fourth attempt to conquer the country. This offensive was led by German General August von Mackensen. Belgrade, the Serbian capital, was evacuated on October 9, and by January 1916, all of Serbia had been occupied by the Central Powers. Serbia was divided into two separate occupation zones: an Austro-Hungarian zone and a Bulgarian zone, both governed under a military administration. The goal of the Austro-Hungarian administration was to denationalise the Serb population and exploit the country's economic resources.

Life Under the Occupation

The Austro-Hungarian occupational authorities implemented a series of measures aimed at depoliticising and denationalising the Serbian population. Public gatherings and political organisations were banned, and the Cyrillic script was prohibited in schools and public spaces. Serbian cultural institutions, such as the Royal Serbian Academy, the National Museum, and the National Library, were closed down and looted. The occupational authorities also carried out summary executions, took hostages, and burned villages in punitive raids. During the occupation, between 150,000 and 200,000 Serb civilians were deported to internment and concentration camps in Austria-Hungary.

Liberation of Serbia

In September 1918, Allied forces, led by the Serbian Second Army and the Yugoslav Volunteer Division, broke through the Salonica front, leading to the surrender of Bulgaria and the liberation of Serbia. By November 1, 1918, all of pre-war Serbia had been liberated, bringing an end to the three-year occupation.

The Serbian response to occupation

• Guerrilla Warfare: Immediately after the withdrawal of the Royal Serbian Army, armed individuals and small groups of insurgents called "Chetniks" waged a guerrilla campaign against the Austro-Hungarian occupiers. These Chetniks, often considered heroes by the local population, had a long tradition of guerrilla warfare during the Ottoman rule. They enjoyed strong local support, with their actions depicted in epic folk poetry. The first organised guerrilla group was formed in early 1916 in the Novi Pazar and Kosovska Mitrovica districts, led by former army captain Kosta Vojinović.
• Resistance and Uprisings: Serbia witnessed multiple resistance movements and uprisings during the occupation. In February 1917, a rebellion led by Vojinović broke out near Kuršumlija and Prokuplje, liberating several towns. A larger-scale uprising occurred in the Toplica District in Bulgarian-occupied Serbia, where 4,000 armed men and women managed to liberate a significant area before being suppressed. Despite harsh repression, guerrilla groups survived and supported Allied offensive operations in the summer of 1918.
• Allied with Allies: Serbian resistance fighters coordinated their efforts with the Allies. In September 1918, the Allied forces, spearheaded by the Serbian Second Army and the Yugoslav Volunteer Division, broke through the Salonica front, leading to the liberation of Serbia from Austro-Hungarian occupation.
• International Support: Serbia's resistance efforts gained international attention and support. American, Swiss, and Swedish humanitarian organisations offered assistance, and campaigns were organised asking for "Relief for Agonized Serbia."
• Intelligence and Espionage: Serbian resistance groups likely engaged in intelligence-gathering and espionage activities to support their operations and disrupt the occupiers' plans.
• Propaganda and Counter-Propaganda: The occupiers attempted to use propaganda, such as the "Belgrader Nachrichten," to convince Serbian soldiers to desert. However, Serbian resistance groups may have also utilised counter-propaganda to expose the atrocities committed by the occupiers and maintain morale among the Serbian population.
• Partisan Activities: Besides armed resistance, Serbs engaged in partisan activities, including sabotage and disruption of railways, supply lines, and communication networks. This forced the occupiers to allocate significant resources to counter these activities.
• Diplomatic Efforts: While not directly responding to the occupation, Serbian diplomatic efforts before the war played a role in shaping the international response to the crisis. Serbia's treaty of mutual assistance with Russia likely contributed to Russia's mobilisation against Austria-Hungary, which had broader implications for the conflict.

Overall, the Serbian response to occupation was characterised by resilience, adaptability, and a combination of military, political, and diplomatic strategies. The resistance efforts played a crucial role in ultimately liberating Serbia from Austro-Hungarian rule.

The role of nationalism

Nationalism played a significant role in the complex dynamics between Austria-Hungary and Serbia leading up to World War I. Here is an examination of the role of nationalism in this context:

Serbian Nationalism:

Serbia, having gained independence from the Ottoman Empire in the 19th century, was a hotbed of nationalism, agitation, and polarisation. Serbian nationalism was fuelled by a desire to reclaim Serbian territories from the Austro-Hungarian Empire and a sense of protecting the rights of Slavic people in the region. This led to the formation of nationalist groups like the People's Defence (Narodna Odbrana), the Black Hand (Crna Ruka), and Young Bosna (Mlada Bosna). These groups used propaganda and agitation to promote their agenda and became increasingly radical and violent.

Serbian nationalism posed a direct threat to the Austro-Hungarian Empire, as it sought to unite South Slavs, including those living within the Empire's borders. This threat was exacerbated by Serbia's military victories in the Balkan Wars, which made it the most powerful nation in the Balkans. As a result, Serbian nationalism contributed to rising tensions and ultimately played a catalytic role in the assassination of Archduke Franz Ferdinand, which sparked World War I.

Austro-Hungarian Nationalism:

The Austro-Hungarian Empire, encompassing diverse ethnic groups, faced challenges due to the rise of nationalism within its borders. Nationalist sentiments among Poles, Ruthenians, Czechs, Slovaks, and South Slavs, including Serbs, Croats, and Slovenes, threatened the unity of the Empire. The Empire's leaders viewed Serbian nationalism as an existential threat, fearing that if South Slavs left, other groups might follow suit.

Chief of the Austrian General Staff, Conrad von Hötzendorf, had repeatedly called for war with Serbia before 1914 due to these concerns. The assassination of Archduke Franz Ferdinand provided the Empire with the perfect excuse to go to war with Serbia, as it sought to preserve its dominance and suppress the nationalist aspirations of its constituent ethnic groups.

The aftermath of the conflict

The Human Cost and Atrocities

The conflict between Austria-Hungary and Serbia resulted in immense human suffering. During the initial invasion of Serbia, Austro-Hungarian forces committed numerous atrocities against Serbian civilians, including massacres, hostage-taking, and the destruction of villages. These war crimes left thousands of civilians dead and caused widespread fear and trauma among the Serbian population. The occupying forces implemented a brutal regime, characterised by martial law, public executions, and the deportation of civilians to internment and concentration camps. It is estimated that between 150,000 and 200,000 Serbian men, women, and children were deported to camps, where many perished due to harsh conditions, disease, and starvation.

Occupation and Resistance

Following the successful invasion, Austria-Hungary, together with its ally Bulgaria, occupied Serbia. The country was divided into occupation zones, with the Austro-Hungarian zone covering the northern three-quarters of Serbia. The occupation authorities implemented a policy of denationalisation and depoliticisation, banning Serbian cultural institutions, political organisations, and even the Cyrillic script. The occupiers exploited Serbia's economic resources, confiscating materials and requisitioning food, leading to famine and further hardship for the Serbian people. In response, Serbian resistance groups, known as Chetniks, waged a guerrilla campaign against the occupiers. The Chetniks enjoyed strong local support and posed a constant threat to the occupying forces.

International Reactions and Escalation

The conflict between Austria-Hungary and Serbia quickly escalated into a wider European war, as other powers became involved. Russia, Serbia's ally, began mobilising its military in response to Austria-Hungary's aggression. This prompted Germany, Austria-Hungary's powerful ally, to declare war on Russia and expand the conflict. The entry of these major powers led to a chain reaction, with France, Britain, and other nations joining the war on opposing sides. The assassination of Archduke Franz Ferdinand, which sparked the initial conflict, thus became a catalyst for World War I, engulfing the continent and resulting in unprecedented loss of life.

Liberation and Aftermath

The occupation of Serbia lasted until the final stages of World War I. In September 1918, Allied forces, including the Serbian Second Army, broke through the enemy lines, leading to the liberation of Serbia by November 1, 1918. The occupation ended with the retreat of Austro-Hungarian and German troops from Serbian territory. The liberation brought an end to the brutal occupation regime and allowed Serbia to regain its independence. However, the impact of the conflict extended beyond the war's conclusion, shaping the political and social landscape of the region for decades to come.

The conflict between Austria-Hungary and Serbia had far-reaching consequences, not only for the people of Serbia but also for the course of European history. The aftermath of the conflict was characterised by occupation, resistance, and the escalation of tensions that led to World War I. The human cost was devastating, with countless lives lost and communities shattered. The liberation of Serbia marked a turning point, allowing the country to emerge from the shadow of occupation and chart its path towards recovery and self-determination.
