On August 1, 1914, Austria-Hungary's position was already one of war. Having declared war on Serbia on July 28, 1914, following the assassination of Archduke Franz Ferdinand, Austria-Hungary's invasion of Serbia had begun. This declaration of war, with the support of Germany, set off a chain reaction of counter-mobilizations, leading to World War I. By August 1, Germany had declared war on Russia, who had mobilized in support of Serbia. The Austro-Hungarian forces faced significant challenges, including conducting their invasion with fewer troops than planned and in difficult terrain. The army was divided, with a smaller part attacking Serbia and the larger part confronting the formidable Imperial Russian Army. The invasion of Serbia proved to be a costly disaster, with high casualties and no territorial gains by the end of the year. The early weeks of August 1914 saw the Austro-Hungarian forces in retreat on multiple fronts, and the empire would soon face a dire military situation.

Austria-Hungary's declaration of war on Serbia
On 28 July 1914, Austria-Hungary declared war on Serbia, marking the start of World War I. This declaration came exactly one month after the assassination of Archduke Franz Ferdinand, heir presumptive to the Austro-Hungarian throne, and his wife, Sophie, Duchess of Hohenberg, by Gavrilo Princip, a Bosnian Serb nationalist and member of a Serbian-backed paramilitary organisation.
The assassination of Franz Ferdinand and his wife in Sarajevo on 28 June 1914 set off a series of diplomatic and military escalations among the major powers of Europe, known as the July Crisis. This event led to a global war, with Austria-Hungary seeking to inflict a military blow on Serbia, demonstrating its strength and attempting to suppress Serbian support for Yugoslav nationalism, which it viewed as a threat. The Austro-Hungarians also wanted to confront Serbia militarily before it could incite a revolt, using the assassination as a pretext.
In the aftermath of the assassination, Austria-Hungary presented Serbia with an ultimatum, a list of ten demands known as the July Ultimatum, expecting that Serbia would not be able to accept all of them. Serbia agreed to comply wholly or in part with nine of the demands but rejected the final demand, which would have resulted in a significant infringement of its sovereignty. Serbia had obtained guarantees of support from the Russian government, which had an alliance with France, against Austria-Hungary.
With the encouragement and support of Germany, which sought a swift war to destroy Serbia, Austria-Hungary declared war. The German Emperor refused to assent to calling a European Conference to prevent war, and Germany's policy was to present the world with a fait accompli. The German military supported the idea of an Austro-Hungarian attack on Serbia as the best way to start a general war. The German Ambassador to Austria-Hungary, Heinrich von Tschirschky, conveyed to the Austro-Hungarian government that Germany would support them "through thick and thin" in their actions against Serbia.
The invasion of Serbia by Austria-Hungary in 1914 was a disaster, with the Austro-Hungarian Army suffering heavy losses and making little territorial gain. The invasion resulted in cruel havoc wreaked upon Serbian civilians, with Habsburg troops massacring thousands and burning villages. By the end of 1914, Austria-Hungary faced a dire military situation, with its forces in full retreat from Serbia.

The July Ultimatum
Austria-Hungary, with the full support of its allies in Berlin, pursued a hard-line policy towards Serbia, intending to force a military conflict that would end quickly and decisively before Serbia's powerful ally, Russia, had time to react. The ultimatum demanded that the Serbian government accept an Austro-Hungarian inquiry into the assassination, despite Serbia's claim that it was already conducting its own investigation.
The Council debated the harshness of the demands, with Tisza, the Hungarian Prime Minister, warning that an attack on Serbia would likely lead to Russian intervention and potentially a world war. However, the majority favoured war, and the ultimatum was designed to be so harsh that its rejection was almost certain.
Serbia's response, delivered just before the 6 p.m. deadline on July 25, accepted all but one of the demands. Serbia refused to accept Austria-Hungary's participation in any internal inquiry, stating that it would not allow foreign interference in its judicial process. This partial acceptance was not enough to satisfy Austria-Hungary, and they declared war.

The invasion of Serbia
On 28 July 1914, Austria-Hungary declared war on Serbia, marking the beginning of World War I. This declaration of war followed the assassination of Archduke Franz Ferdinand, heir to the Austro-Hungarian throne, by Gavrilo Princip, a Bosnian Serb nationalist, in Sarajevo on 28 June 1914. The Austro-Hungarian foreign office, with the support of Germany, seized the opportunity to address the "Serbian danger" and drafted an ultimatum holding the Serbian government responsible for the assassination.
The ultimatum, known as the July Ultimatum, consisted of ten demands, expecting that Serbia would not accept and provide a justification for the impending invasion. Serbia accepted nine demands and partially accepted the remaining one, which entailed constitutional changes in the Serbian government. Austria-Hungary, unsatisfied with Serbia's response, declared war.
The first invasion of Serbia had severe consequences for the Austro-Hungarian military. It forced the transfer of two divisions from the 2nd Army to Potiorek's force, impacting their ability to fight on other fronts. The Austro-Hungarian Army suffered heavy losses, with 227,000 casualties out of a force of 450,000 men. The invasion also resulted in significant civilian casualties, with Serbia losing more than 1,200,000 inhabitants during the war, including both military and civilian deaths.

Austria-Hungary's invasion of Albania
On 28 July 1914, Austria-Hungary declared war on Serbia, marking the start of World War I. Over the course of July and August 1914, a series of counter-mobilizations were set off as Russia mobilized in support of Serbia. On 6 August 1914, Emperor Franz Joseph I of Austria-Hungary signed the declaration of war on Russia.
The first wave of the invasion began in 1915, when combined German, Austro-Hungarian, and Bulgarian forces overran Serbia. The Serbian army was forced to retreat across the mountain passes of northern Albania towards the Adriatic coast. With the Serbian army in retreat, Austria-Hungary, along with Bulgaria, took the opportunity to occupy parts of Albania. The Kingdom of Bulgaria occupied the eastern part of Albania, while Austria-Hungary occupied the northern and western regions. Many ethnic Albanians joined Bulgaria in their fight against Serbia. However, the Bulgarian-Austrian alliance faced resistance from Albanian guerrillas, who joined forces with the invading armies of Italy and France.
The second wave of the invasion occurred in 1916, when Austria-Hungary and Bulgaria launched a double invasion of Albania. This forced Essad Pasha Toptani, who had previously aligned Albania with the Entente Powers, to leave his proclaimed Senate of Central Albania and once again declare war on Austria-Hungary. In March 1916, the Austrian army took control of Elbasan, previously held by the Bulgarians, and then moved towards Berat. The Bulgarian-Austrian alliance was active in supporting Muslim rebels in Albania, who were seeking to overthrow the pro-Entente administration of Toptani. The Central Powers provided military aid, with Ottoman officers commanding rebel forces and Austria-Hungary supplying weapons and ammunition.
The occupation of Albania by Austria-Hungary and its allies continued until the end of the war. In 1918, a multinational Allied force pushed out the occupying armies and brought the territory of Albania back under its control.

Austria-Hungary's alliance with Germany
On 28 June 1914, Archduke Franz Ferdinand of Austria, heir presumptive to the Austro-Hungarian throne, and his wife, Sophie, Duchess of Hohenberg, were assassinated by Bosnian Serb student Gavrilo Princip. This event set off a chain of actions that led to the beginning of World War I. Austria-Hungary, already outraged by Russia's influence in the Balkans, delivered an ultimatum to Serbia, which was bound to be rejected, and when it was, Austria broke off diplomatic relations with Serbia.
Russia mobilized in support of Serbia, and Germany, honouring its alliance with Austria-Hungary, declared war on Russia. This set off a series of counter-mobilizations. On 6 August 1914, Emperor Franz Joseph of Austria-Hungary signed the declaration of war on Russia.
The alliance between Austria-Hungary and Germany, known as the Austro-German Alliance, was formed in 1879. The two powers promised each other support in the case of an attack by Russia and neutrality if either was attacked by another power. The alliance was formed by German Chancellor Otto von Bismarck, who wished to prevent Germany's isolation and preserve peace, as Russia would not wage war against two empires. The addition of Italy in 1882 turned the alliance into the Triple Alliance.
Despite a shared language and similar culture, Austria-Hungary and Germany were often driven apart. The Habsburg rulers believed that Germany's promotion of nationalism would destroy their multinational empire. However, their common distrust of Russia united the two empires. Germany also had plans to create a Mitteleuropa economic association, which would include Austria-Hungary.
During World War I, Italy, a member of the Triple Alliance, did not immediately go to war with its allies but stayed neutral. In 1915, it switched sides and joined the Entente powers, hoping to gain territory from its former allies. Despite this, Germany dispatched reinforcements to aid the faltering Habsburg forces.
