Serbia's Actions: Austria-Hungary's Fury

Serbia and Austria-Hungary had a hostile relationship between 1878 and 1914. Austria-Hungary was fearful of Serbian growth and expansion in the Balkans, and Serbia felt that Austria-Hungary was thwarting its attempts to gain land in the region. Serbia's growing alliance with Russia also worried Austria-Hungary, who responded by annexing Bosnia-Herzegovina in 1908. This angered Serbia, who wanted Bosnia-Herzegovina under their control. The results of the Balkan Wars also contributed to the hostility between the two countries, with Serbia gaining control of the Adriatic coastline and Albania, which Austria-Hungary resented and feared.

Serbia's growing power and influence in the Balkans

Serbia's ambitions in the Balkans region, which was already tumultuous, were seen as a threat by Austria-Hungary. In 1908, Austria-Hungary annexed Bosnia-Herzegovina, which angered Serbia as they had wanted control of that region. This was the first of several instances where Serbia felt that their gains of land in the Balkans were being thwarted by Austria-Hungary.

Serbia's success in the Balkan Wars further increased tensions. After the first Balkan War in 1912, Serbia gained control of the Adriatic coastline and took over Albania. This sudden growth worried Austria-Hungary, who wanted Serbia to give up these newly acquired territories. Serbia's alliance with Russia, who supported their expansion, further angered Austria-Hungary, leading to the mobilisation of troops on both sides.

Serbia's continued territorial gains in the Balkans, such as their victory over Bulgaria in 1913, which resulted in Serbia acquiring parts of Macedonia, only served to heighten Austria-Hungary's fears. By 1914, Austria-Hungary was convinced that offensive action against Serbia was necessary to protect the integrity of their empire.

The assassination of Archduke Franz Ferdinand of Austria and his wife by a Serbian nationalist in Sarajevo in 1914 provided the final spark. Austria-Hungary presented Serbia with an ultimatum, demanding the suppression of anti-Austrian propaganda and the right to conduct their own investigation into the archduke's killing. When Serbia failed to apologise or comply with these demands, Austria-Hungary, with the support of Germany, declared war on Serbia on July 28, 1914, marking the start of World War I.

Austria-Hungary's annexation of Bosnia-Herzegovina

The Second Balkan War in 1913 also played a key role in the hostility between the two countries. Serbia and Greece went to war with Bulgaria to win land they believed they deserved after the first war. Serbia and Greece emerged victorious, capturing parts of Macedonia. Austria-Hungary contemplated military action against Serbia in February and October 1913 but failed to secure the support of Italy or Germany. By supporting Bulgaria's claims against Serbia, Austria-Hungary also alienated Romania, which joined Serbia in supporting irredentist movements within the Habsburg monarchy.

The assassination of Archduke Franz Ferdinand of Austria and his wife by a Serbian nationalist in Sarajevo in 1914 further heightened tensions. Austria-Hungary declared war on Serbia one month after the assassinations, presenting Serbia with an ultimatum demanding the suppression of anti-Austrian propaganda and the right to conduct its own investigation into the archduke's killing. Serbia's refusal to apologise for the assassinations and its perceived intransigence in meeting Austria-Hungary's demands contributed to the growing anger and hostility between the two nations.

The complex dynamics between Austria-Hungary and Serbia, marked by territorial disputes, competing ambitions, and shifting alliances, set the stage for escalating tensions and ultimately, the outbreak of World War I. The annexation of Bosnia-Herzegovina was a pivotal event that fuelled Serbia's resentment and set in motion a series of events that would have far-reaching consequences for Europe and the world.

Serbia's gains in the First Balkan War

Serbia angered Austria-Hungary by gaining control of the Adriatic coastline and Albania after the First Balkan War in 1912. Austria-Hungary feared Serbia's growth and wanted them to give up the land they had gained.

Serbian irredentist movements

In 1908, Austria-Hungary annexed Bosnia-Herzegovina, a move that angered Serbia as they had wanted control of the region themselves. This was followed by the First Balkan War in 1912, which resulted in Serbia gaining control of the Adriatic coastline and taking over Albania. Once again, this angered Austria-Hungary, which resented Serbia's growing power and wanted it to give up its newly acquired territories.

The Second Balkan War in 1913 further exacerbated tensions between the two countries. Serbia and Greece went to war with Bulgaria to win land they felt they deserved after the first war. Serbia and Greece emerged victorious and secured parts of Macedonia in the Treaty of Bucharest. Austria-Hungary's support for Bulgaria's claims against Serbia also alienated Romania, which joined Italy and Serbia in supporting irredentist movements within the Habsburg monarchy.

By 1914, leading government circles in Vienna were convinced that offensive action against Serbia was necessary to protect the integrity of the empire. On July 28, 1914, one month after the assassination of Archduke Franz Ferdinand of Austria by a Serbian nationalist, Austria-Hungary declared war on Serbia, marking the beginning of the First World War.

The assassination of Archduke Franz Ferdinand

The two countries had a long history of tension and hostility, which was largely driven by fears of Serbian expansionism and Austria-Hungary's determination to thwart Serbian territorial gains. In 1908, Austria-Hungary annexed Bosnia-Herzegovina, which angered the Serbs as they wanted control of this region. The results of the Balkan Wars also contributed to the hostility, with Serbia gaining control of the Adriatic coastline and Albania in 1912, and winning parts of Macedonia in 1913. This led to fears in Austria-Hungary about the growth of Serbia and its ambitions in the Balkans region.

Austria-Hungary demanded that Serbia suppress anti-Austrian propaganda and allow them to conduct their own investigation into the Archduke's killing. When Serbia refused to apologise or comply with these demands, Austria-Hungary, with the support of Germany, declared war.
