Austria-Hungary's Documents: The Spark Of World War I

The assassination of Archduke Franz Ferdinand of Austria and his wife by a Serbian nationalist in Sarajevo on 28 June 1914 was the catalyst for World War I. Austria-Hungary declared war on Serbia on 28 July 1914, after 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. This declaration of war effectively began World War I, as Russia mobilised in support of Serbia, setting off a series of counter-mobilisations.

The July Ultimatum

Serbia accepted nine of the ten demands but only partially accepted the remaining one, which infringed upon its rights as a sovereign state. In response, Austria-Hungary declared war on Serbia on 28 July 1914, effectively beginning the First World War.

The assassination of Archduke Franz Ferdinand

Austria-Hungary, backed by Germany, used the assassination as an excuse to confront Serbia militarily before it could incite a revolt. On 28 July 1914, one month after the assassination of the Archduke, Austria-Hungary declared war on Serbia, effectively beginning World War I. Over the course of July and August 1914, these events caused the start of the war, as Russia mobilized in support of Serbia, setting off a series of counter-mobilizations. On 6 August 1914, Emperor Franz Joseph signed the declaration of war on Russia, with Italy initially remaining neutral, despite its alliance with Austria-Hungary.

The Serbian nationalist movement

Following the assassination, Austria-Hungary presented Serbia with an ultimatum on 23 July 1914, demanding the suppression of anti-Austrian propaganda and the right to conduct its own investigation into the archduke's killing. Serbia partially accepted the ultimatum, but Austria-Hungary was not satisfied and declared war. This declaration of war was supported by Germany, Austria-Hungary's ally.

The mobilisation of Russia in support of Serbia

Russia, which had a long-standing alliance with Serbia, began to mobilise its troops in support of Serbia. This mobilisation set off a series of counter-mobilisations, as other European powers began to take sides. On 6 August 1914, Emperor Franz Joseph of Austria-Hungary, backed by Germany, signed a declaration of war on Russia. This marked the official start of World War I, as the conflict escalated beyond the Balkans and drew in the major powers of Europe.

The mobilisation also highlighted the complex web of alliances that existed in Europe at the time. Russia was allied with France, which in turn had an understanding with Britain. This meant that the conflict now involved three of the major powers in Europe, with Germany and Austria-Hungary on one side and Russia, France, and Britain on the other. The mobilisation of Russia thus set in motion a chain of events that ultimately led to the outbreak of World War I.

In conclusion, the mobilisation of Russia in support of Serbia was a pivotal moment in the lead-up to World War I. It demonstrated the fragility of the European alliance system and the interconnectedness of the continent's powers. Russia's mobilisation was a direct response to Austria-Hungary's aggression towards Serbia, and it set off a series of counter-mobilisations that ultimately escalated the conflict into a global war.

The declaration of war on Russia

Austria-Hungary had presented Serbia with an ultimatum on 23 July 1914, demanding that all anti-Austrian propaganda within Serbia be suppressed, and that Austria-Hungary be allowed to conduct its own investigation into the assassination of Archduke Franz Ferdinand. Serbia accepted nine of the ten demands, but only partially accepted the remaining one. This led to Austria-Hungary declaring war on Serbia on 28 July 1914, effectively beginning the First World War.

Russia's mobilisation in support of Serbia set off a series of counter-mobilisations, and Italy initially remained neutral, despite its alliance with Austria-Hungary.
