Austria-Hungary delivers an ultimatum to Serbia

On 23 July 1914 the government of Austria-Hungary took a step that openly carried the July Crisis into a new phase: an ultimatum to Serbia was delivered in Belgrade. The document was handed over by the Austro-Hungarian representative, Baron Wladimir Giesl von Gieslingen, and set a deadline for a reply of just 48 hours. The very shortness of that deadline was already a signal that this was not an ordinary exchange of diplomatic notes, but an attempt to force a swift and humiliating capitulation or to create a pretext for war.

The ultimatum was worded so that Serbia could accept some of the demands only at the cost of its own independence. Vienna demanded, among other things, the suppression of anti-Austrian propaganda, the removal of named officials and officers, and the participation of Austro-Hungarian representatives in proceedings conducted on Serbian territory. It was this last element that struck hardest at the country’s sovereignty, since it meant consenting to foreign interference in Serbia’s internal police and judicial apparatus.

Formally, the ultimatum was presented as a response to the assassination in Sarajevo and the supposed need to punish a state that had allegedly tolerated or supported anti-Habsburg activity. The problem, however, was that the Austro-Hungarian investigation had not produced clear proof that the Serbian government had been directly involved in organising the assassination. That is why even contemporary observers saw that the note had been drawn up less as an instrument for obtaining justice and more as a tool of political pressure leading to armed conflict.

The timing of the delivery was not accidental either. The ultimatum was handed over only after the French leaders had ended their visit to Russia, which was meant to hinder a swift and coordinated diplomatic response from Paris and St Petersburg. Vienna and Berlin hoped that the conflict could be presented as a local dispute between Austria-Hungary and Serbia, and that the other powers would be faced with a fait accompli. In practice the opposite happened: 23 July was the day on which the European capitals realised that the situation was slipping out of control.

For this reason the delivery of the ultimatum to Serbia is regarded as one of the most important moments of the entire July Crisis. After 23 July the debate was no longer only about guilt for the assassination or the extent of diplomatic pressure. From then on Europe began counting down to Belgrade’s reply, knowing that peace or war might depend on what it said.
