On 28 June 1914, Gavrilo Princip, a Bosnian Serb Yugoslav nationalist, assassinated the Austro-Hungarian heir Archduke Franz Ferdinand in Sarajevo, leading to the July Crisis. In response, on 23 July Austria-Hungary issued an ultimatum to Serbia. Serbia's reply failed to satisfy the Austrians, and the two moved to a war footing.

28 June 1914
World War I
The assassination led to a month of diplomatic manoeuvring between Austria-Hungary, Germany, Russia, France and Britain, called the July Crisis. Austria-Hungary correctly believed that Serbian officials (especially the officers of the Black Hand) were involved in the plot to murder the Archduke, and wanted to finally end Serbian interference in Bosnia. On 23July, Austria-Hungary delivered to Serbia the July Ultimatum, a series of ten demands that were made intentionally unacceptable, in an effort to provoke a war with Serbia. Serbia decreed general mobilisation on 25July. Serbia accepted all the terms of the ultimatum except for article six, which demanded that Austrian delegates be allowed in Serbia for the purpose of participation in the investigation into the assassination. Following this, Austria broke off diplomatic relations with Serbia and, the next day, ordered a partial mobilisation. Finally, on 28 July 1914, a month after the assassination, Austria-Hungary declared war on Serbia.
