Casualties and Losses

The July Crisis (known in western Europe as July's War) was a minor war in western European (mainly Austria-Hungary) lasting from 28 July 1914 until 29 August 1914. The war was on the verge of becoming a major war, until the coalition powers as well as protests crippled the Austro-Hungarian Empire.


On 28 June, Archduke Franz Ferdinand of Austria had been assassinated while in Sarajevo by Gavrilo Princip, from a group of six Bosnian Serb assassins coordinated by Danilo Ilić. The assassination caused outrage from Austro-Hungarians, who had talks of declaring war on Serbia. The Austro-Hungarian government discussed what to do with the situation, many wanting to avoid war with the powerful Great Alliance. Many government officials (as well as Germany, one of Austro-Hungary's allies) wanted to create an ultimatum for the Serbians that the Alliance would sympathize with, while others wanted full-out war with the Serbians. By July, the ultimatum was made, which many of the demands the Great Alliance agreed with. Russia and the United Kingom urged the Serbian government to agree to the terms to avoid war. Ultimately, of ten, Serbia only agreed to eight demands. Many Austro-Hungarians urged the government to accept the Serbian's compliance with eight demands, however the final decision was war.
