What happened in July 1914 that encouraged austria Hungary to set a 48 hour deadline?

Answer 1

In July 1914, following the assassination of Archduke Franz Ferdinand of Austria by a Bosnian Serb nationalist, Austria-Hungary sought to address perceived threats from Serbia. The situation escalated when Austria-Hungary issued an ultimatum to Serbia, which included demands that were difficult for Serbia to accept fully. The 48-hour deadline was set to pressure Serbia into compliance, while also demonstrating Austria-Hungary's resolve to take military action if necessary, ultimately contributing to the outbreak of World War I.
