Austria-Hungary presents ultimatum to Serbia

On July 23, 1914, Austria-Hungary delivered a ten-point ultimatum to Serbia following the assassination of Archduke Franz Ferdinand in Sarajevo on June 28. The demands included suppression of anti-Austrian organizations on Serbian soil, dismissal of officials Austria-Hungary deemed hostile, and participation of Austro-Hungarian agents in Serbia's internal investigation. Serbia accepted all terms except foreign participation in its judicial proceedings, citing constitutional constraints. Austria-Hungary rejected the response and declared war on Serbia five days later, on July 28.
