The assassination of Archduke Franz Ferdinand of Austria, heir presumptive to the Austro-Hungarian throne, took place on June 28, 1914, in Sarajevo, Bosnia and Herzegovina. The assassination was carried out by a Bosnian Serb nationalist named Gavrilo Princip, who was a member of a group known as the Black Hand.

The assassination of Archduke Ferdinand was a key event that led to the outbreak of World War I. Austria-Hungary saw the assassination as a direct attack on their sovereignty and declared war on Serbia. The alliance system in Europe then kicked in, with other countries being drawn into the conflict. Within weeks, the world was at war.

There were already existing tensions between Austria-Hungary and Serbia, as Serbia sought to create a pan-Slavic state that would include Bosnia and Herzegovina, which were then part of the Austro-Hungarian Empire. The assassination of Archduke Ferdinand provided Austria-Hungary with the excuse they needed to take action against Serbia.

The assassination also highlighted the growing nationalist and anti-Austrian sentiment among the various ethnic groups in the Balkans, including the Serbs, Croats, and Bosniaks. These tensions had been building for years, and the assassination of Archduke Ferdinand was the spark that set off the powder keg.

After the assassination of Archduke Franz Ferdinand in Sarajevo in June 1914, Austria-Hungary became convinced that Serbia was behind the attack and sought to punish the country. On July 23, 1914, Austria-Hungary presented Serbia with an ultimatum that contained a list of demands. The ultimatum demanded that Serbia take measures to suppress anti-Austrian propaganda, arrest and punish certain individuals involved in the assassination plot, and allow Austro-Hungarian officials to participate in the investigation of the assassination.

The ultimatum was seen by many as an infringement on Serbia's sovereignty, and Serbia initially rejected some of the demands. However, Serbia eventually agreed to most of the demands within the 48-hour time limit set by Austria-Hungary, hoping to avoid war.

Germany, Austria-Hungary's ally, supported Austria-Hungary in presenting the ultimatum to Serbia. Germany had a strong interest in maintaining the balance of power in Europe and saw Serbia as a threat to that balance. Germany also saw an opportunity to demonstrate its loyalty to Austria-Hungary, which it viewed as a key ally in the region.

The ultimatum was a key event that ultimately led to the outbreak of World War I. Austria-Hungary was not satisfied with Serbia's response and declared war on Serbia on July 28, 1914. The alliance system in Europe then kicked in, with other countries being drawn into the conflict, leading to a global war that lasted for four years.
