After Archduke Franz Ferdinand of Austria was assassinated on June 28, 1914, Austria-Hungary issued an ultimatum to Serbia, which contained demands that were intentionally harsh. Serbia's response was deemed insufficient, leading Austria-Hungary to declare war on Serbia on July 28, 1914. This conflict quickly escalated, as alliances were activated, resulting in the outbreak of World War I, involving many of the world's great powers. The war would last until 1918, leading to significant geopolitical changes and the eventual collapse of empires.
