The assassination of Archduke Franz Ferdinand of Austria-Hungary on June 28, 1914, triggered the alliance system that ultimately led to World War I. This event ignited existing tensions between major powers and activated a network of alliances, as countries were bound to support each other. Austria-Hungary's declaration of war on Serbia prompted Russia to mobilize in defense of Serbia, leading to the involvement of Germany, France, and Britain, thereby escalating the conflict into a full-scale war. The intricate web of alliances turned a regional dispute into a global conflict.
