The assassination of Archduke Franz Ferdinand of
Austria-Hungary on June 28, 1914, in Sarajevo, Bosnia, served

military mobilizations and alliances. Russia, which had pledged

Austria-Hungary's actions.

now at war, the conflict quickly escalated into a wider
conflagration. The alliance system and pre-existing rivalries
