The assassination of Archduke Franz Ferdinand of Austria in June 1914 is widely recognized as the spark that ignited World War I. This unexpected event set off a chain reaction of alliances and hostilities among major powers, resulting in a global conflict that would reshape nations and alter history. When the United States entered World War I in 1917, it was mainly driven by Germany's unrestricted submarine warfare, which threatened American ships and lives. Additionally, the interception of the Zimmerman Telegram, in which Germany proposed a military alliance with Mexico against the U.S., fueled public outrage and a desire to join the fight for democracy and against tyranny.
