What event sparked World War I?

• A. The assassination of Archduke Franz Ferdinand of Austria
• B. The invasion of Poland by Germany
• C. The sinking of the Lusitania
• D. The Zimmerman Telegram

Answer: (A)

The immediate trigger for World War I was the assassination of Archduke Franz Ferdinand of Austria in Sarajevo in 1914. This single act provided the spark that set off a chain reaction: Austria-Hungary blamed Serbia, issued an ultimatum, and after Serbia’s response, declared war. Because Europe was locked into a web of alliances, mobilizations and declarations followed rapidly—Russia moved to defend Serbia, Germany backed Austria-Hungary, France and Britain became involved, and the conflict expanded across the continent and beyond. The assassination itself didn’t create the long-standing tensions, but it activated them and pulled the major powers into war. The other events aren’t the spark because they occurred after the fighting began or did not initiate the conflict itself. The invasion of Poland started World War II, not World War I. The sinking of the Lusitania influenced public opinion and U.S. sentiment but did not start the war. The Zimmermann Telegram pushed the United States toward involvement, but by that time the war had already started.
