World War I began in 1914 after which event?

• A. The assassination of Archduke Franz Ferdinand.
• B. The invasion of Belgium.
• C. The sinking of the Lusitania.
• D. The Zimmerman Telegram.

Answer: (A)

This question is about the trigger that started World War I and how a regional crisis spiraled into a global conflict through alliances. The assassination of Archduke Franz Ferdinand, heir to the Austro-Hungarian throne, in Sarajevo in 1914 provided the immediate spark. Austria-Hungary’s retaliation against Serbia set off a cascade of mobilizations and declarations of war among allied powers, pulling in Russia, Germany, France, and Britain and turning a local feud into a continental war. Events like the invasion of Belgium, the sinking of the Lusitania, and the Zimmerman Telegram were significant during the war, but they occurred after fighting began and did not start the conflict.
