Sophie, Duchess of Hohenberg
In Europe the assassination of Archduke Franz Ferdinand by Gavrilo Princip, one of several Serb nationalist insurgents, triggered World War I. Archduke Franz Ferdinand was visiting Bosnia-Herzegovina, since it was newly annexed to the Austro-Hungarian Empire. He had a route through the city streets of Sarajevo, Bosnia, but was redirected to a back alley. He changed his course and as he was led around the corner out of the back alley and back onto the main street, Gavrilo Princip shot Franz Ferdinand and his wife (Sophie, Duchess of Hohenberg). This assassination brought the Austro-Hungarian Empire into a state of outrage and therefore, World War I was triggered.
