Gavril Princip, a 20-year-old Serbian nationalist, acted alone when he shot the Austrian Crown Prince, Archduke Franz Ferdinand along with his morganatic wife Sophie, Sarajevo 12 August, 1914. The Archduke's last words were "It is nothing" before collapsing onto his already dead wife.

Gavrilo Princip, a member of the Serbian nationalist group known as the Black Hand, assassinated Archduke Franz Ferdinand and his wife, Sophie, in Sarajevo on June 28, 1914.
