Who assassinated Archduke Franz Ferdinand?

Gavrilo Princip assassinated Archduke Franz Ferdinand. He was a member of the Serbian nationalist organization, the Black Hand, and was driven by the desire for Bosnian independence from Austria-Hungary. On June 28, 1914, Princip shot and killed Archduke Franz Ferdinand and his wife during their visit to Sarajevo, Bosnia. This assassination served as the spark that ignited World War I, as it led to a series of diplomatic tensions and eventually the outbreak of war.
