Today marks the 100th anniversary of the assassination in Sarajevo, Bosnia of Archduke Franz Ferdinand of Austria-Hungary and his wife Sophie. The assassin, Gavrilo Princip, was a Bosnian Serb whose Yugoslav nationalist group Young Bosnia was protesting the 1908 annexation of Bosnia by Austria-Hungary. These killings set off a chain of events which led directly to the war we now call World War One. Taken into custody at the scene, Princip was a few weeks short of his 20th birthday, the minimum age for capital punishment under Austro-Hungarian law. Instead he was given the maximum sentence of 20 years in prison, where he contracted tuberculosis and died in 1918.
