Grave of Gavrilo Princip, Sarajevo cemetery, Bosnia-Hercegovina, Yugoslavia, 1939. Gavrilo Princip (1894-1918), a Yugoslav nationalist, assassinated Archduke Franz Ferdinand of Austria in Sarajevo on 28 June 1914, setting in motion the chain of events that would lead to the outbreak of the First World War. Princip unsuccessfully attempted to commit suicide after the assassination and was captured by the authorities. As he was under the age of 20, he was too young to receive the death penalty and was therefore sentenced to 20 years in prison, the maximum sentence. Princip contracted tuberculosis while in jail and died in 1918.
