Gavrilo Princip (, ; 25 July 189428 April 1918) was a Bosnian Serb member of Young Bosnia who sought an end to Austro-Hungarian rule in Bosnia and Herzegovina. At the age of 19, he assassinated Archduke Franz Ferdinand of Austria and the Archduke's wife, Sophie, Duchess of Hohenberg, in Sarajevo on 28 June 1914. Princip and his accomplices were arrested and implicated as members of a nationalist secret society, aiming to remove Habsburg colonial rule, which initiated the July Crisis and led to the outbreak of World War I.
