Млада Босна
On Vidovdan in 1914, Gavrilo Princip, the Bosnian Serb member of Young Bosnia, assassinated Archduke Franz Ferdinand of Austria which initiated the July Crisis and led to the outbreak of World War I. Princip, Nedeljko Čabrinović and other members of the Young Bosnia were inspired by the heroism of Miloš Obilić, reenacting the Kosovo Myth. Princip knew the entire Njegoš's "The Mountain Wreath".
