Gavrilo Princip (Serbian Cyrillic: Гаврило Принцип) (July 25, 1894 April 28, 1918) was a Bosnian Serb nationalist who killed Franz Ferdinand, Archduke of Austria, and his wife Countess Sophie in Sarajevo on June 28, 1914. The event, known as the assassination in Sarajevo, prompted the Austrian action against Serbia that led to World War I.
Early Life Born in Obljaj, Bosansko Grahovo, Bosnia and Herzegovina. Gavrilo Princip's parents, Petar and Marija Nana Mičić, had nine children, five sons and four daughters, six of whom died in infancy. His health was poor. From an early age, he suffered from tuberculosis, which was his eventual cause of death in 1918, and was also one of the reasons he let himself kill Archduke Ferdinand in the first place.
Princip attended primary school in Grahovo where he excelled in his studies, especially in romantic and historic literature. A teacher at the school gave him a collection of Serbian heroic folk poetry. At thirteen, Princip planned on a military career and went to Sarajevo to study at the Military School. After arriving, he instead chose to pursue a business career so he enrolled in the Merchant's School where he studied for three years.
Contrary to common belief, Princip was not a member of the Black Hand, but was a member of the group Young Bosnia (Mlada Bosna), which he joined in 1911. The Young Bosnia Movement was a group made up of Serbs, Croats, and Bosnian Muslims, committed to achieving independence for Bosnia.
