Seven young men were charged with the murder of Archduke Franz Ferdinand, heir to the Austro-Hungarian throne, whose death triggered the First World War. Six were under 20 years old, the legal age of the death penalty in the Austrian Empire. The seventh, Danilo Ilic, was 24.

Ilic, a Serb, had attempted to save his life by denouncing his six fellow-conspirators to the police. All seven were convicted by a Sarajevo military court on October 23rd, 1914. Ilic was hanged in Sarajevo Prison on Wednesday, February 3rd, 1915. The other six were sentenced to 20 years each and all of them died in prison before the end of the war they had started.
