Who assassinated Archduke Franz Ferdinand in 1914?
Gavrilo Princip, who got help from the leaders of The Black Hand. He really got screwed though. They gave him a small capsule of cyanide he could use after killing Franz Ferdinand, so he would get poisoned and die too. In the end it turned out that it was ‘old’ cyanide, therefore it dit not kill him. They never took him seriously from the start, when he came forward to present his plan to them.
