Franz Ferdinand's assassination

The assassination of Archduke Franz Ferdinand of Austria-Hungary occurred on June 28, 1914, in Sarajevo. Gavrilo Princip, a young Serbian nationalist, shot and killed him during a parade to promote peace. This event heightened tensions between Austria-Hungary and Serbia, as Ferdinand's assassination was seen as an attack by Serbian nationalists. Consequently, Austria-Hungary issued demands to Serbia, leading to a declaration of war. This chain of events triggered World War I, involving many nations and lasting for over four years. The assassination is widely considered the spark that ignited the conflict.
