On June 28, 1914, Archduke Franz Ferdinand of Austria and his wife Sophie were assassinated in Sarajevo by Gavrilo Princip, a member of a nationalist group. This event set off a chain reaction of alliances and conflicts that led to the outbreak of World War I.

Franz Ferdinand was the heir to the Austro-Hungarian throne, and his assassination alarmed European powers, particularly Austria-Hungary and Serbia. The location, Sarajevo, had been a hotspot for nationalist tensions preceding the incident.

Public sentiment quickly turned against Serbia, leading to Austria-Hungary declaring war, which then escalated into a global conflict. The assassination ignited existing tensions between major powers in Europe, greatly changing the geopolitical landscape.

Following the event, various nations mobilized rapidly, and within weeks, several countries were drawn into the war. This incident highlighted how a single act could catalyze widespread instability and conflict.

The assassination is often pointed to as a triggering factor of World War I, leading to approximately 16 million deaths. It marked the start of a period known as the 'Great War', which had far-reaching consequences.

Princip, the assassin, was only 19 years old and acted out of a desire for Yugoslav independence. Historians spotlight how his motivations resonate with many independence movements throughout history.
