See it on the Battles & Wars map →What happened
On June 28, 1914, Archduke Franz Ferdinand and his wife Sophie visited Sarajevo, capital of Bosnia, which Austria-Hungary had annexed in 1908. Six young conspirators lined the route, armed with help from the Black Hand, a secret Serbian nationalist society run by army officers. A bomb missed. Later the archduke's car took a wrong turn and stopped near 19-year-old Gavrilo Princip, who shot both dead. Austria-Hungary, backed by Germany, blamed Serbia.
Why it matters
Austria-Hungary's ultimatum to Serbia set the alliance system in motion; by early August 1914 Europe's great powers were at war.
How we know
Trial records of Princip and his fellow conspirators, police reports, eyewitness accounts and photographs. The car and the archduke's bloodstained uniform are displayed in Vienna's Museum of Military History.
Still debated
How much Serbia's government knew in advance is debated; Prime Minister Nikola Pašić may have heard of the plot and sent only a vague warning.
Connections (2)
▸Assassination of Archduke Franz Ferdinand triggered World War IWell documented
The connection
Austria-Hungary used the killing to try to crush Serbia. With Germany's promise of support (the 'blank check'), it sent Serbia an ultimatum and declared war on July 28. Russia mobilized to protect Serbia; Germany declared war on Russia and France and invaded Belgium; Britain entered on August 4.
When and how
Vienna, Berlin, St Petersburg, Paris and London during the 'July Crisis', between June 28 and August 4, 1914.
How we know
Diplomatic telegrams and cabinet papers from every capital, published after the war, document each step of the July Crisis.
Debates and open questions
Who bears most responsibility is a century-old debate: German ambition (Fritz Fischer's thesis), Austrian and Russian choices, or a shared 'sleepwalking' (Christopher Clark).
▸Assassination of Archduke Franz Ferdinand served a South Slav dream that ended in Yugoslav WarsMostly agreed
The connection
Princip and his group, Young Bosnia, wanted to free the South Slavs from Austria-Hungary and unite them. That dream came true in 1918 with the Kingdom of Serbs, Croats and Slovenes, later Yugoslavia. Rival national claims within it, held down under Tito's communist rule, erupted when Yugoslavia broke apart in 1991, bringing wars in Croatia, Bosnia and Kosovo.
When and how
Sarajevo, 1914; Yugoslavia founded December 1, 1918; its breakup began with Slovenia's and Croatia's declarations of independence in June 1991.
How sure are we?
Princip's trial testimony states his Yugoslav aims. The link to the 1990s is a long arc, mostly agreed, rather than a direct cause.
Debates and open questions
Princip is remembered very differently: a liberation hero to many Serbs, an assassin or terrorist to many others. Whether Yugoslavia was doomed from the start is debated.
