What happened after the assassination of Archduke Franz Ferdinand that led to World War l

The causes of World War I, also known as the Great War, have been debated since it ended. Officially, Germany shouldered much of the blame for the conflict, which caused four years of unprecedented slaughter. But a series of complicated factors caused the war, including a brutal assassination that propelled Europe into the greatest conflict the continent had ever known.

The murder of Archduke Franz Ferdinand outraged Austria-Hungary.

In June 1914, Austrian Archduke Franz Ferdinand and his wife Sophie traveled to Bosnia-which had been annexed by Austria-Hungary-for a state visit.

On June 28, the couple went to the capital city of Sarajevo to inspect imperial troops stationed there. As they headed toward their destination, they narrowly escaped death when Serbian terrorists threw a bomb at their open-topped car.
