World War I

Explanation:

The assassination of Archduke Franz Ferdinand was the trigger incident that caused World War I. He was the heir to the Austro-Hungarian throne, thus a very important person. When he was visiting Sarajevo in June 1914, he was assassinated by a Serbian nationalist (Gavrilo Princip).

Austria-Hungary gave Serbia an ultimatum (a list of very serious demands). Serbia did not accept the ultimatum because it interfered with its sovereignty, in particular the clause that allowed for officials from Austria-Hungary to investigate.

After a month, Austria-Hungary declared war on Serbia, which brought all of the alliances for Austria-Hungary and Serbia to go to war as well.

Although there are many indirect causes for WWI, including militarism, alliances, imperialism and nationalism, this is considered the direct cause.
