Why was the Archduke of Austria being assassinated by the Serbian nationalists the beginning of World War 1?

Answer 1

Archduke Francis Ferdinand, heir to the Austria-Hungarian throne, was killed by Gavrilo Princip, a Serbian Nationalist. Princip killed the Archduke as a way to push Austria-Hungary out of Serbia, which Austria-Hungary had recently occupied. Princip was a member of the Black Hand, a Serbian terrorist organization. Though Princip was not the first assasin to attack the Archduke that day, he was the only one that even wounded him. The Archduke's luck ran out and he was shot at close range. The weapons used by the assassins were traced back to the Serbian government, and Austria-Hungary declared war on Serbia. Serbia was allied with France, and France with Britain and Russia. Austria-Hungary was allied with Germany and the Ottoman Empire (mainly present-day Turkey and Greece. The allies on both sides declared all-out war on each other, and the First World War began. Hope this helps.

Answerthe assasination was pretty much a "trigger" of the war. to some it seems insignificant to the cause of the war. there were many other built up reasons, such as nationalism, militarism, and the alliance system.
