More than 70 million people, including 60 million Europeans, served in the military. This war was also very lethal, with around 9 million military members and 7 million civilians dying.

The murder of Archduke Franz Ferdinand by Gavrilo Princip set off the Great War. Serbia and Austria-Hungary went to war after the murder. A tangle of relationships fueled the escalation of the conflict. The Triple Entente and the Triple Alliance fought each other for control of Europe.

A chain reaction ensued. Russia was prepared to protect Serbia, its ally. Then, to preserve Austria, Germany declared war on Russia. To save Russia, France went to war with Germany. After Germany invaded Belgium, the United Kingdom declared war on Germany.
