New Delhi, July 28: In late June 1914, Archduke Franz Ferdinand of Austria was assassinated by a Serbian nationalist in Sarajevo, Bosnia.
An escalation of threats and mobilization orders followed the incident, leading to the outbreak of World War I on July 28, which pitted Germany, Austria-Hungary and the Ottoman Empire against Great Britain, France, Russia, Italy and Japan.

By the time World War I ended in the defeat of the Central Powers in November 1918, more than 9 million soldiers had been killed and 21 million more wounded.
