The assassination that triggered World War I happened 102 years ago today - here's the massive scope of that conflict in a single GIF

One hundred and two years ago today, the fate of world history was changed forever.

Austro-Hungarian Archduke Franz Ferdinand, heir to the throne, and his wife were gunned down on the streets of Sarajevo, Bosnia by a Serbian nationalist. The assassination, and the subsequent political and military upheavals, led to the start of World War I and the decimation of large swathes of Europe.

One hundred years after the start of WWI, it is still extremely difficult to comprehend just how global a phenomenon the war was. It affected people on every continent and hastened the end of the European empires.

World War I started off solely as a military conflict between the Austro-Hungarian Empire and Serbia following the killing of Austro-Hungarian Archduke Franz Ferdinand by a Serbian assassin. Through a web of entangling defensive alliances, the conflict quickly morphed into a war that pulled in almost the entirety of the world.

By the time the war ended, the Russian, Ottoman, Austro-Hungarian, and Prussian Empires had collapsed. The war claimed over 37 million lives, and large swathes of Europe lay in complete destruction.

Incredibly, only two decades later the world would be poised on the brink of World War II.
