Those two shots set off a chain reaction that dragged nearly every major power into a war that killed roughly 20 million people—World War I.

Many Serbs believed all South Slavs should unite in one nation connected to Serbia, not ruled by a German-speaking emperor in Vienna. Russia, which saw itself as protector of Slavic peoples, objected angrily. But Germany backed Austria-Hungary, and Russia—facing war against two empires at once—backed down. Serbia was humiliated.
