Serbia

Serbia is a small country in Eastern Europe. It borders Austria-Hungary and Russia.

In 1914, a Serb assassinated Austro-Hungarian Archduke Franz Ferdinand in Sarajevo. Austria-Hungary made a series of fourteen ultimata against the Serbian government. Russia, a traditional ally of Serbia, promised to support the small nation in a war against Austria-Hungary, and Serbia was emboldened to reject six of the fourteen ultimata. Germany and the United States supported Austria-Hungary against Serbia, Russia, and the rest of the Entente, and the Great War began with Serbia as a minor ally of the Entente.
