Serbia (Triple Entente vs. Central Powers Map Game)

The  Kingdom of Serbia ( Serbian:  Краљевина Србија / Kraljevina Srbija ) was created when Prince  Milan Obrenović, ruler of the Principality of Serbia, was crowned king in 1882. The  Principality of Serbia was ruled by the  Obrenović dynasty from 1817 onwards (at times replaced by the  Karađorđević dynasty). The Principality,  suzerain to the  Porte, had expelled all  Ottoman troops by 1867, de facto securing its independence. The  Congress of Berlin in 1878 recognized the formal independence of the  Principality of Serbia.

Principality of Serbia
The Principality of Serbia was a state in the Balkans that came into existence as a result of the Serbian revolution which lasted between 1804 and 1817. Despite brutal oppression and retaliation by the Ottoman authorities, the revolutionary leaders, first Karađorđe and then Miloš Obrenović, succeeded in their goal to liberate Serbia after centuries of Turkish rule.
