Expulsion of the Albanians (1877–1878)

The expulsion of the Albanians (1877–1878) refers to events of forced migration of Albanian populations from areas that became incorporated into the Principality of Serbia and Principality of Montenegro in 1878 after their initial expulsion from 1830 to 1876. These wars, alongside the larger Russo-Ottoman War (1877–78) ended in defeat and substantial territorial losses for the Ottoman Empire which was formalised at the Congress of Berlin.
