Eastern Rumelia

Eastern Rumelia (Bulgarian: Източна Румелия, romanized: Iztochna Rumeliya; Ottoman Turkish: روم‌ایلی شرقی ولایتی, romanized: Rumeli-i Şarkî Vilayeti; Greek: Ανατολική Ρωμυλία, romanized: Anatoliki Romylia) was an autonomous province (oblast in Bulgarian, vilayet in Turkish) of the Ottoman Empire with a total area of 32,978 km2 (12,733 sq mi), which was created in 1878 by virtue of the Treaty of Berlin and de facto ceased to exist in 1885, when it was united with the Principality of Bulgaria, also under nominal Ottoman suzerainty. It continued to be an Ottoman province de jure until 1908, when Bulgaria declared independence. Ethnic Bulgarians formed a majority of the population in Eastern Rumelia, but there were significant Turkish and Greek minorities. Its capital was Plovdiv (Ottoman Filibe, Greek Philippoupoli). The official languages of Eastern Rumelia were Bulgarian, Greek and Ottoman Turkish.
