Восточная Румелия
Eastern Rumelia (, "Iztochna Rumeliya"; , "Rumeli-i Şarkî"; , "Anatoliki Romylia") was an autonomous province ("oblast" in Bulgarian, "vilayet" in Turkish) in the Ottoman Empire, created in 1878 by the Treaty of Berlin and "de facto" ended in 1885, when it was united with the Principality of Bulgaria, also under 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.
