'Land of the Romans';[a] Turkish: Rumeli; Greek: Ρωμυλία) was the name of a historical region in Southeastern Europe that was administered by the Ottoman Empire, roughly corresponding to the Balkans.
The old Latin documents in Genoa use the term Romania, the common name for the Byzantine Empire during the Middle Ages.
The region remained primarily populated by Christians; though gradually, the Albanians, Bosniaks and Pomaks, as well as many Greeks, Serbs, Bulgarians and Vlachs, converted to Islam.
[4] The name "Rumelia" was ultimately applied to a province composed of central Albania and northwestern Macedonia, with Bitola being the main town.
Eastern Rumelia was constituted as an autonomous province of the Ottoman Empire by the Treaty of Berlin (1878),[4] but on September 6, 1885, after a bloodless revolution, it was united with Bulgaria.
