Edirne
Edirne (Turkish pronunciation: [eˈdiɾne]), historically known as Adrianople, is a city in the northwestern Turkish province of Edirne, in the region of East Thrace, close to Turkey's borders with Greece and Bulgaria. Edirne served as the third capital city of the Ottoman Empire from 1363 to 1453, before Constantinople (present-day Istanbul) became the empire's fourth and final capital. At present, Edirne is the capital of Edirne Province in Turkish Thrace. The city's estimated population in 2014 was 165,979.
Etymology
The city was founded as Hadrianopolis (Aδριανούπολις in Greek), named for the Roman Emperor Hadrian. This name is still used in the Modern Greek (Αδριανούπολη). The name Adrianople was used in English, until the Turkish adoption of Latin alphabet in 1928 made Edirne the internationally recognized name. The Turkish: Edirne, Bulgarian: Одрин (Odrin, ['odrin]), Albanian: Edrêne, Macedonian: Eдрене (Edrene) and Serbian: Једрене / Jedrene are adapted forms of the name Hadrianopolis or of its Turkish version; see also its other names.
