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.
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.
Edirne is an electoral district of the Grand National Assembly of Turkey. It elects three members of parliament (deputies) to represent the province of the same name for a four-year term by the D'Hondt method, a party-list proportional representation system.
Population reviews of each electoral district are conducted before each general election, which can lead to certain districts being granted a smaller or greater number of parliamentary seats. Edirne's seats were reduced from four to three in 2011.
