Edirne was originally part of Eastern Thrace and was known as Uskadama or Uskudama. The city was rebuilt by the Roman emperor Hadrian about ad125 and renamed Hadrianopolis. It was the focal point of the Battle of Adrianople (ad378), in which the Romans under Emperor Valens were defeated by the Goths. Edirne was then conquered successively by the Avars, the Bulgarians, and the Crusaders (see Crusades). In 1361 the Ottoman Turks gained control of the city, and the Ottoman sultans lived here until 1453; during this period the city served as European capital of the Ottoman Empire. Edirne constantly changed hands during the Russo-Turkish wars of 1828-1829 and 1877-1878, and also during the Balkan Wars (1912-1913). Population (1990) 102,345.
