Ankara is the capital city of Turkey. Located in the central part of Anatolia, the city has a population of over 5.3 million residents in its urban center, out of 6 million residents in Ankara Province . Ankara is Turkey's second-largest city by population after Istanbul.
Ankara was historically known as Ancyra and Angora. Serving as the capital of the ancient Celtic state of Galatia (280–64 BC), and later of the Roman province with the same name (25 BC–7th century), Ankara has various Hattian, Hittite, Lydian, Phrygian, Galatian, Greek, Persian, Roman, Byzantine, and Ottoman archeological sites. The Ottomans made the city the capital of the Anatolia Eyalet (1393 – late 15th century), the Angora Eyalet (1827–1864), and the Angora Vilayet (1867–1922).
