Ankara, formerly known as Ancyra and Angora, is the capital of the Republic of Turkey. The city history can be traced back to the Bronze Age Hattic civilization, which was succeeded in the 2nd millennium BC by the Hittites, in the 10th century BC by the Phrygians, and later by the Lydians, Persians, Greeks, Galatians, Romans, Byzantines, Seljuk Sultanate of Rûm and the Ottoman Empire.
