Cappadocia fell under the sovereignty of the Kingdom of Lydia in the 6th century B.C and remained so until Croesus, the king of Lydia, was defeated by the Persians. As a result, Cappadocia was ruled by the Persians between the 6th century B.C and the arrival of Alexander the Great in Anatolia. The Persians divided Anatolia into provinces each one of which was ruled by a governor, called a “satrap”. The governance of the Persians was mild and tolerant, and they managed to establish friendly relationships with the local population. The main source of revenue of the Persian economy was the famous King’s Road which, starting from Ephesos and Sardes, ran through Mazaka (Kayseri) and going over Mesopotamia, reached the Persian capital of Susa. The Satraps used to send gold, sheep, mules, and the famous horses of Cappadocia as tax to Persia. The Persians who were fire worshippers must have liked this volcanic area very much, and have found it suitable for their animistic traditions.
