The city has a 3000 year long history, dating back to the time of the Median empire, when it was known as Ysatis (or Issatis). The present city name, however, may have been derived from Yazdegerd I, a Sassanid ruler. The city was definitely a Zoroastrian centre during Sassanid times. After the Islamic conquest of Persia, many Zoroastrians fled to Yazd from neighbouring provinces. The city remained Zoroastrian even after the conquest by paying a levy, and only gradually did Islam come to be the dominant religion in the city.
