The Parsis or Parsees are an ethnoreligious group of the Indian subcontinent adhering to Zoroastrianism. They are descended from Persians who migrated to Medieval India during and after the Arab conquest of the Persian Empire to escape religious persecution. Parsis are the older of the Indian subcontinent's two Zoroastrian communities, the other being the Iranis, whose ancestors migrated to British-ruled India from Qajar-era Iran. According to a 16th-century Parsi epic, Qissa-i Sanjan, Zoroastrian Persians continued to migrate to the Indian subcontinent from Greater Iran in between the 8th and 10th centuries, and ultimately settled in present-day Gujarat after being granted refuge by a local Hindu king, Jadi Rana.
