Parsi /ˈpɑrsiː/ (or Parsee) is one of two Zoroastrian communities (the other being Iranis) which are primarily located in India. According to the Qissa-i Sanjan, Parsis originally migrated from Greater Iran to Gujarat and Sindh at some point during the 8th to 10th century to avoid the persecution of Zoroastrians by Muslim invaders who were in the process of conquering Iran.At the time of the Muslim conquest of Persia, the dominant religion of the region was Zoroastrianism.
