In India, the Parsis are an ethnic and religious minority. With a population of about a million, they are arguably the tiniest community in the whole globe. A native of Pars or Fars is referred to as a Parsi. Southern Iran contains the ancient Persian province of Pars. They departed their nation to protect their faith from being forcibly assimilated by Arab Muslims who invaded their territory in the seventh century A.D. The Parsis are devotees of Zoroaster, also known as Prophet Zarathustra.
