Zoroastrianism in India

The comparatively liberal atmosphere of India and the protection provided by historical Indian kingdoms to their Zoroastrian subjects enabled the religion to flourish outside of the Iranian plateau. Today, India is home to the largest Zoroastrian population in the world, and despite their overall low population number, Indian Zoroastrians have had a significant influence on India's economy, culture, politics and military, and also played a major role in the Indian independence movement.

History

By 632 CE, Yazdegerd III came to power in Persia but the Arab/Muslim army had already begun invading Persia. The Muslims defeated them at Nahavand and Yazdegerd was slain by a miller in Merv in 652, bringing an end to the Sasanian dynasty and with it Zoroastrianism's history as the official religion of Iran. While losing their religion and script along with some Sasanian historiographical literature, the language and culture essentially survived. Between the seventh and thirteenth century, political and social pressures resulted in ascendancy of Iranian Muslim over the Zoroastrians. With the conquests, Iranians gradually lost their predominant religion.

The Zoroastrians moved to India in successive migrations in the Islamic period. The initial migration following the conquest has been characterized as a religious persecution by invading Muslims. According to the account, the Zoroastrians suffered at their hands and in order to protect themselves and safeguard their religion, fled first to northern Iran, then to the island of Hormuz and finally to India. This generally accepted narrative of migration emphasises Muslim persecution while identifying Parsis as religious refugees. Recently, scholars have questioned this explanation of Iranian origins. There is a scarcity of sources about the migration. Historians are forced to rely exclusively on Qissa-i Sanjan written in 1599 by a Parsi Priest and Qissah-ye Zartushtian-e Hindustan written more than 200 years later. This is complicated by the fact that there were already Zoroastrians in India in the Sasanian period.

Iranian Zoroastrians are known to have been trading with India for centuries before the dates calculated for arrival of Parsis per Qissa-i Sanjan. Ruksana Nanji and Homi Dhalla while discussing archaeological evidence for 'The Landing of Zoroastrians at Sanjan', conclude that the most likely date for the migration at the start of the middle phase of their chronology, namely the early-to-mid-eighth century. Nevertheless, they express their general skepticism about the Qissa-i Sanjan account. Scholar Andre Wink has theorized that Zoroastrian immigrants to India, both before and after the Muslim conquest of Iran, were primarily merchants, since evidence suggests it was only some time after their arrival that religious experts and priests were sent for to join them. He argues that the competition over trade routes with Muslims may also have contributed to their immigration.

Although historically unsubstantiated, the story of how Zoroastrians gained permission to step on the shores of Gujarat continues to be critical to the self-identity of the group. Per the commonly told narrative, the Rajah of Sanjan, summoned them and demanded to know how they would not be a burden on or a threat to the local communities. Replying to their request of practising their religion and till the land, he showed them a jug full of milk, saying Sanjan like it was full. In one version, a dastur added a coin to the milk, saying like the coin, no one would be able to see that they were there but they would enrich the milk nonetheless. In another version, he added sugar instead and claimed that like it, they would sweeten lands of Sanjan. In both of them their settlement is approved by the Rajah who addresses certain conditions for it: they would explain their religion, promise not to proselytise, adopt Gujarati speech and dress, surrender their weapons and only conduct their rituals after nightfall. During this period, Zoroastrian traders faced execution outside India, including in China where many were killed during the Guangzhou massacre.

The immigration of Zoroastrians to India continued, and by 1477 they had lost all contact with Persia. Not until three hundred years had passed would they come into contact. Zoroastrians also played a notable role during the freedom movements of India. There were also subsequent migrations, especially resulting from attempts of Safavids' to convert their subjects to Shia Islam in the sixteenth century. This added to the Parsi population and cemented their close association with Iran.
