Don’t get Zoroastrian confused with modern Iran. The Zoroastrians fled Persia due to persecution of Islam and moved to other areas, mostly British owned areas. Hence Freddie Mercury and his Zoroastrian family and his British education. His father was a British civil servant in Zanzibar even.
These people were far more advanced than many in that region and were smart enough to get the hell out when the corrupt Islam came along.
“The Zoroastrians fled Persia due to persecution of Islam and moved to other areas, mostly British owned areas.”
They moved into India (mostly) given India’s rich traditions of welcoming foreigners. The story of the Parsees who located wholescale into India following the muslim invasion is a moving one and I’ve visited the spot where the Parsees landed on Indian soil. Today, the Parsees (Zoroastrians) are located in their largest numbers in India (and that includes Fredie Mercury’s sister who still lives in Mumbai).
The British had nothing to do with the large scale Parsee migration after the destruction of the Persian civilization by the animal muslims.
There still are 25,000 in Iran.
