I'm interested in a list of religions that have either disappeared or significantly declined in followership in the place where they originated or once flourished. One example that I have is for Buddhism in India (former case), as well as to some degree Christianity in Western Europe (latter case). I'd like some more examples, if there are any (I'm sure there is at least 1 other example) of religions that have exhibited such phenomenon.

    Are you looking for something like Norse religions were replaced by Christianity as kings (and peoples) converted? – rougon Nov 1 '17 at 22:26

    The ancient Greek religion,Manichaeism, Zoroastrianism, gnosticism etc etc etc – Notaras Nov 1 '17 at 23:09

The best example I can provide you with is the Ancient Persian Zoroastrian religion.

Zoroastrianism, was either the earliest or certainly one of the earliest religions of Ancient Persia-(present-day Iran). The dates for the Founder of Zoroastrianism-(the Prophet Zoroaster or Zarathustra), are debatable, ranging anywhere between 600 BC/BCE-1000 BC/BCE. I personally tend to think that Zoroaster/Zarathustra lived around the 600's BC/BCE-(which was the same time when Persia, as a civilization, was uniting into a major power and preparing for their imperial campaigning across much of Asia).

The Zoroastrian religion was the national religion of Persia-(as well as neighboring Uzbekistan, though to a limited extent) for nearly 1300 years, until the arrival of the Arabs and the Islamic religion. When the Muslims conquered Persia-(specifically, the Early Medieval Sassanian Empire), the vast majority of its inhabitants were forcibly converted to Islam and a tiny percentage of Zoroastrians remained within Persia. Immediately before the Arab Muslim conquest of Sassanian Persia, a small percentage of Persian Zoroastrians migrated to India and have resided in India to the present-day-(they are referred to as, "Parsis").

Zoroastrianism is barely kept alive within contemporary Iran, though the Parsis of India have retained many of their ancient Zoroastrian practices into the present-day.

The eradication of Christianity in the Middle East comes to mind. In fact, it's history in the making, as it continues to this very day.

I noticed people find my answer incorrect. Probably because it's happening right now. That is not history, is it?
