Religion plays a large role in Iranian society. Islamic principles regarding law, politics and social customs continue to influence Iran’s laws and political interactions. The vast majority of the Iranian population (99.5%) identify as Muslim, mostly of the Shia denomination. Even though most of its people are Muslims, the country is home to numerous religions. Small communities of Christians, Jews, and Zoroastrians are also found throughout the country. You’ll see a predominance of mosques over churches and synagogues, as you travel around Iran. The influence of various religious beliefs, from its birth and through to subsequent periods of global recognition, highlight a rich and varied set of belief systems that have helped shape the nation today. Here’s what you need to know about the religions in Iran.


Ancients religions in Iran

During the ancient times, when the first tribes lived in the old land of Persia and organized the first cities and civilizations, they had their own legendary philosophies which little by little changed to Mithraism religion. Mithra was the god of faith and loyalty; but the first official Iranian religion, which was assigned during the Achaemenid era, was Zoroastrianism, and the lord was Ahura Mazda, the creator and the keeper of all the goodness in the universe. Zoroastrianism is the glorious religion of purity believing in Good words, Good thoughts and Good Deeds.

During ages and decades and in the result of cultural confrontations, wars and migrations other religions have entered Iran. A population of Jewish people has lived in Iran since ancient times, and Christianity in Iran was grown since the early years of the faith in two minority groups of Armenians and Assyrians. This is more than 14 centuries since Islam entered Iran and now it is the official religion in Iran.

Today, although the majority of Iranians are Muslims, minor populations with different religions are living in Iran and they have managed to keep their ceremonies and rituals alive and there are shrines cathedrals fire temples from different religions hidden in every corner of this aged country.

The prophet Zoroaster is regarded as the founder of Zoroastrianism, which is arguably the world’s oldest monotheistic faith. Most of what is known about Zoroaster comes from the Avesta—a collection of Zoroastrian religious scriptures.
