Zoroastrianism Timeline

Zoroastrianism in the World (text)

Zoroastrian Legendary History

Pre-Iranian mythology relates the stories of kings and warriors of the legendary Pishdadian Dynasty, predating Zarathustra. According to this history, King Gayomard (Kayomarz) was the first mortal; from his seed grew Mashya and Mashyani, the first human couple. This history also includes the story of King Jamshid, who received a divine warning that the world would be submerged in ice and snow. He built a “Vara” (fortress) and to which he brought pairs of men, women, animals, and seeds. 

1,000 - 1750 BCE Zarathustra 

Sometime as early as 1750 BCE, the prophet Zarathustra began teaching about the worship of one God, Ahura Mazda. His teachings were remarkable for their monothesitic and dualistic qualities, which scholars believe influenced the development of Judeo-Christian western religious thought. Zarathustra proclaimed a life-affirming message that demanded not so much belief as reason, action, and an ethic of personal responsibility for every individual. He lived a life of reflection and active benevolence. 

728-559 BCE Median Empire

Around 728 BCE, Deioces founded the Median Dynasty in the city of Ecbatana. Later during the 7th century BCE, Scythian nomads entered western Iran from the Caucasus. Towards the end of this empire, Cyaxares overthrew the Scythians, and his granddaughter married Nebuchadnezzar II of Babylon. 

500-330 BCE Achaemenian Empire

In 500 BCE, Cyrus the Great conquered the Medes, the Lydians and the Babylonians, becoming the first Zarathushti world power and founding the Achaemenian Empire. At the time, this empire was one of the largest empires in history, stretching from modern-day Libya in the West to modern-day Pakistan in the East. During this empire, Darius I the Great (522-486 BCE) expanded the empire into Greece and Macedonia, and was defeated by the Greeks at the Battle of Marathon in 490. Additionally, Xerxes I (486-465 BCE), often known as King Ahasuerus in the Book of Esther, led a land and sea invasion of Greece. The Persians crossed the Hellespont to Athens and took the Acropolis.

331-248 BCE Seleucid Empire

In 331 BCE, Alexander the Great (or Alexander the Accursed) defeated the Achaemenian Empire and took control of Persia. His reign ushered in a period of Hellenization in which Greeks built temples designed to blend Zoroastrian and Greek religious practice.

247 BCE-224 CE Parthian Empire

A religiously heterogenous empire, the Parthians used religion as a diffuse source of influence through individual families to spread Parthian culture. 

224-652 CE Sassanian Empire

Throughout the Sassanian Empire, Zoroastrianism gained widespread power and was declared the empire’s official religion as Sassanians built fire temples (Zoroastrain places of worship) across the Middle East. During this time, a master copy of the Avesta, Zoroastrianism’s most important collection of religious texts, is created.

314 CE Armenia Becomes Christian

King Tirdat IV converts to Christianity and by tradition his subjects convert as well. Historical documents suggest that before this conversion, Armenia was likely majority Zoroastrian.

652 CE Fall of Sassanian Empire

After decades of attacks, the Sassanian Empire is absorbed by the Islamic caliphate. From this point forward, Islam becomes the primary religion of Persia, ending centuries of Zoroastrian power.

700s-900s Many Zoroastrians Convert to Islam

During the 8th-10th centuries CE in Persia, Zoroastrians must pay jizya, a tax for non-Muslims. Due to this economic discrimination, Muslim families take hold the majority of land in Persia as Zoroastrian families struggle. Most Zoroastrians convert to Islam, but Zoroastrianism survives despite the pressure.

861 CE Cypress of Kashmar Cut Down

The Abbasid caliph of the Khorāsān region orders that the Cypress of Kashmar, a sacred tree thought to have been planted by Zarathustra, be cut down.

900s CE Zoroastrian Texts Produced

Facing the destruction of fire temples and redaction of sacred texts, Zoroastrian communities launch a concentrated effort to record their ancient stories and practices.

936 CE Migration to India Begins

Facing persecution, Zoroastrians flee from Iran to India, which splits the global Zoroastrian communities into an Iranian group and a community known as Parsis in India. When the first group arrived, the raja (a local ruler) presented them with a full glass of milk, indicating that their land was filled to the brim and unable to accept more people. A dastur (Zoroastrian high priest) responded by pouring sugar into the milk and arguing that Zoroastrians would sweeten the land without overflowing the milk.

934-1055 CE Buyid Dynasty

The Buyids, Shi’i Iranian leaders, take control of Persia. They take an interest in Zoroastrian history and produce coins that feature fire temples. At this point, Zoroastrianism had been displaced and persecuted, but remains resilient. 

979 CE Riots in Fārs

Under pressure to convert from the caliph, Zoroastrians in the region of Fārs (modern-day Iran) revolt, showing that Zoroastrianism was still relatively strong in certain areas.

1000s-1500s CE Zoroastrian Dark Ages and Migration to India

During this period of upheaval and changing empires in Iranian history, there are few surviving sources which indicate how Zoroastrian communities fared. However, the great number of Zoroastrians that migrated to Indian during this time indicate that it must have been an organized community effort.

1501-1722 Safavid Empire in Iran

From the outset of the Safavid Empire, the Shah makes financial success difficult for those who do not follow Shi’i Islam. In 1699, a decree forces all Iranians to convert to Shi’i Islam. In the city of Kermān, jurists relocate Zoroastrians to the outskirts of the city to prevent them from mixing with Muslims.

1510–1591 CE Meherji Rana visits Akbar the Great

An important priest from Gujarat, Meherji Rana, pays a visit to Akbar the Great of the Mughal Empire, who loved to learn about different religions and even built a meeting house called  Ibādat Khāna (the House of Worship) to meet with spiritual leaders. After talking with Meherji Rana, Akbar then took up an interest in Zoroastrianism and kept a fire burning in his court.

The first fire temple in Bombay (modern-day Mumbai) is consecrated, indicating that Zoroastrian influence has spread beyond Gujarat.

1789-1925 Qajar Dynasty in Iran

Peterson’s initiation sparked arguments between Zoroastrians around the world as they grappled with the validity of conversion (Zoroastrianism is traditionally patrilineal) and the center of authority (some Zoroastrians in India felt that Zoroastrians in the United States were out of touch with tradition).

After a growth in Iranian immigrants to New York, tension rises between the Parsi members of ZAGNY and the Iranian newcomers, causing the Iranian Zoroastrians to branch off into their own group.
